Weld Question
(OP)
I have a problem at a weld connection (gravity column to cap plate). The cap plate was 1" thick. The HSS column had a 1/2" thickness. The weld specified was 5/16" (code minimum). The contractor used a 1/4" weld. Is that fine or should I ask him to redo the weld.






RE: Weld Question
If 1/4" works for strength, I'd be inclined to leave it be.

RE: Weld Question
This maybe a theoretical question, why is there a minimum size of weld for a particular thickness. Does a smaller weld fail when connecting two thicker parts?
RE: Weld Question
It is a requirement based on the quenching effect of a thick piece of metal (even though the requirement is based on the thinner piece being joined).
A thick piece of metal rapidly conducts heat away from the weld, leading to rapid cooling which results in a loss of ductility.
