I have qualified a WPS in accordance with D1.3 (2008 edition) Table 4.1, Figure 4.2c using 10 gage material. I understand that per Table 4.2 10e this allows me a minimum thickness of 16 gage. When it comes to qualifying welders to this WPS does section 4.7.2(2) direct me to perform seperate fillet weld, flare-bevel groove and flare-V groove welds in each position qualified, horizontal and vertical? This would indicate about six different welders quals. Also is the material thickness to be used 16 gage? Or is Table 4.4 the guidance which seems to contradict 4.7.2.(2)? Thanks for any help.
