The company performing the welding or the people who hire the welders should have a written welding procedure (for all joints to be welded) submitted to the engineer of record on that project for approval, before any welding is allowed to take place. Then the welders will work from that approved WPS.
As for whether I have any approved procedures......I have many welding procedures written and they get submitted before the start of any job and approved, but they belong to the company that I work for.
If we knew a bit more about the relation you have with the anchors that need to be welded we could help guide you better. Are you the erector, the general contractor, architech, engineer, or what?....
I work as a QA/QC manager for a structural fabricator and our company deals with many phases of steel construction from the anchor bolts to the roof deck, so maybe I can help if I knew more about your situation and who the players are(no need to name anyone...just their function...erector, contract welder, etc....)
