GB/T 39082-2020 specifies the Vickers Hardness test method for resistance point welding, projection welding and seam welding joints. It clarifies the test principle, puts forward requirements for the accuracy of test equipment, etc., and details the preparatory process of welded joint samples, including cutting, sanding, and polishing steps. Standardize the Vickers hardness testing process, covering the selection of test force, loading time, and Measuring location determination. According to this standard, the Vickers Hardness of welded joints can be accurately measured, providing key data for evaluating welding mass and optimizing welding process, and promoting the reliable application of resistance welding technology in various industries.
