A WPS is a guideline to ensure joint integrity as proven by PQR + applicable mech tests + NDT. It is intended for all job sizes once the welding technique used proves itself in these tests. The sizes etc come in to picture by qualifying welder on test coupons of a given size as per your job requirements. ASME IX stipulates weld metal deposit and not job size. Please ref to QW 450 - 461.
