Thanks in advance..
Can guide me the detail way of PQR procedure for welding SA240 TP304 stainless steel 1.2mm thickness and procedure for selection of suitable filler metals.
Note : as per MTC, SS 304 - T.S=587MPa, Cr=19 6 & Ni=9.63
what are all the essential variables we considered during PQR?
Is purging essential for the above PQR? If it is not done what problem and effects occurs during testing.
What type of mechanical testing is applicable or essential for the same. (Note: because of our job is non pressure parts (ie) industrial silencer. That butt weld occurs in perforated sheet joint which is placed internal in silencer.
Kindly send the solution as soon as possible.
Thanks & regards
