Attached are some information on the reheat cracking of Cr-Mo-V steel welds.
In 2008,this issue was very prevalent. To the best of my knowledge it was
with one specific type of SAW Flux-Wire combinations from certain
manufactures which caused this problem.
Subsequently the following presentations were made in various API forums. I
hope this information would benefit the forum members.API introduced an
appendix on NDE methods for detection of such cracks in RP-934(a draft copy
of this appendix is attached)
There are more information available on the web on reheat cracking, however
they are some company specific, and may not be posted without the presenters
permission.
It would be good to hear from welding consumable manufacturers' on this
cracking issue.
Thanks

Subject: [Norton AntiSpam] [MW:3849] Reheat cracking in Cr-Mo-V steel welds
with SAW welding
Dear All,
Pl.share your knowledge and know-how this new phenomenon of cracking
occurring mainly in highly restrained high thick welds of SAW weld process.
The reasons for this reheat cracking and detection by various NDT methods
can be matter of interest for the forum.
