ASME IX Thickness range question
David 339933, I can understand your confusion. Your view seems to make sense, and I often find myself bewildered by the codes and the interpretations, which sometimes contradict what's written or don't appear to make sense. There is another interpretation in the B31.3 code, however that further...- DeanIEng

ASME IX Thickness range question
DekDee, Thanks for helping. Your comment does muddy the water somewhat. How is it possible that the original WPS may cover 0.337"? Is it A-5 in Table 323.3.1 which would qualify the thickness range as 0.216" - 0.668" (5.43 - 17.3mm)?. Also, are there any other "minor revisions" that...- DeanIEng

ASME IX Thickness range question
Hello one and all, I have a question regarding the ASME IX code. A procedure is qualified by welding a 6" Sch 80 pipe, wall thickness 0.432" (10.97mm). As the procedure will be used for a pressure application, notch toughness testing is required. QW 403.6 applies in this...- DeanIEng

Welders range of base materials qualified
SectionIX (Petroleum), Thank you for the concise explanation it is very much appreciated. When I viewed table QW 423.1, I wasn't sure whether it meant that if you qualified with a P1 for example in the left hand column, that you then qualified only for the same P number in the right hand...- DeanIEng

Welders range of base materials qualified
thread292-94927 I have read through the above referenced thread and a few others, to try and get an understanding of the range of base materials the welder can qualify for.

ASME IX Procedure versus Performance thickness ranges
Ok, thank you for that. So if a base metal of say 10mm (3/8") was used, the procedure range would be 4.8mm (3/16") to 20mm without impacts, and 10 - 20mm with impacts? Now here is where is where I get confused; The weld metal thickness qualified in the procedure according to 451.1 is 2t, But...- DeanIEng
