Welding issues after heat treatment
Thread Content
There is a piece of equipment on site; the material used is 14Cr1MoR with a thickness of 130 mm. It has already been delivered to the site. The manufacturer failed to weld the pre-welded parts. I would like to ask what considerations need to be taken into account regarding the welding process and heat treatment process for welding such equipment’s pre-welded parts
Preheat before welding, and carry out heat treatment immediately after welding; the specific procedures can be followed as specified in the design documents or welding standards Nbt 47014 and 47015
Preheating, inspection, welding, post-heat treatment, non-destructive testing
This works too. . . This manufacturing plant is really amazing. . . The first two points mentioned are quite correct.
