Jeff,
have seen this hopefully not too late.
I have occupied myself recently with a topic that required excessive standard- and code's interpretation work. Unfortunately it's extremely intricate to answer your queries with some two or three words.
Hence, please let me recommend to you to have a closer look at:
- EN 15614:2004 + A1:2008, Specification and qualification of welding procedures for metallic materials - Welding procedure test - Part 1: Arc and gas welding of steels and arc welding of nickel and nickel alloys
- EN ISO 15607:2003, Specification and qualification of welding procedures for metallic materials - General rules
- EN ISO 15609-1:2004, Specification and qualification of welding procedures for metallic materials -Welding procedure specification - Part 1: Arc welding
- EN ISO 15613:2004, Specification and qualification of welding procedures for metallic materials - Qualification based on pre-production welding test
- EN 288-2:1992 + A1:1997, Specification and approval of welding procedures for metallic materials - Part 2: Welding procedure specification for arc welding
- EN 288-6, Specification and approval of welding procedures for metallic materials - Part 6: Approval related to previous experience
- EN 288-7, Specification and approval of welding procedures for metallic materials - Part 7: Approval by standard welding procedure for arc welding
Also I would like to kindly and strongly recommend to occupy yourself with the EN ISO 3834 ff. series. This is
the EN ISO key code series with particular respect to all quality management issues relating to welding as being defined as a special process.
If you are going to deal increasingly with EN ISO welding codes, from my humble point of view this is a must-have to be integrated to your library.
Hope this helps a bit.
Stephan
