[MW:24816] Re: WPS and PQR for overlay

Dear

As per ASME Sec. IX, Table QW-453 there are two types of Overlay (1) Corrosion Resistance (2) Hard Facing. So, 1st you decide types of  Overlay and then follow notes no given in Table QW 453.

i am preparing WPS and PQR for overlay for the first time. i have checked ASMEIX QW-453. it just confused me!!!!

actually we are finding which materials is the most suitable one for overlaying. the base metal is  A216 WCB and the overlay are 

stellite, monel, F316 and 13%Cr. 

i read that the dimentions of base metal should be 15*15 cm, with 2.5cm thickness. which examinations should be done on samples to prepare PQR? PT, chemical analysis, hardness nad macro? are these enough?

can somebody send me a sample of PQR and WPS for overlay please.

best regards

sara
