Mig Welding Process Diagram. Characteristics of the mig welding process. Hold the mig gun at a 90 degree angle to each piece of metal when welding a butt joint to direct the heat and filler metal equally to each piece of material.
The third is a handle with a trigger that controls the wire feeder that feeds the wire from a spool to the weld joint. Mig welding is generally regarded as one of the easiest type of welding to learn. In this welding a thin wire acts as the electrode which is fed from a spool mounted on a gun through a flexible tube and it comes out of the nozzle on the welding gun or torch.
Mig welding is an automatic or semiautomatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is.
This welding is same as tig welding except a non consumable electrode replaced by consumable electrode wire. Mig welding is generally regarded as one of the easiest type of welding to learn. In this welding a thin wire acts as the electrode which is fed from a spool mounted on a gun through a flexible tube and it comes out of the nozzle on the welding gun or torch. Simultaneous melting of the flux coating on the rod will form gas and slag which protects the weld pool from the.
