Lets say I want my guys to be covered in thicknesses of 18 gage to 3/4". The Joint types are T, Lap, Edge, Butt. The welds are Fillets, Flare V, Flare Bevel, Square groove and Single V. What is the minimum tests I need to perform on the guys to be sure all bases are covered? Also D1.3 2008 in Table 4.4 under THICKNESSES says: Thickness tested and thicker. What is THICKER? When something like that is stated in this code does it mean the thicknesses that this particular code covers?
Here is what I come up with:
For square groove welds figure 4.1 of AWS D1.3 needs to be performed on 18 gage sheet steel. This will qualify you up to 3/16".
For fillet welds figure 4.2C of AWS D1.3 needs to be performed on 18 gage sheet steel. This will qualify you up to 3/16".
For flare V and Flare bevel welds figure 4.3C of AWS D1.3 needs to be performed on 18 gage sheet steel. This will qualify you up to 3/16".
For single V welds figure 4.31 of AWS D1.1 needs to be performed on 3/8" plate. This will qualify you from 1/8" to 3/4" in both fillets and groove welds.
Any thoughts??

I think you've about got it, provided you stay within d1.3 for gauge thickness to 3/16".
For square groove also look at 4.7.2 (3) (b)(ii) (d1.3
Single V, you are correct on thickness, or qualified to thickness tested x2
HAHA Here in MN we have good work ethic. :) And thank you for the input. Greatly appreciated.
Be aware of coating limitations in D1.3.
