Welding gauge WG-1/WG-2

Welding gauge WG-1/WG-2

Welding gauge that is actively used in welding processes.
· Ideal for speeding up welding work and streamlining quality control.
· Rugged and light for convenient carrying. (with vinyl case)
· Easy to check because the graduations are on the same plane.
· Includes a pass chart for inspections.
· Measures the size, angle, etc. of weld overlay and fillet.


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.
