That is weird, Fig 4.20 is a procedure qualification, and table 4.11 is about performance qualification. All of the other figures that table 4.11 references are clearly labeled welder or welding operator qual tests. But sure enough, 4.11 appears to allow the use of Fig 4.20 and a single macro, 4.31.4 says you need a break test. If you look at the rules for the macroremoval 4.31.2.1(2), they only talk about the macros for Fig 4.37.
I wonder if 4.20 is an error in the table?
Hi Bubba
The tests required are given in Table 4.11. (As referenced from 4.20.1.) The details as to how the tests are to be performed are given in 4.31.4 in the case of fillet weld break tests. It is not the intention of 4.31.4 to require all fillet welds to be given these particular tests. (This is also clear from the first paragraph of 4.20.1.)
Why figure 4.20 is labelled as only procedure qualification, and not also performance qualification, or if the reference to 4.20 is incorrect, would be another debate. Seeing as these requirements are the same in both the 2008 and 2010 editions of the code, it is probably not an error.
