There are several types of welding including MIG, TIG, Stick, Flux-Cored, and Submerged Arc Welding.

• MIG (Metal Inert Gas) welding uses a wire electrode and a shielding gas to join two metal pieces together.

• TIG (Tungsten Inert Gas) welding uses a tungsten electrode and a filler metal to create a strong bond between two metal pieces.

• Stick welding, also known as Shielded Metal Arc Welding (SMAW), uses a consumable electrode coated in flux to create an arc that melts the metal pi...read more
