Arc welder and its significance

Arc welding is commonly used because of the low cost and is normally the first type of welding apprentices learn. Arc welding uses an electrical current between an electrode and the welding material to melt the metal and create the weld. The area being welded is sometimes protected by semi-inert gas or filler material. Arc welding is a simple welding method that can be used by almost any weldor, and it can be used on nearly any type of metal. There are more technologically advanced methods of welding, but arc welding is easiest and to perform arc welding, arc welder is used.

Multi-wire Submerged Arc Welding Process of Longitudinally Welded Pipe

Because the multi-wire submerged arc welding of longitudinally welded pipes has the characteristics of large undercooling and fast welding speed, the equilibrium state is basically eliminated. If the same chemical composition as the base metal is used as the welding material, the weld metal will have low plasticity, Low toughness, high strength mechanical properties.
