Hi Lo Weld Gauge

The hi-lo weld gauge is an essential internal misalignment inspection tool used extensively in pipe fitting, pressure vessel fabrication, and shipbuilding. Crafted from durable stainless steel, this manual tool measures the inside mismatch or alignment of two pipes or plates prior to welding, helping to prevent structural joint failures.

By inserting the gauge's prongs into a pipe gap and adjusting its body, inspectors can read internal misalignment in both inches and metric units. Beyond checking alignment, a standard hi-lo gauge also measures root weld space gaps, prep bevel angles, crown reinforcement heights, and fillet weld leg lengths.
