The Fit-Up Pro Q.C. Welder's Gauge by Mathey Dearman is an essential tool for welders and fabricators, designed to provide fast and precise measurements of internal 'High-Low' and plate mismatch both before and after welding. This capability significantly minimizes costly rework and weld rejections, ensuring higher quality outcomes. This rugged Imperial model is specifically engineered for measurements in inches, offering precision down to 1/64 inch (0.4 mm) increments. It is a versatile tool, also available in Metric models to suit various global standards. The gauge features a clear indicator and a precision scale for accurate readings. An optional stainless steel pit depth gauge attachment further enhances its utility, allowing for accurate measurement of pit depth, weld crown height, and external misalignment. This comprehensive functionality improves overall inspection quality and weld consistency. Built for durability and ease of use, the Q.C. Welder's Gauge is the professional's choice for reliable weld fit-up evaluation and quality control, whether on-site or in the workshop. Its operation is straightforward: simply slide the pit depth gauge over the Q.C. Gauge to take a reading.
