A group of joining processes that produces joining of base materials by heating to the soldering temperature and using a filler metal with a liquidus not exceeding 450°C (840°F) and below the solidus of the base materials. When soldering, the base material is not melted.

Shield Metal Arc Welding (SMAW)

A widely used arc welding process in which coalescence of metals is produced by heat from an electric arc that is maintained between the tip of a covered (flux) electrode and the base metal surface.  The process is considered manual with hundreds of applications such as structural steel fabrication, pressure vessels, storage tanks and maintenance / repair.  SMAW is commonly used to weld carbon / stainless steel alloys, cast irons, copper, nickel and some aluminum in all positions.  SMAW is a portable process with eye, skin and face protection required.

  • The following welding and management definitions may be useful when making choices for welding complianceWelding is a process that produces coalescence of materials by heating them to the welding temperature, with or without the application of pressure or by the application of pressure alone, and with or without the use of filler metal. Welding occurs when the temperature exceeds the melting temperature of the base metals.
