Ive got myself all worked up over this issue. I'm filling out a welders qualification record and I'm not certain of the "Qualification Range" of this test.
Does one fillet weld test on 1/2" steel plate (A572) in the 2F position (Figure 4.37, pg 184) qualify a welder to weld a pipe over 24" in diameter?
I am using D1.1 2006, table's:
Table 4.10 (pg 145)Welder Qualification -Production Welding Positions Qualified by Plate Test.
Table 4.11 (pg146) Welder Qualification- Number and type of Specimens and Range of Thickness and Diam. Qualified.
I see in Table 4.10 that a Qual. Test w/ Plate and fillet weld in the 2F position gets me :
Production Plate- Fillet in F and H
Production Pipe- Fillet in F and H
Production Box Tube-Fillet in F and H
No footnotes apply for Table 4.10
Table 4.11 (1) Test on Plate, halfway down the page Fillet option 1 (fig 4.37) **note the AWS Errata sheet that they admitted a misprint in this table.
Fillet option 1, 1/2" plate 1 fillet weld break test, 1 macro etch, qualifies for plate thickness 1/8" to unlimited 60 degree to 135.
Here's my issue/ question. Look on pg 147 the continued table 4.11 (2) test on pipe, almost halfway down, option 1 fillet figure 4.37 footnote G.
Footnote G states "Two plates required, each subject to the test specimen requirements described. One plate shall be welded in the 3F position and the other in the 4F position."
I only gave one test in the 2F position on plate, isn't this telling me he's not certified for production welding on pipe min. 24" to unlimited because I need to give two tests, one each in the 3F and 4F position.
Could someone please straighten me out on what I am misinterpreting on the pipe fillet weld and pipe Dia. size.
Thank You , Chris
