v: to join metals by utilising the arc created between the welding rod, which serves as an electrode, and a metal object. The arc is a discharge of electric current across an air gap. The high temperature generated by the arc melts both the electrode and the metal, which fuse.

n: a welding technique for joining pipe ends. Two general types of automatic welding used in pipeline construction are submerged-arc welding and automatic wire welding.

n: an automatic welding process utilizing a continuous wire feed and a shielding medium of fusible granular flux. Submerged-arc welding offers high deposition rates and weld passes of substantial thickness.
