NIIGATASEIKI

Caution

Product Description

Convenient welding gauge that enables dimension measurement of weld overlay, fillet, leg length, etc. all in one.
[Features]
· The silver finish reduces reflection when taking photographs.
· Suitable 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.
· Undercut measurement is also possible.
· Maintains a sense of stability during measurement through enhanced base thickness.
[Applications]
· For measurement of 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.

Instructions for inspection

	3.	Unevenness on welding bead surface
	4.	Under-cut
	5.	Overlap		Visual inspection
	6.	Size of corner buds (Lack of throat thickness • foot length of fillet)
	7.	Excessive buds from groove welding
Others	8.	Arc strike		Visual inspection
