See Paragraph 3.9 which refers to figure 2.1 and para 2.4.5 in D1.1 98. These paragraphs may differ in 2002 D1.1.

In the 2002 D1.1 it's para. 3.9, Table 3.7, Figures 2.1, 2.15, 3.2 & 2.5.
I realize doing a WPS saves time and money, but a fillet weld test isn't that big of a deal either. Off the top of my head , it amounts to a T joint with a single pass of the max size fillet on one side and min multiple pass size fillet used in construction on other side.
See Figure 4.19.
Hope this helps

Fillet welds as a joint configuration are prequalified and do not require testing to write a procedure. Essentially you have big ones, small ones, straight ones and skewed ones but fillets are pretty much the same otherwise. The references to section 2 are primarily for design concerns and as such are more of a concern for the people who are specifying the weld size.
You will need to review D1.1 to make sure you are in compliance with prequalification provisions but writing the WPS is fairly easy. Make sure the parameters, shielding gas(if applicable) and so forth are within manufacturer's recommendations and put them on your procedure along with a sketch of the weld joint. It would be a good idea to make weld mock-ups so you know what you are writing down can actually be done but you shouldn't have a lot of difficulty with it.

This is only a suggestion, so please take it as such. If you go ahead and test a welder in a 2G (horizontal)position and they pass, then the welder will be qualified for 1F and 2F position fillet welds automatically along with 1G and 2G position groove welds. Plus it covers him/her on 24" diam. pipe and greater. If you use 1" thick plate for the coupon then they will be qualified for 1/8" to unlimited thicknesses as well. All of this would be prequalified and that means no testing of WPS's, only welders. Saves $$$$$'s. Most all shop work can be done in the flat or horizontal positions by turning the work piece to acheive the proper positions for welding. If the piece is so large or for some reason that it can't be turned then you have no choice but to qualify in those positions as well.
Hope this will help,

John,
As I reviewed proformance qualification, positions qualified,D1.1. A fillet welded 2F, qualifies the welder for 1F & 2F. It does not automatically qualify the welder for 1G & 2G.
Now a 2G qualifies for 1F,2F & 1G. It that what you meant?
Lew
Hi Lew,
Yeah, that's what I was trying to convey :)
(2G test coupon to qualify for 1F,2F,1G,2G and Pipe 24"OD & greater OD).
Sorry for the poorly worded reply,
John Wright
Although it is pretty easy to write a prequalified weld procedure for fillet welds.
You can also buy prequalified weld procedures from AWS. Checkout their publications catolog or go to the website and look for the process and materials you are working with.
