Learning to weld the hinges on the gate - step by step instructions

gate functionality is based not only in their secure locking, holding power loads and strength, but also an easy opening / closing.Ideally, the latter two characteristics, as well as the absence of gaps between the closed gates are achieved through high quality welded loops.Anyone who knows how to use the manual electric arc welding, weld quality will hinge to the gate, if they know how to do it correctly.

As welded hinges on the gate

opening and closing the gate without scratches and jerks - is the best that can give the correct installation of loops.How to achieve this?First, choose the correct method of installing loops of a material gate and supporting pillars.Gates made of metal, wood, or of corrugated polycarbonate, metal poles, wooden, concrete, foam concrete, brick, stone or cinder block: select the loop will be best ball anyway.The cavities of these loops are the balls, which are much easier to move the gate.

First we need to inquire how the hinges on the door in a pair: one wing of the portal both loops must be in a mental held straight center line.That is, after the quality work of the lower loop must be just below the top, and both loops should be smooth axial location in space.With this welding of the door hinges weight load is distributed evenly on a hinged support.

Start of

cylindrical form loops often leads inexperienced welders to ask: "And this is all being cooked?".Brewed.Hinges made of hexagon or tetra actually harder to cook.On the right loop technology to start welded to special platikam.Do this preferably on a flat surface, such as anvil (at the same time it is possible to attach a "minus" welding machine).The inherent requirement platiki welded to the loops must be a continuous weld.

Choose the appropriate size platik not difficult.We take into account the weight of the gate and the strength of the material from which they are made and determine at a glance how long the weld could withstand the weight of the door and not let the structure be deformed.Platikami organized comfortable working "playground" for welding work, as well as they serve as the distributor plate of portal web that does not allow the latter to "break" even if the overall heavyweight portal design.

Gates mounting

weld loops to the already welded platikami need fixed, pre-placed gates in the "home screen".That is, the gate will have to fix the "idle" and reach their desired position before the start of welding.Position door should double-check as many times as the average first grader knows the numbers - at least ten.

Welding

After you have made a thorough check of the gate location, pre-measured and tagged fields for plates, you can start welding with the lower hinge on the pillars.Vertical joints - this is the most difficult job for the welder.Even an inexperienced welder will be able to cope with them through the plates.When one part of the bayonet hinge on the leaf will be welded, it will be possible to use a laser level to verify the correct positioning of its axis and to determine the exact location of the second bayonet hinges.

Completion

After careful welding bayonet parts of loops on the pole, they will need to fit flush plug upper part of the loops at once with balls.After that, how can more tightly pressed to the baiting of the door leaf and continue welding.

At the end of welding seams can be treated grinder.

This technology has long been successfully used by all services Installation of doors.Do it yourself is easy, if you have the skills for the welding and the necessary equipment with consumable:

• metal hinges;
• Plates / platiki;
• welding machine;
• electrodes;
• Bench hammer;
• welding mask, gloves and protective clothing;
• Bulgarka.

Note that the gates should be opened to the outside, because if the door opens inwards with abundant snow in the winter - it can become a big problem!
