Hardness Testing For Welded Parts: What QC Labs Should Check Before Delivery
Welded parts require hardness testing before delivery to verify weld metal, heat-affected zone, base metal, post-weld heat treatment results, and potential brittle or softened areas. A reliable QC process should include correct test method selection, sample preparation, Vickers or Micro Vickers test path planning, calibration verification, and clear inspection reports.
