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.
