Electrode Welding: What is it & How To Choose? (with Chart ...

Electrode welding works off of this constant current (CC) by short-circuiting between a flux-covered electrode held in the stinger and the workpiece. This creates an electrical arc that generates heat to melt the workpiece and the electrode simultaneously. The electrode melts to deposit filler metal into the weld pool (the puddle of molten ...

What is an arc and how does arc welding work?

A distinction is made between various arc welding processes: Arc welding with a consumable electrode. Gas metal arc welding (GMAW) uses a gas that prevents the molten metal from reacting with the atmosphere.The name given to the welding process depends on the type of gas used, which may be inert, such as helium, argon or a mixture of both, or active, for example CO 2.
