Arc welding is a fusion welding process that uses an electric arc to create heat to melt and join metals. A continuous electric current flows between an electrode and the base material, creating an arc. This arc generates intense heat, typically reaching temperatures of 6,000 degrees Fahrenheit or higher, which melts the metals at the point of contact. Filler material is often added to the joint to reinforce and strengthen the weld.

There are several common types of arc welding. Shielded metal arc welding (SMAW), also known as stick welding, uses a consumable electrode coated in flux. Gas metal arc welding (GMAW), or MIG welding, uses a continuous wire electrode fed through a welding gun, and a shielding gas is used to protect the weld pool from contamination. Gas tungsten arc welding (GTAW), or TIG welding, uses a non-consumable tungsten electrode and a separate filler rod is fed into the weld pool. Flux-cored arc welding (FCAW) is similar to MIG welding but uses a tubular electrode filled with flux.

Arc welding is used in a wide variety of industries, including construction, manufacturing, automotive repair, and shipbuilding. It is a versatile process capable of joining a broad range of metals, including steel, aluminum, and stainless steel. The quality of an arc weld depends on factors such as the welding technique, the type of electrode used, and the proper shielding of the weld pool. Safety is paramount when arc welding, and proper personal protective equipment, such as welding helmets, gloves, and flame-resistant clothing, should always be used.
