welding A297 HD with AISI 1020
(OP)
hi all
anyone here can help me in this problem:
i have to join by GMAW a pipe material: ASTM A297 HD also DIN: GX40CrNiSi27-4 also UNS: J93005 with AISI 1020 carbon steel. can anyone tell me
1)wich select filler metals use to jon them
2) preheating temperature?
3) cooling rate?
any help is apprecite
thanks

Filler metal - Inconel 82 or 182
Preheat - 200 deg F
Cool in air
Interpass temperature - 350 deg F max

i do not understand what do you want to day with Ditto metengr.
RE: welding A297 HD with AISI 1020
Filler Metal - Arcaloy 312-16 (E312-16) or OK 68.81 (E312-17)
Preheating would not normally be required
Slow cooling would not normally be required
For a simple flange to pipe weld post weld heat treatment would not normally be necessary
What do you think about?
thanks

It means that I agree with metengr.
RE: welding A297 HD with AISI 1020
I think the nickel base filler metal will provide better service versus the 312 because of the better match in the linear coefficient of expansion between the carbon steel and cast austenitic stainless steel. The preheat is for the carbon steel, not the austenitic stainless steel.
