The Macro Etch Weld Test

The macro etch weld test is one of many weld testing services that Applied Technical Services performs. ATS employs certified weld inspectors, metallurgists, professional engineers, and SNT-TC-1A certified technicians who can provide high-quality weld testing services. We offer testing in accordance with AWS, ASME, API, NAVSEA, and MIL-STD codes and standards, depending on each client’s specific needs.
Macro Etching
Macro etch testing is a mechanical procedure for assessing weld quality. Testing experts perform macro etching on cross-sections removed from weld samples transverse to the weld axis. Inspectors grind and polish the samples, etching the surface of the cross-section with a chemical reagent. This process distinguishes the base metal, heat-affected zone (HAZ), and weld areas for examination while also exposing the material’s flow lines and microstructure. Macro etching allows inspectors to check for numerous weld properties and defects, including porosity, lack of penetration, discontinuities, lack of sidewall fusion, weld size, weld profile, and other structural elements and material characteristics.
The data collected from macro etch weld testing offers benefits for several applications. This test can assist with routine quality checks, welder qualification testing, weld procedure qualifications, and failure analyses, among other functions.
