How to properly weld canopies on gates. Learning how to weld hinges on gates - step-by-step instructions. Selection and preparation of loops

The gate should open and close smoothly and fit snugly against the walls. This is why experts recommend welding metal loops to them. However, before this, you need to figure out how to properly weld garage hinges so that they hold securely.

Before installing opening elements for gates, you need to understand the main types of hinges. Varieties of loop products differ in the material from which they are made and in shape. Also to distinctive features can be attributed to the service life and appearance.

There are four types of hinges that are most often used when installing garage doors:

• Cylindrical. This type is attached to gate leaves and posts. It is cylindrical hinges that are most often attached to gates, as they ensure their smooth opening. The design consists of a pin and a metal cylinder that is put on it.
• Reinforced models. The products have durable metal bearings, as well as additional iron plates that make the hinges much stronger.
• Through. They are installed in racks and attached to them with bolts and nuts. Experts advise using through structures to hide the hinges in the supports. The main disadvantage of through-type products is the complexity of installation.
• Three-section. They are considered the most expensive and reliable hinges, which are installed to additionally protect the gate from burglary.

Drawings and diagrams

Some people prefer to make their own gate hinges. However, before this, you need to make a product diagram, the development of which takes into account the following parameters:

• Strength and section diameter. When determining these parameters, the weight of the gate that will be installed in the garage is taken into account. For example, if they are made of a metal sheet five millimeters thick, you will have to install loops with a cross-sectional diameter of 2-4 centimeters.
• Length. If the garage is closed with a heavy gate weighing more than two hundred kilograms, hinges 20-25 centimeters long are welded. Thanks to this, the dimensions of the weld seam will not exceed nine centimeters.
• Gap. Garage owners often experience their gates jamming when opening. To get rid of this problem, a gap of half a millimeter is made between the hole and the axis.

Loop welding technology

To install the hinges correctly with your own hands, you need to familiarize yourself with the technology of welding them.

Installing plates

Experienced experts advise using small metal sheets called plates. They must be welded when installing round hinges. To install them, you do not need special, hard-to-reach tools.

It is enough to use a welding machine that reliably connects metal elements.

The plates must be welded with an even seam so that they are securely attached to the surface of the loops. Hinges can be installed on the gate only after the plates have been welded.

We install gates

Before installing the garage hinges, they install the gate leaves in the opening. This procedure is quite complicated, since it is not easy to install the sashes yourself. Experienced builders advise using a building level to ensure everything is installed level. It is contraindicated to perform such work by eye, since it will not be possible to install the sashes evenly without a level.

Attaching hinges to supports

Many people who do not know anything about welding equipment and welding believe that welding eyelets to supports is very difficult. However, if you become familiar with the installation features of such products, the work will seem less complicated.

The fastening process is carried out in several successive stages:

• Lubrication of hinges. First, the products are treated with machine oil, and they are lubricated in such a way that it does not flow down the hinges.
• Marking. Marks for welding are made on the fabric to which the loops will be welded.
• Welding to the canvas. To ensure that the structure is securely fastened, the bayonet parts are first welded, after which everything else is secured.
• Welding check. To check the evenness of the installation of the hinges, use a building level.

How to treat the surface of hinges

Immediately after installation is completed, the products are processed with a special grinding machine, which will eliminate uneven weld seams. Once the surface is sanded, you should think about protecting the surface of the hinges from corrosion. To do this, they can be coated with the following types of paints:

• Alkyd. To coat metal products, alkyd paints are often used, which are available in the form of enamel or oil-based compositions. Experts do not recommend using enamel, as it does not tolerate high temperatures and is subject to combustion. Oil mixtures are much better and safer. They are made from natural oil and drying oil, which does not deteriorate under the influence of sunlight and temperature changes.
• Acrylic. They began to be used for processing metal surfaces relatively recently. Just a few decades ago, no one used acrylic paints to coat iron structures. Today, manufacturers produce paints that protect coatings from corrosion and extend their service life. Even 2-3 years after painting, the surface does not crack or fade.

Shelf life of the product

Many people are interested in how long gate hinges will last. The shelf life of such products directly depends on the quality of their manufacture and installation. If securely welded hinges are properly cared for, they will last for decades. Poorly welded products may break the next day.

These are support loops through which the canvas is hung on the frame base. At the same time, only competently carried out welding operations allow for high-quality hanging of the door leaf and ensure the safety of their operation. In this article we will look at how to weld hinges on garage doors.

Types of gate hinges

Gate hinges can come in a wide variety of shapes. In the practice of garage construction, hinges of various shapes are most often used:

• cylindrical;
• square;
• hexagonal.

Cylindrical hinges, despite their unusual appearance, are welded to the base much easier than any other. That is why we will choose them as the subject of consideration in our article. To make it easier to work with such hinges, metal “ears” are first welded to them, the size and shape of which are selected based on the dimensions and total weight of the gate, as well as taking into account their decorative qualities.

Note! To increase the service life (due to improved sliding), it is advisable to choose hinges supported by a ball inserted inside, used as a bearing.

First, it is necessary to carefully check all the installation dimensions of the structure, ensuring the placement of the canvas in the frame harness With a gap of no more than two mm. Only after this can you begin to mark the places where the hinges will be welded on the canvas itself and the frame. In this case, it is necessary to ensure accurate alignment of the hinge seats, which, after welding, must be located strictly on the same center line.

To prevent unauthorized removal of the gate, the hinges must be welded towards each other or equipped with a special stop to prevent this.

Installation procedure

Before starting installation work, you will need the following working tools:

• electro welding machine with a set of electrodes;
• a special grinding machine with a disc for metal processing;
• level with a plumb line, tape measure and hammer.

And only after all installation dimensions have been verified and the necessary tools have been prepared, you can proceed to the main operations.

Note! The location of the hinges in the vertical plane must be controlled by a plumb line, after which it will be possible to tack it by welding at several points. The same should be done with the mating parts of the hinges mounted on the gate frame.

In this case, you should start with the lower hinges, after welding them you need to check them again for alignment (preferably using a laser level). Immediately after this, the upper hinges are grabbed, after which the gate can be checked. During this hanging process, the gate is checked for ease of movement, as well as for the presence of the required clearances.

If the result is satisfactory, the hinges are finally welded in the same sequence (first the lower fastening, and then the upper). When installing hinges, due attention should be paid to the verticality of their installation line, as well as the aesthetics of welded joints. To make the seams beautiful, they can be processed using an angle grinder.

Some subtleties of installation procedures

When carrying out installation work, the following features of welding procedures should not be overlooked:

1. When welding gate hinges, it is advisable that welding current did not leak along the supporting hinges. This is necessary so that welding tacks do not form in the loop itself. For this purpose, when welding the hinge, the contact clamp with the “ground” must be fixed on the sash itself. In the case of welding a loop to a strapping element (to a stand, for example), the clamp with “ground” can be transferred to this stand.
2. To eliminate possible welding deformations, the hinges must be welded to the canvas and the box “crosswise”.
3. When hanging gates on vertical metal posts, be careful to leave a gap that allows the gate to open completely. (In the case of supports with a square cross-section, this need does not arise).
4. If the gate has a significant mass, you can organize lubrication of the hinges by installing a special grease nipple in them, which ensures oil supply to the area of ​​maximum support load.

Work safety

The organization of welding work of any class requires the contractor to comply with safety requirements. In this case, first of all, you will need to worry about the availability of appropriate protective equipment (special shield and gloves).

In addition, to ensure the required safety, welding work must be carried out in a well-ventilated area or in the open air, at a sufficient distance from flammable and combustible materials.

When repairs are made and the area is being improved, one of the most common operations is welding hinges. It should be noted that welding hinges to the gate correctly is not so easy even for specialists, and if we are talking about beginners, then they experience a lot of difficulties. So how to weld hinges for those who do not have relevant experience in this matter, and is it possible? It is quite possible for people with no experience to weld hinges to the gate themselves.

But it must be taken into account that such an operation involves some nuances. First of all, you will need the following tools:

1. Hammer.
2. Roulette.
3. Building level.
4. Welding machine.
5. Protective mask.
6. Protective gloves.

How to weld hinges? General rules

When welding is carried out, safety precautions must be followed to help prevent injury. Among the safety measures, special attention should be paid to the fact that you must work only in a protective mask and special gloves. Under no circumstances should such work be carried out in places where there is dry grass, otherwise a fire cannot be avoided.

Welding the gates must be done carefully and very carefully, this will result in a gate of excellent quality.

It is necessary to retreat approximately 20-25 cm from the bottom and top of the canvas (it is to the canvas that the hinges will need to be welded), this distance should be measured with a construction pencil. Then the hinges must be thoroughly lubricated with grease; this must be done so that the hinge halves do not sinter during the welding process. To do this, place a match under each of the loops along the edges. With the help of such a simple manipulation, you can ensure that the door does not jam during welding work.

The door leaves must be wedged so that when closed the doors are in the correct position; for this, the door leaves are pre-aligned.

When the hinges are welded to the gate, they should only be lightly welded.

In this case, you must remember that the lower half of the part is welded first. Those who use a welding machine for the first time need to know that the loop should be welded from the bottom up, and the movements of the electrode should be horizontal and not sharp.

After the first seam is welded, the gate must be wedged and checked to see how well it opens and closes. The hinges must be permanently welded, but only if the doors function well. This should not raise any doubts; this is the only way to weld the hinges to the gate correctly.

After all this, the frame is removed from its hinges, thoroughly coated with grease, then it is carefully seated in place. The places where welding was carried out must be processed with a grinding machine, after which the entire product is coated with paint. The ideal design is one that opens quickly and easily, and should close with one easy movement of the hand.

It is not recommended to carry out welding work alone; this causes certain difficulties. But if this cannot be avoided and there are no assistants, then you can weld the hinges to the gate on the ground, but you must immediately take into account that the quality of such work cannot be called impeccable.

What not to do when welding hinges?

What is forbidden to do when welding, how to properly weld hinges to the gate so that there are no negative consequences? Here you need to consider the following:

1. Under no circumstances should you operate equipment that is faulty.
2. There is no need to carry out welding work until the paint has completely dried.
3. You should never carry out welding work in clothing that contains traces of oil, grease, gasoline, or other flammable liquids.
4. Welding of pressure vessels is strictly prohibited.
5. Do not hang rags or rags soaked in oil on the cylinders. This is what often caused fires.

If everything is done correctly, the result will be impressive, and you can then advise your friends on how to weld hinges reliably and efficiently.

Gate hinges are a simple device that serves to attach gates to posts, as well as for easy opening and closing. The reliability of the design and ease of operation depend on the choice of this mechanism.

They are mainly equipped with hinges, which can be quite heavy. Therefore, special attention must be paid to the quality of installation, namely the fastening of hinges. A person who knows how to handle electric welding can weld hinges on the gate themselves, but those who do not have such skills are recommended to turn to professionals.

Welding rules

In order to prevent the gate from sagging and to avoid problems with its operation in the future, all work must be carried out taking into account certain features. Therefore, first of all, special attention should be paid to:

• The integrity of the weld, which must be continuous, that is, without gaps.
• Welding depth - the loop must be welded along the entire plane adjacent to the support.
• Axial location - all hinges on the sash must be in one straight line so that the load on the seams is distributed evenly.
• When determining the number of hinges, if the gate is massive, it is recommended to supplement the design with another pair.
• Dimensions - all measurements are made using tools designed for this purpose, and not “by eye”.

Welding technology

It will be much easier to weld the hinges correctly if you follow the rules of the sequence of the technological process. The sequence of work is as follows:

1. installation of plates;
2. gate installation;
3. welding of hinges.

Now we will analyze each of the stages separately, using the example of circular loops (turned).

Video: How to properly weld hinges with your own hands.

Installation of plates

Platik is a metal mounting plate that serves both to distribute the load evenly and to simplify welding work. The size of the plate and its shape depend on the weight and dimensions of the valves.

It turns out that in order to correctly install the loop, you need to weld such a plate to it. This is done with a continuous seam, without gaps. Experienced welders can weld without plates, which is quite acceptable, but the fastening will not be as reliable.

Gate installation

Before welding the prepared hinges, it is necessary to install the gate in the opening. This must be done the way they should be on a permanent basis. For installation, use a long building level or plumb line.

The gates are aligned in all planes: vertically, horizontally. Only after making sure of their correct location several times can you move on to the next stage.

Welding hinges

This process seems complicated only at first glance, but with a little practice you can do everything yourself.

This is done as follows:

• The hinge is lubricated with automotive lubricant (solidol, lithol, etc.), this contributes to their smooth and easy operation after installation.
• Thin linings up to 5 mm thick are prepared; this is mainly required for turned hinges.
• Markings are made - the loops should be located at a distance of 30 cm from the top and bottom.
• The hinges are welded in several places, first to the sashes and then to the pillars. After checking for closing - opening, welding continues until a solid, even seam is formed.
• After the seams have cooled, they must be sanded and primed or painted.

This technology is used by almost all door installers.

Incorrect welding can lead to problems during further operation; to prevent this from happening, you should listen to the following recommendations:

• Before starting work, make and study a schematic drawing; if all the details are taken into account in advance, then the risk of redoing the finished structure will be much less;
• straight hinges are welded to the gate laid on a flat surface;
• You can open gates with newly welded hinges after the seams have completely cooled;
• on round posts the loop extends 5 mm outward, on rectangular posts it is welded flush;
• the welding seam should go from bottom to top.

Types of loops

Loops for can vary in shape, number of sections and method of fastening. The most reliable, and therefore the most popular, method of fixation is welding.

All other loop parameters depend on the type:

1. Cylindrical hinges – equipped with a support bearing, designed for gates of light weight. Permissible load– 400 kg. Attached by welding.
2. Cylindrical with reinforcement - they differ from the previous ones by the presence of a special plate to distribute the load between the sash and the post. Maximum load – 600 kg. Fastening by welding and screws.
3. Through hinges are used where it is not possible to use welding or a screw connection. They are fastened in the following way: the post is drilled through, and the connection to the sash is made with nuts. Maximum load – 200 kg.
4. Three-section overlays - designed for massive sashes, with them there is no risk of sashes sagging or squeaking, and opening will be smooth. In addition, such structures are famous for their increased burglary resistance.
5. Zhikovinas (forged hinges) - in addition to their direct purpose, also serve as decoration, giving the gate a special colorful look. Mainly used for wooden structures.
6. Hinge - boom, hinged or half-hinged - used for heavy and thick gates, doors or wickets. Available: regular, curly and removable. The best option for massive

Fence gates are a very important component of any modern fencing. They will perform not only the function of entering a car, but also protecting the territory from unauthorized entry, decorative functions, and so on. Since today gates can be very heavy, they must be installed very carefully, special attention should be paid to welding the hinges. This is exactly what we will talk about today.

General rules for welding hinges

In order for the installed hinges to work properly and last a long time, and for the gates not to sag under their own weight after time, all work should be done according to the rules and very carefully.

So, what should you focus on when welding:

• The evenness of the seam and its continuity. The weld should be as complete as possible, without gaps.
• Maximum welding depth. Ideally, it is necessary to weld the hinges with the entire plane that is adjacent to the surface of the post.
• The canopies should be welded very evenly so that there is no excessive pressure on them during operation and in a standing position.
• For heavy structures, it is necessary to supplement the hinge system with an additional pair, which is located slightly below the upper load-bearing hinge.

In general, there are no more rules, but these should be adhered to and taken with complete seriousness.

We weld the hinges with our own hands

As you know, there are different types of gates and hinges should also be welded to them in different ways. Next, you will learn how to secure hinges on a round and square post. We will also tell you how hidden internal hinges are installed on gates or wickets and how to weld hinges on gates made of profile sheets.

Installing awnings on a round pole

In order for the awning to function normally on a round post, it needs to be slightly moved away from it. To do this, it is best to place a small metal plate under it, about two to three millimeters thick.

When welding canopies to a round post, push them outward by 5 mm on it and on the gate. This will eliminate the gap between them when closing.

Also, from the middle of the post, the loop should extend to the outside by five to six millimeters. Then the gate will be installed exactly in the middle, and the loop will be able to move along its axis without jamming and very smoothly.

We weld the curtains on a square support

Here it is already necessary to install the hinge flush. It is not necessary to make a lining, but it is better to play it safe and do it. First, apply a loop and grab it with several points so that it holds on its own.

You need to cook from bottom to top using small oven mitts and follow the order of work.

After that, take an even wooden block or a metal corner and align the loop with it so that it stands level, simultaneously checking everything with a plumb line.

To eliminate possible welding deformations, the canopies must be welded to the canvas and the frame “crosswise”.

After both hinges are secured, you should put the gate on and check its movement, if everything is in order, continue welding. At the end, clean the seams with a grinder and you can paint them.

Installing hidden internal hinges

If you want to keep the hinges out of sight, making your gate more attractive, then you should use special hidden hinges for internal installation. But it is quite difficult to install such hinges and you need to have skill and dexterity in welding; if you are an unprofessional welder with experience, then you will not be able to master such work.

It is best to entrust the process to a professional, then the installation will be done efficiently and the gate will be installed reliably and for a long time. Of course, you will need to pay money for such work, but the quality is worth it.

Installed on a fence made of profile sheet

The process of installing hinges on such a fence is somewhat different from the standard one, although there is also nothing super complicated or time-consuming in it, you just need to have the desire and strive to get the highest quality result from the work done.

Metal hinges for gates made of corrugated sheets

So, the entire installation process consists of the following stages:

• Two small jumpers are made, align them parallel to the long side and secure them at the top and bottom, respectively.
• The distance between these jumpers will make it possible to install three such elements.
• We weld our hinges to the installed jumpers.
• The profile sheet must be screwed on top of the installed hinges, since during welding work it can simply burn and lose its attractive appearance. Garage door hinges are best suited for such purposes.

Why are mounting plates used?

Such plates help simplify work and lighten the load on the curtains. They are welded in advance before the installation of the hinges themselves begins.

The dimensions, shape and thickness of such plates will depend on the parameters of the gate that will be installed. In addition to lightening the load and installation, such elements can perform decorative functions.

What not to do during welding

In order for welding work to proceed without incident, it is necessary to adhere to certain rules:

• Be sure to use protective equipment to avoid harm to your health. This kit includes a protective mask, gloves for welding, a thick jacket or shirt, and pants.
• Never touch a hot welding seam with oil-soaked rags, as they may catch fire.
• It is strictly forbidden to carry out work by eye, even if you are confident in your eye and skill, double-check everything with special tools, then the result is guaranteed to be of high quality and durable.

Now you know how to weld hinges yourself and you can share this information with your neighbors or friends who are still wondering how to weld hinges on their gates without any problems.
