How to weld hinges on a gate - step by step instructions How to properly weld the hinges to the gate + video

Such a simple matter, how to weld the hinges on gates almost always turn into difficulties and challenges. For most people, it is much easier to weld a frame of the correct geometric shape of a wicket and a gate than to install ready-made structures in place and ensure that it functions normally.

In fact, the work is not so difficult, but it will require the utmost accuracy and precision, as well as knowledge of certain nuances.

Selection of hinges and their number

If you have decided to use welded-on hinges for mounting the gate, then you can choose from certain types:

  • The most inexpensive and simplest option is a split-type cylinder with a rotating shaft in one place and a capped cavity in another. Such hinges are in great need of periodic lubrication, without which they begin to creak quickly.

  • The most popular hinges are of the same design, but improved by a bearing or ball on which the axle rests. They are both two-section and three-section.
  • Another option is to sing with metal plates welded to each element.

Please note that welded hinges most often have a round cross section and when assembled will resemble a cylinder. But their cross section is drop-shaped, with a sharpness along the walls.

The configuration will in no way affect the performance of the product, and it is also selected exclusively for ease of installation - it is more convenient for someone to attach one, and for someone else. But in fact, it is not enough to know exactly how to weld the hinges to the gate - first you need to calculate the load on them and determine the number. This is not so difficult to do if you know about the weight of the flaps.

Hinges that do not have plates can handle a maximum of 4 centners depending on their length and diameter, as well as the thickness of the metal. And the loops with plates that take on all the loads that are designed for a larger weight - they are able to withstand up to 6 centners.

Knowing the calculated type of load on the hinges, as well as the structural weight, you can determine their required number. Naturally, less than two pieces will not work per sash. And if the gate is heavy, then the number of awnings should be 3-4. An additional loop is required to be installed slightly lower than the upper one, which will bear the main load. By the way, you can even strengthen simple loops on your own by welding to them plates of the required size cut from metal with a large thickness.

The weld should be solid.

Technology for welding hinges

Before talking about how to weld hinges for gates, you should consider in detail all the conditions that are necessary for their normal performance.In the event that the load is calculated correctly, the hinges may not cope with it if their position deviates even slightly from the vertical. They will fail quickly. And now about the second point - a small gap of 0.

1-0 should remain between the hinged body and the support post. 2 cm so that the metal post parts and the counterpart of the canopy do not touch or rub against each other. The same gap must be left on the sash side. To understand all the nuances, you need to watch the video.

Features of mounting on poles with different sections

Support-type pillars on which the sash will be hung can be square, round or even rectangular in cross-section.

There is a difference between how the hinges on the gate should be welded to round-type posts or to profile support pipes.

  1. How to weld hinges on a gate - step by step instructions If the profile pipe has smooth edges without bends and curvatures, then cope with the task as it will be quite simple to weld the hinges on the gate to square-type posts. They are installed on the outer reference plane.
  2. In case we are talking about a support with a circular cross-section, it is necessary to first decide in which direction the sash will open. Next, find the most protruding line (the middle of the post relative to the opening) and step back about it a couple of mm outward - towards the opening.

    0.5 cm is enough for the gate leaf or wicket to "walk" smoothly, without jerking around the hinged axis. Since it is much more difficult to attach hinges to the gate to round-type posts than to square ones, and here you need to be especially careful and careful, maintaining the same indentation size for any hinges.

Now let's talk about installation.

Installation and welding work

Experienced craftsmen recommend to start weld canopies to the shutters, lay them on a flat horizontal surface.

Weld half to them in the form of a hollow cylinder, and to the supports in the future - a counterpart with a pin (and the pin should be directed upward).

Approximately 0. 15 meters should be retreated from the bottom and top edges. Next, install the sash with welded canopies in the opening on supports that will provide the required distance from the ground, and firmly fix it with pliers, clamps and other mechanisms. This is done so that it stands exactly vertically, and a gap of 0.

5 cm remains between it and the support. For this, a laser level or plumb line is used, and spacers of the required thickness must be inserted between the elements. The rest of the craftsmen prefer to first put up the wicket, and then weld the hinges to it, and also to the post. There are no big differences, and everyone does it the way it suits them.

Good advice! Install the gate in such a way that the leaves are perfectly aligned in level, rather difficult.

So that they do not move in the working process, they can be temporarily tied together by grabbing them through the jumper by welding.

Now let's talk about how to weld gate awnings. The working sequence is as follows:

  • How to weld hinges on a gate - step by step instructions A wire with a thickness of 1 is wrapped around the loops from below and above, and then twisted . 5-2. 5 mm so that a gap appears between the welding plane and it.

    You can also put matches or other objects of suitable thickness, but they will fall out, break or move, which is extremely inconvenient.

  • On the supports, it is required to place places for attaching canopies and apply a long even bar or profile pipe to them. Fasten it to a level, ensuring an upright position.

How it looks in reality

..

., look at the video:

Loops with wound wire are pressed to a bar and a pillar and also fix upright.

Please note that the earth cable of the welding machine is hooked to the place of the canopy that will be welded. If you install it on a support, then ultimately from contact welding, the looped halves can interlock with each other.

  1. The hinges must be tacked by welding to the supports in a couple of three points.

  2. In the same way, grab the second (namely, the upper) part of the hinges to the frame or sash leaf.
  3. When the tacks are frozen, the gate should be checked for opening - it should swing open 180 degrees without jamming or twisting.
  4. If everything is fine, the sashes should be closed again, fixed and welded to the finishing hinge with a continuous seam, from bottom to top.
  5. Clean the cooled seams with a hammer from scale and grind with a grinder to give a more beautiful look. But this work must be done carefully so as not to damage the joints.

You do not need to open the gate until the weld seams have completely cooled down and gain strength.

Conclusion

So, you have already learned how to weld the hinges on the gate, and you can do it with screws or nuts. The welded method is more durable and reliable, especially if you know how to weld the hinges to the gate and correctly make all the requirements that relate to the installation technology.
