🔥 Welding & Heat Treatment

Weldabilityeasy

Preheat Requirements

10°C min; preheat required for heavy wall thickness per ASME B31.3.

PWHT Requirements

Required if nominal wall thickness t > 19mm (0.75 in) per ASME B31.3 Table 331.1.1.

Charpy Impact Test (CVN)

Exempt down to -29°C (-20°F) per B31.3 Fig 323.2.2A. Impact test required if MDMT is lower.
