Friends, all welcome. If you decide to develop a manual arc welding by yourself, it will be another useful article on our channel, that you will help in this. And I tell you today thin metal electrode welding method, it turned out to hard and there was no deformation.
As always, I will still show on real examples from his welding job. Last week I cooked 2 metal doors for utility rooms (basement) .On the door leaf is used thin sheets of 1.5 mm.
On one door leaf Tselikov happened, but on the second I had to join metal sheets, since after cutting to the first door, from the remaining piece did not go whole cloth.
Thin sheet metal electrode when welding is carried out very strongly and deformed, and in this case I of this was to be avoided, but firmly weld the sheets. Look what I made.
I will be their welded overlap, as if to do it back to back, then there is such a strain that already does not fix it. I have marked an overlap space, and more important point-a piece of a smaller sheet that will be welded to the main I sawed off with reserves width and height, so that when fielding and welding it even slightly will not quit, and the right size, we will modify the grinder after welding.
And here is the welding method, whereby a thin metal sheet is welded firmly, and moreover, will not be deformed is elektrozaklopkami welding. The bottom line here is simple-I welding arc burns through the top sheet overlaps and is welded to the bottom. So I cooked these metal plates here such weld points.
The key here is to press the sheets together tightly as possible, a very strong connection is obtained.
Take grinder we clean and weld nuggets elektrozaklopok, visually inspect the coupling place sheets, everything is fine, the metal sheets are welded together firmly, and there is no indication anywhere strain. Now clipped welded sheet size necessary to us.
Now we catch this now one piece to the door leaf box with overlaps of 10 mm around the perimeter, then marker note on the corners of the sheet position in the box, so that later, after the welding of the sheet and the frame door, grab it all at the same a place.
So we boiled door frame and sheet metal, and snatched back to the box, focusing on the marks left ahead marker. Now, in this position, we will weld the loop, how to weld hinges properly, strictly in line to work flawlessly, I'll discuss in the next article.
This method of welding thin metal, of course, is not a guide to weld exactly variants Welding much, just such a method is quite simple and accessible, even for beginners, and the result is quite not bad.
