... test coupon is made up of ASTM SA 790 with UNS S31803 equivalent to 2209 DSS grade, with dimensions of ϕ355.6 x t 12.70 mm 2 The chemical composition of the test coupon is shown in Table 1. 3 It was recommended to test the welder for the 6G position so that they may qualify for both pipe and plate welding in field joints during construction and turnaround. 1 The ASME Section IX design code for the standard 6G position before the start of welding test coupons is shown in Figure 1, and the appropriate groove joint position for the welder qualification test is shown in Figure 2. Note in Figure 2 that the leveller indicates horizontal and vertical positions, and the axis of the pipe is oriented at 45˚to 45˚to both the horizontal and vertical axis. The pipe orientation was ensured before the start of welding until its completion, as shown in Figure 3. ...
