Advanced Welding Material Selection & Compatibility Matrix
A comprehensive guide for matching base metals, filler materials, and welding conditions.
This matrix is tailored for Welding Engineers, Inspectors, and Trainers to ensure proper material compatibility and process selection.
Pro Tips:
A. Always match filler metal chemistry with joint performance needs (strength, ductility, corrosion).
B. Refer to WPS, PQR & MTCs before executing any joint.
C. Strictly monitor interpass temperature and cooling rate – especially for crack-sensitive materials.
D. Cleanliness, fit-up, and joint preparation are critical to avoid defects.
