Welding procedure qualification based on ISO 15614-1 1

[MG79]

Dear All


I'm looking forward to hear from someone familiar with ISO 15614-1, Specification and qualification of welding procedures for metallic materials.

8.4.2 Welding positions

When impact and/or hardness requirements are specified impact tests shall be taken from the weld in the highest heat input position and hardness tests shall be taken from the weld in the lowest heat input position qualify for all positions.

In case of qualification for pipe butt welding, shall be conducting the two welding position in detail which 2G(lowest position), 5G(highest position). Am I correct ?

Many thanks
MG79

Those requirements should be addressed by the difference in the indicated test locations in Figure 6.
