Entrance metal doors of Chinese manufacture are not of high quality, but they are still in great demand among apartment owners, because they are cheap.
One of the most common reasons for repairing a Chinese door is because the hinge is broken. There are such "branded" doors, where the hinges simply come off.
However, this problem can be fixed. The metal, of course, is thin - about 0.45-0.50 mm, but the hinge can be welded into place, and save on buying a new door.
To do this, you can use a conventional inverter apparatus and piece electrodes, rather than a semiautomatic device with a wire, which not everyone has available.
The main stages of work
First of all, in the place of the "accident" it is necessary to peel off the rubber band. Then the metal must be cleaned with a grinder with a petal circle.
At the next stage, the "flown" loop must be grabbed. For this, the master uses an electrode with a diameter of 2 mm. The current strength is about 30-40 Amps. In general, it is advisable to select the optimal current strength experimentally on a plate of the same thickness as the metal of the door itself.
After this tack must be cleaned with a grinder. Next, you will need to install the door on the hinges, and check whether the hinge is level. If everything is in order and there is no skew, you can weld the loop completely.
