The TWI welding gauge (Cambridge gauge) is a multi-purpose welding inspection gauge for checking the dimensions of weld preparations, butt welds, and fillet welds.
Used for checking the angle of preparation (0 – 60°), excess weld metal (cap size), depth of undercut, depth of pitting, fillet weld throat size, fillet weld leg length, and misalignment (high-low).
Other welding gauges are available and we can source many others, contact us for more information.
