Welding Gauges
The Multi-Weld Gauge for hi-lo, gap, fillet size, weld height, undercut, misalignment and bevel angle.

Western introduced the Multi-Weld Gauge in May 2013 at the Offshore Technology Conference in Houston. One gauge gives easy-to-read measurements of internal hi-lo, gap, fillet weld height and leg length, weld height, undercut depth, misalignment and angle of preparation, on three separate scales — metric, thousandths of an inch and fractions of an inch — with linear rules along the top and bottom of the front face.
Half-circle diameter comparators from 1/16 in to 1/2 in (1.6 to 12.7 mm) give quick estimates of fillet welds and welding rod or wire diameter. For a pocket gauge that also measures pit depth, the Tri-Gauge and Jr. Tri-Gauge lever gauges cover undercut depth and crown height as well.
