316L SS WELD CRACKING
316L SS WELD CRACKING
(OP)
We take a small triangular bar and weld either round rod or flat bar material to it. When using the round rod the welds look good but when using the flat bar we are getting cracking. This appears to be a problem with the flat bar. We have had test done on the 316L material and everything checks ok. All metals being used are 316L ss material and fusion welded using no filler material. Does anyone have any suggestions where to start looking as a possible cause. I have more information on the problem if someone has any ideas.





RE: 316L SS WELD CRACKING
The flat bar may cause localized cooling to the weld, as the round rod may be less prone to it.
The cooling of the weld should be controlled if possible in order to avoid intergranular corrosion, since 316L contains quite high amount of Cr.

Come back with a little more description of the joint, sizes and configuration.
Where is the weld cracking?
Can you add filler metal?
