Good morning Ed,
I will try and explain the reasoning behind my opinions of this standard.
WTIA Technical Note 11 Clause A4.12.2 Welders states " All welders must qualify for eachweld procedure to be used on the job by means of a macro test, unless they can demonstrate successful prior experience with that procedure (eg. through NDE records) or are working within the limitations of the qualifications obtained under Clause 4.12.2 (a)."
The clarification from "all" to "each" makes a huge difference.
Yes it is ridiculous to do it as you have stated but I think the standard is quite clear, if you don't have prior qualifications you must do a macro for "each" procedure to be used.
With regard to prior qualifications the Clause noted above states " In all cases , welders with these qualifications, and those specifically listed in this clause, are deemed to comply only whilst working within the limitations of their original qualification (note especially the limitations within AS 2980)
That means that if you are submitting an alternative qualification (eg. AS/NZS 3992, AS 2980, ASME IX, EN 287 Pt 1, AWS D1.1, ISO 9606-1) you must comply with the thickness tolerances nominated in those codes.
AS 1796 and NZS 4711 both have extensive training and qualification requirements but no thickness limitations as far as I am aware of. However, they would still have to qualify with the AS/NZS 1554 WPS thickness requirements.
I could waffle on for hours about the anomalies in this standard but I think I would be shot down very quickly by welders in the UK who don't give a toss about AS/NZS 1554.
I just wanted to clarify my disagreement to your statement that there was no thickness limitations for welder quals.
