    Failure in Bend Test-Combination Process GTAW+GMAW As per ASME Sec.IX-Procedure Qualification

    Nace mr0175 hardness survey

    In regards to NACE MR0175 (sour service) does clause 7.3.3.4 apply in all cases? In other words must I ALWAYS hardness test production welds or "sample coupons" when sour service is applicable? I have reviewed a few posts on this subject on this site which give bewildering replies. If I am...
