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...
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...
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...
weldstan, Duwe6,
Thank you both for some very sound advice. I firmly agree that ASME IX needs to change with the times, and also be written in a more user friendly manner.
SectionIX (Petroleum),
Thank you for the concise explanation it is very much appreciated.

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. I just can't get my head around what the ASME IX code is stating.
As I am quite a new person to the code, Could one of...
david339933, metengr & Section IX,......Your answers have clarified the situation perfectly. Thank you all so much for your help with this. It is very much appreciated.

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...
Hello Everyone, this is my first post using Eng Tips, having been a regular visitor to find solutions to problems for quite some time.
I have a question that no doubt you ASME experts have answered on many occasions, but I can't seem to find a definitive answer anywhere, so I have joined the...
