All welcome. Let's will fill up once a useful article, our welding diary. Today will analyze such an important for a beginner in welding theme as the slope of the electrode and the welding direction with the slope. Let us bear in mind that we cook a piece of iron in the lower position. Here we took a mask and derzhak and struck a metal electrode of the arc on fire and what to do next, in what direction you need to keep the electrode? There are only three options inclination electrode for welding.
Well welding at right angles to a phenomenon quite rare, so we assume that the cook will angle forward or backward angle. What would really simplify the understanding of this process, just imagine watering the earth from a watering can - if you water and go forward, it will be a welding angle analogy forward, watering and pyatites ago - respectively, similar to the welding angle ago.
Well, we all realized, and how well we cook? When welding angle forward arc is melted base metal is not particularly deep and wide seam is obtained, with this method of welding slag is much easier to flow into the arc, preventing the normal welding. Apply desirable for welding thin metal - 3 mm, especially which is obtained by butt welding edges. But gusset even of thin metal in such a way to make more complex - the slag is strongly flows into the welding bath, and interferes with the normal process may be lack of fusion. So ideal for butt welding of thin metal. Accordingly, the moving angle back, get deep penetration and good metal control weld pool. So cook all more or less thick metals - can be from 3mm or more. To summarize angle forward - we cook thin metal corner back - the thicker metal.
