Undercutting is a defect that appearsas a groove in the parent metal directly a;ong the edges of the weld it is most common in lap fillet welds, but can also be encountered in fillet and butt joints. This type of defect is most commonly caused by improper welding parameters, particularly the travel speed and arc voltage Including: HJC60 Universal Welding gauge HJC40 Universal welding gauge HJC40B welding gauge Bridge cam welding gauge Fillet welding gauge (metric) Fillet welding gauge(Metric and inch) Pipe Pit Gauge Selctor welding gaug HI-lo welding gauge Single purpose hi-lo welding gauge automatic weld size welding gauge V-Wac Welding gaue Taper welding gauge 0-15mm Taper welding gauge 15-30mm Taper welding gauge 30-45mm Skew-T Fillet Welding Gauge We export to Belarus,Bangladesh, Belgium, Bolivia, Brazil, Canada ,Chile,Colombia,Czech Republic, Dominica Rep, Ecuador, Finland, Hungary,
