Data for WPS

Date 11-03-2004 10:26

I am looking for data to fill my WPS for QW-406 to QW-410 requirements for corrosion resistant overlay of SA-216 Grade WCC using filler metal ER316L but it seems that ASME Section IX do not have the information I need, I looked ASME Section II Part C but I found nothing can you help me?

Hi
Assume that you are using GMAW or FCAW for overlay welding. In ASME
Section IX, QW-404 does address essential variables for filler metal, QW-404.23, 404.24, and 404.37.
QW-406.4 decrease preheat greater than 100F and preheat exceed interpass temperature are essential variables.
QW-407.6, changed PWHT is essential variable.
QW-409.4, change current or polarity is essentail variable.
QW-409.26, heat input more than 10% is essential variable.
QW-410.38, changed multi-tp single -layer is essential variable.
QW-410.50, changed number of electrods is essential variable.
QW-410.51, the addition or elimination of oscillation of the electrode or electrodes.
Kind regards
