Tensile Properties and HAZ Definition for TIG and EB Welds Using Electronic Speckle Pattern Interferometry (ESPI)

Abstract:

Article Preview

Electronic Speckle Pattern Interferometry (ESPI) is used in conjunction with a mechanical test rig to determine the tensile property response when loading cross weld tensile samples of Tungsten Inert Gas (TIG) and Electron Beam (EB) welded Inco718, which include the parent metal, Heat Affected Zone (HAZ) and weld metal. A comparison with cross weld micro hardness testing revealed that such results were misleading when compared with ESPI calculated Proof Stress (PS) variations across the weld region from the same specimens. The effects of ignoring weld related material property variations when modelling welded components are examined.
