2009年10月22日 · Good morning all, As I am currently working with AWS D1.1 & D1.5 clarification of D1.5 Clause 5.21.3 would be greatly appreciated. As far as I can see ASTM A 36 and ASTM A 709 Grade 36 are both Group 1 materials (D1.1 Table 3.1) and have the same minimum yield strength and same tensile range. AWS D1.5 Clause 5.21.1 states " Purpose.

2009年1月28日 · A summary of differences between D1.5:2008 and D1.1:2008 (feel free to add to this list). In short D1.1 and D1.5 are different enough that when you switch between the codes you need to leave any preconceived notions behind otherwise you will likely get burned.

2010年4月28日 · The applicable code, be it AWS D1.1 or D1.5, will typically provide different acceptance criteria for static tensile, static compressive, and cyclic load conditions. The Level III would tell the Level II and Level I technicians which criteria to apply.

2007年3月27日 · According to AWS D1.5 Sect. 12.16.1.2, qualified NDT personnel must be "supervsed" by a ASNT level III. The commentary states what "under supervision" means. I am currently providing a QA inspection of a fracture criticle bridge members. The shop insists that the code commentary is not enforceable, and they will interperate what supervision ...

2010年7月5日 · D1.5 does not address tubular structures, so there is no equivalent welder qualification test. Typically a welder qualified to D1.5 is acceptable for work meeting D1.1, but a welder qualified to D1.1 is not permitted to weld per D1.5 without requalification per D1.5 I hope this is some help in answering your question. Best regards - Al

2005年9月6日 · According Figure 5.2 (AWS D1.1) "weld access hole geometry" point 4. the weld shall not be not returned through opening but the AWS D1.5 does not mention anything about it. According point 2.8.1.7 (AWS D1.5) fillet welds which support a tensile force that is not parallel to the axis of the weld shall not terminate at the corners of parts or ...
