GB/T 35085-2018 specifies the test method of Vickers and Knoop Hardness for laser and electron beam welded joints in metal materials. The standard describes the test principle, specifies the requirements for the accuracy of the test equipment, and specifies the preparatory specifications for welded joint samples, covering cutting, sanding, polishing and other steps. At the same time, the test process of Vickers and Knoop Hardness is standardized, including the selection of test force, loading time and Measuring location determination. With this standard, the specific area Hardness of the welded joint can be accurately measured, providing key data support for evaluating the welding mass and optimizing the welding process.
