The weld testing laboratory at Applied Technical Services utilizes a wide range of hardness testing methods to conduct weld hardness tests. 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. ATS experts have the ability to conduct Brinell, Barcol, Webster, Rockwell, Vickers, Knoop, and Leeb hardness testing methods as necessary to the project scope. All weld hardness tests performed at ATS follow the below industry standards:
