As an alloy steel or mild steel is described, which has a special quality, for example, are steel, the so-called Eisengebleiter sulfur and phosphorus below 0.025%. The stainless steel welding can be done with almost all known welding methods, most often, however, the TIG welding, MIG, MAG and the e-welding. In TIG welding burns, an electric arc between an electrode and the workpiece.

The electrode is surrounded by a jet emanating from the inert gas that protects the arc and the weld before the outside air. If a welding additive is required, it will be fed manually or mechanically. When welding stainless steel is welded with DC, with the lying on the negative electrode is polished acute course.

In MIG and MAG welding are also on fire, an electric arc between the electrode and workpiece, but this melts the electrode. Thus, it is simultaneously energized electrode and welding additive. The electrode is automatically fed, where it is surrounded by a nozzle, emerges from the protective gas. When MIG welding is helium, nitrogen or argon, so inert gases.

In MAG welding, the noble gases, carbon dioxide or oxygen is added, resulting in active gas, which reacts with the active materials. Another way to to weld stainless steel, is the e-welding. These are designed to guide such that an electric arc burns between the workpiece and a consumable electrode.

The electrode is surrounded by it and the melting of the cladding forming gas and a slag. The gases protection, comparable to the inert gas to MIG, MAG and TIG welding the arc and the weld, the slag binds impurities, causes a slow, steady cooling, thus ensuring little welding distortion. After cooling, the slag is removed. In addition, the e-welding provides a further advantage provided by the compact, portable welding machines: the welding work can be carried outdoors and even in the wind.
