What is welding gauge

Welding gauge is used to measure and check size of welded part throat
thickness required strength split that may casue damage irregularity of
under-cut and overlap etc.

Terms of welding

  • Throat thickness
    The thickness from welded portion at triangular cross-section when welding two faces at 90°.
  • Arc strike
    The arc that occurred to parts other than welding base metal when working on arc welding.
  • Pit
    Blow hole on surface due to poor welding.
  • Bead
    A belt shape rises after working on welding.
  • Under-Cut
    The irregular groove at the toe of a rod in the welding base metal.
  • Overlap
    The heap results from miss welding of the base metal.
