Make sure the pipe is held in place with spacers or a jig so it is actually
centered on the hole before welding, otherwise you could end up with fillet
welds that don't have the leg length you assumed at the web.

Subject: Web Openings in Structural Steel
Are there any special procedures that should be followed when cutting
circular openings in the webs ? I have an existing W33x130 that will have a
8 inch diameter hole field burned. The hole will be reinforced with a 3"
long piece of pipe that is to be snug fit in the hole and fillet welded to
the web on both sides. Does the cut surface have to be ground smooth for
example ? I'm using AISC Steel Design Guide #2 for design check.
Thanks for any comments.
