Welding a pipe involves joining two pipes together in a process called welding. Welding techniques used for pipework include arc welding, as well as MIG or TIG welding, which are both arc welding processes.
1. Shielded Metal Arc Welding (SMAW)The process of shielded metal arc welding (SMAW) can be referred to as Manual Metal Arc Welding (MMA or MMAW), Flux Shielded Arc Welding, or Stick Welding.
– Root Passes: The root passes are the first passes that are required to fill in the gap between the two sections of piping.– Hot Passes: These passes connect the root weld to the groove faces on both sides of the groove.
