I only have D1.6-1999 right now, hoping someone can update me on the following:
Have any of the following requirements changed since the 1999 edition:
1. Paragraph 4.1.7 indicates one CJP groove weld IN ANY POSITION qualifies ALL positions....IS THIS STILL
TRUE? IF YES.....WHY? (This would be DRASTICALLY different than AWS D1.1, ASME, ETC.)
2. CJP groove weld qualifies ALL PJP AND FILLETS.....IS THIS STILL TRUE?
3. Paragraph 4.5.1 require Reduced Section Tension tests, Transverse Guided Bend tests, Longitudinal Root &
Face Guided Bend tests (optional, see 4.6.5).......SHOULD THIS READ AS "(optional, see 4.6.4)"?
4. Figure 4.4 requires test plates to be 10-inch wide x 12-inch long......IS THIS SIZE STILL TRUE?
5. AWS D1.1 requires test plates to be 14-inch wide x 20-inch long.......does anybody know why the huge difference in size as compared to D1.1??)
6. Are the qualification Groove welds shown in Figure 4.3 or Figure 4.4 typically open butt or with a backer?
Thankyou for any help on this.
