Our certified weld inspectors (CWIs), SNT-TC-1A certified technicians, professional engineers, metallurgists, and chemists provide high-quality weld inspection and testing services to clients from numerous industries. We offer tests according to ASME, AWS, MIL-STD, API, and NAVSEA standards, depending on the client’s specific needs.
The Cut and Etch Test
The cut and etch test is a mechanical procedure for evaluating weld quality. Testing experts cut a sample from the weld coupon transversely to the weld axis. Experts then grind and polish the sample’s cut face before etching the surface with a chemical reagent. Etching the metal defines the boundaries between the base metal, weld metal, and HAZ (heat-affected zone). This process also reveals the sample’s microstructure and flow lines. The cut and etch test allows weld inspectors to thoroughly evaluate a weld for penetration fusion, defects, and other material characteristics. The data we collect assists clients with several applications, including weld procedure qualification, routine quality checks, failure analyses, welder qualification testing, and others.
