Curious to know the application of these castings?
ASTM E165 (Liquid Penetration examination)and ASME Sec Viii Div 1 App 7 outlines the method and
acceptance criteria of discontinuities.
If discontinuity is unacceptable, weld repair shall be performed in accordance with applicable
ASTM, castings shall be PWHT'd for major repairs in accordance with supplementary requirement
S33.
ASME Sec ix and ASTM A488 shall be followed for welding procedure qualification of repairs,
please check client specification for impact requirements or tell us what is MDMT to decide
impact testing,Absorbed energy shall be 48J average and 36J single value minimum. after repair
welding hardness shall not exceed HRC 32 or HV 319.
Surface finish shall be White Pickled
Matched fillers with GTAW and shielding gas Ar + 2% Nitrogen are used for welding repairs if
PWHT is carried out.
Suggest to consult Filler supplier to achieve best results.
