One or several, job by job. The regime is a layer on the same backbone — not a different product.
UNI EN ISO 9606-1 — Qualification testing of welders — fusion welding — part 1: steels
The international welder qualification standard for steels, adopted in Europe as EN ISO 9606-1. Eight essential variables define what a certificate covers, and the designation string on the certificate encodes all of them.
UNI EN ISO 15614-1 — Welding procedure qualification — arc and gas welding of steels, arc welding of nickel alloys
The procedure test. A weld is made, tested to destruction, and from what it demonstrated a range of qualification is derived — the range being the whole point.
ASME BPVC Section IX — Welding, brazing and fusing qualifications
The American route, and the code most often specified on work outside the European Union — dominant in North America and the Gulf. Procedure and performance qualification through essential, supplementary essential and nonessential variables.
A notified body has the opposite problem to a fabricator: it does not need to get itself compliant, it needs to prove how it made thousands of decisions about everyone else.
