The FIT-UP PRO Q.C. Welder’s Gauge with Pit Depth attachment is a precision tool designed to streamline weld inspection and quality control. Built to measure internal misalignment (high-low), external mismatch, and pit depths, it supports both pre- and post-weld evaluations. It delivers highly accurate readings in 1/64″ / 0.4 mm increments, helping welders avoid costly rework and ensuring compliance with strict fabrication standards. The optional stainless steel pit depth gauge enhances functionality, enabling precise measurement of weld crown height, undercut, and corrosion pits. Constructed for durability, the gauge is suited for rugged field conditions while remaining easy to use. Available in both imperial and metric versions, it comes packaged individually or in boxes of ten. Lightweight and compact, this tool is a go-to solution for welders aiming for consistency, reliability, and accuracy during critical inspection phases. Whether in-shop or on-site, it boosts productivity and minimizes the risk of weld rejection.
