bolt hole thru weld
bolt hole thru weld
(OP)
Have a condition where a steel fabricator was permitted to CJP weld a continuous member and because of some changes a connecting beam now requires bolt holes directly thru the weld. Is this prohibited in the code? It's a relatively light connection so my gut reaction is that it would be fine but I've told them that there may be some issues trying to drill a weld.
Any input is appreciated.

I am not sure of the specifics of the code. Once a CJP weld is done, it is as good as the member. But I don't know if it the same thing as drilling a hole through a member vs. drilling it through weld metal. Do we have to worry about stress risers etc.? I am not sure.

You must also verify that the location of the hole does not cause other issues. Net capacity, residual stresses, etc

However, burned holes are technically allowed. If necessary, I recommend burning a smaller hole and reaming to the required diameter.
