Your boss sounds like he is not in business for the long haul. He may or may not wiggle his way through the job by claiming he is welding to a standard he has not even read. But, the customer's bad experience will make him go elsewhere on the next order. We have this same problem with metal products from some foreign manufacturers that claim their pipe meets an ASTM standard even though they don't have a copy and can't tell you what the requirements are. You might want to talk to your local AWS chapter and review the copy in their technical library. You will need to prepare written welding procedures, qualify the welders, meet the workmanship requirements, minimum weld size requirements, meet the weld acceptance criteria, etc., etc., etc. There's a lot of requirements that need to be addressed and unless you have a copy available there's no way to know what they all are.
Good Luck
