MMA-Schweißnähte 

MMA (Metall-Lichtbogenhandschweißen) oder Rodgenschweißen. In MMA welding, an arc is generated between the electrode and the metal to be joined. Dies geschieht durch einen elektrischen Shortschluss. Due to the simplicity of the equipment and the way of working, MMA welding is one of the first and most popular welding methods in the world. Es dominiert andere Schweissverfahren in der Wartungs- und Reparaturindustrie. The process is mainly used for welding iron and steel (einschließlich rostfreiem Stahl), but aluminum, nickel and copper alloys can be welded with this process.
