Guys, all welcome. Today will tell beginners a simple and sure way to brew inconspicuous crack on thin metal. With a thick metal in this situation is not a problem-knifed and deepening rift sanding disc grinders, and cook just for this furrow!
But with a thin metal will be more difficult, the Bulgarian is not zarezhesh-otherwise there will be nothing to cook, so when welding thin metal, the crack is not always clearly visible, both to be here? I'll tell all on an actual example.
For example, more or less adequate, I had to dig with his father in the barn, where they found an old bayonet spade with a pretty good crack. And on it we will produce welding manipulation, and at the same time to repair it, soon spring will come in handy on the site.
The place where the crack is smoothed by a metal brush rust-normal metal is very important.
After that, with the help of fine crocodile-such homemade adapt, about it there is a separate article on the channel, we have pulled together as much as possible and put the crack tack. These are small cracks, although this is not as fine and is just an example, can put a beginner in welding in a difficult position, especially since they are not always straight, but are curved like here.
And help us in this situation, a simple piece of chalk. Just take the chalk and the conduct of the crack, completely repeating its shape. Just chalk is clearly visible through the mask during welding, and even next to the welding arc it does not burn and is an excellent reference. Welding produce points, putting you next point when the previous begins to fade, to avoid burned thin metal. It is important to be well cleaned of dirt and rust this crack before applying chalk, or rust with chalk will burn quite far away from the arc. And of course better to use a mask c nezabryzganym glass.
That we're all stirred up our crack, and at the same time another one in the same way. So you can safely use the chalk, when there will be a situation where the place of the weld overlay is not always clearly visible welding.
