Friends all welcome. Welding process itself is not easy, especially for a beginner, but there are situations when it is necessary to weld in confined spaces, which direct the electrode to get virtually impossible. That's about a case, and how we will be to understand today in this situation.
For a visual example, I gathered here is a layout of two scraps of profile pipes and brackets, which will place us close welding, to the same profile pipes are not in the same plane, and the right taken with the removal of about 10 mm relative to the left, because in welding, will meet the situation is much more difficult.
Vertical seam to the place, covered area of difficulty does not represent us. But to the place where the corner closes the pair of shaped pipes, get and normally boil direct electrode, will be a big challenge. And what do we do in this seemingly hopeless situation? The solution is always there!
We take an electrode and just simply gently bend it in an arc in this way it will be possible to make this remote place. It turns out here such manual arc welding!
Here is another point with the arc electrode, the last 4-5 cm into the arc to bend hard, and so this straight stretch, we slept on an unnecessary piece of iron.
That's it, in a way we've got to brew this remote place, below the chalk I marked the border, after which was prihvachen restrictive area. Of course under the seam area it was more extensive, but it's not scary, because we have achieved their goal.
But talk about another aspect of such welding. Bend in an arc possible only with rutile electrodes. If we take the basic electrode, there is nothing we will not be able to-crumble coating. For example, take two basic electrode-MTG left and right LBshka, and look what happened-it is a pity of course, these electrodes are spoiled, but it will be obvious example.
And until the pile spoiled one basic electrode-UONI 13-55. As we can see, too, could not resist coating. But for these electrodes and do not need such complexity, they welded more responsible design and for our domestic needs and garage will be bent into an arc rutile electrodes. Incidentally, in this example I took MONOLITH electrodes 21 as well ano bent into an arc. But Mr3 can say for sure, have not used them, who knows unsubscribe in the comments, what else can be applied without damaging the plaster.
I hope many beginners, this article will be useful and will help to solve many of the problems with welding in confined spaces. I suggested this method many years ago an experienced welder, for which I am very grateful to him.
