Re: [MW:13487] amendment for this WPS regarding

if u have not done preheat in ur PQR, revise ur wps to mention minimum
preheat temp. As far as interpass temp, since it is not call for
impact test, u need not mentioned interpass temp in WPS. Since ur
using SS filler it is always better to mentioned interpass max to
avoid mettallurgucal changes in weld metal
thanks
