All welcome. We continue our welding diary. Today I want to uncover an important subject as the beginner learn how to make durable and beautiful seam. We will be under it to bear in mind that we learn to cook the inverter and the electrode. Better trained on the metal thickness of 2-3mm, with thicker metal, of course it will be easier, but we need to make it difficult to learn, so that later it became easy in battle! So we take a piece of metal, we expose the welding current to the ignition electrode if not immediately burned through the metal and to burn of burning a few seconds - so the current will be the best for our purposes, and will not stick electrode, and the refining of normal out.
Boil will dots lit to make a point, the electrode was removed, etc. The main thing enemy novice - is a rush, want to quickly make all and I think that will be durable and beautiful. But no, it is not necessary to rush here, even do not need to rush Here we put the point - it is red-hot, the contours are clearly visible and are like a coin. Cant beginners is that they put the coins one after the other - much less than you need.
And so the seam is obtained krupnocheshuychaty and ugly. With such bad bounces weld slag, and it is not particularly robust.
And to do so - put the first point, but interrupted while the contours of the first point can be seen, the second point is half reimplemented the first point, third Cover the halfway point of the second point, and so on to each other, similar to fish scales - each lamella overlaps about half previous.
And in this case we get a beautiful and quality seam from which the slag is very easy to withdraw. As one of my friends a good welder, beautiful seam - strong seam.
Thus, the seam for shovchik fills his hand, slowly, learn. Over time, we begin to try to cook not points, and short shovchik, but never forget that rules - reimplemented after the separation electrode to cool the welding point of the next half point. So you learn to cook beautiful and durable, but do not expect immediate results, but it's worth it.
