Weldability of Inconel 713
Weldability of Inconel 713
(OP)
Hello,
Probably to no ones surprise we are experiencing problems with welding In 713. Cracks are showing up on xray in the heat affected zone (HAZ)for about half the parts we weld. I'm taking it upon myself to fix this problem. My question is are In 713 alloys more suceptible to Strain Age Cracking or Liquidation Cracking. The ASM Welding Handbook suggests that in these alloys Strain Cracking may be more likely, but we are detecting cracks in xray prior to the post-weld stress relieve heat treatment. Thanks for any info.

WELDABILITY OF NI-BASE HEAT RESISTING SUPERALLOY --MAIN CAUSE OF WELD CRACKING IN HEAT AFFECTED ZONE OF INCONEL 713C
isn't free. Does the author suggest some pre-weld heat treatments. I found some heat treaments for IN 738 (Soln at 2100 F for 2 hours and over-age at 1800 F for 20 hours). Could these heat treaments be applied to IN 713C? I realize it is important to get these alloys in the softened condition prior to welding. Thanks for any info.
