The hardness is determined by measuring the depth of indenter penetration or by measuring the size of the impression left by an indenter. Hardness tests that measure the depth of .The qualification of welding procedures is necessary to ensure that the selected welding parameters can produce sound welds. Qualification typically involves a combination of destructive and nondestructive testing. When a particular code, such as AWS D1.1 or ASME Section IX is used, the code will dictate the type and numbers of tests necessary in order [.]Our simple and easy-to-use high-resolution digital camera equipment delivers fast results for weld testing and structure verification. Non-Destructive Testing. . The Vickers hardness test is a versatile hardness test method, used for both macro and micro hardness testing. It has a broad load range, and is suitable for a wide range of .
The test is performed by welding a test coupon, which is then subjected to various tests (such as tension, bend, and Charpy impact) to determine the weld’s mechanical properties. If the test results meet the requirements specified in ASME Section IX or AWS D1.1 , then the welding procedure can be qualified for use in manufacturing.Each hardness test varies by method; however, the procedures all remain relatively similar. A weld hardness test is performed by mechanically pressing a specifically dimensioned object, known as an indenter, onto the weld. Hardness is then determined by measuring the penetration or size of the impression left by the indenter. Hardness testing of weld overlay procedure test as per ISO 15156-2.
