We have various certificates for performing semi-automatic welding, which we use mainly for making contour zones and large-scale works. The advantage of semi-automatic welding over electrode welding is speed, flexibility and welding trace.
In this method of welding, the electrode is a welding wire, which is melted in an arc flame created between the wire and the surface to be welded, and the molten metal is transferred inside it to the surface to create a weld. The welding process takes place in a shielding gas environment, which prevents gases in the surrounding air from coming into contact with the arc flame, thus creating the necessary environment for a high-quality weld. If necessary, shielding gas also participates in the welding process.
The name of semi-automatic welding comes from the fact that the electrode or wire is fed using a mechanism, i.e. automatically. However, moving the welding torch or welding gun remains the task of the human hand, i.e. non-automatic
