What is Macrographic Testing?

Macrographic Testing is a destructive metallurgical method used to examine the internal features of a weld. It involves sectioning a sample, polishing the cross-section, and etching the surface to reveal:

• Weld geometry — bead shape, reinforcement, throat size, bead sequence
• Penetration — depth of root penetration and fusion
• Fusion quality — whether the weld fused properly to the base metal and between passes
• Heat‑affected zone — width and characteristics
• Internal defects — porosity, cracks, slag inclusions, lack of fusion, lack of penetration, undercut, overlap
