- Scope
- This standard specities how a welding procedure specification is approved by welding procedure tests for on land and offshore site butt welding of tsansmission pipelines under normal ahnospheric conditions. Tests are carried out in accordance with this standard unless additional tests (e.g. CTOD tests and all weld metal tensile tests) are specitied by the relevant application standard or contract when these apply This standard defines the conditions for the execution of welding procedure approval tests and the limits of validity of an approved welding procedure for all practical welding operations w i t h the range of variables Wed in clause 8. It applies to the arc welding of steels of groups 1,2 and 3 according to CR 12187. The principles of this standard can be applied to other fusion welding processes subject to agreement between the contsacting parties. The requirements for welding procedure specification and qualification for hyperbaric and "wet" welding are not covered by this supplementary standard.
