Moving on, the stick or welding rod used in this process is usually covered in a flux material. These rods are available in different lengths and diameters. To produce high-strength welds, it’s very important to pick the right filler rod for your intended purpose. Stick welding is usually ...
For this purpose, layered sheets (10, 12, 14) are treated in the other areas (30, 32, 34) in such a way that welding cannot take place. Connection points for lines (72, 74) for feeding in an inert pressurised gas are formed by means of recesses (76, 77) and cut-outs (78, 79...
