Hi Bro!!!
ISO 15614-1 para 8.4.3 type of joint / weld (For Level 2) mentioned:
a) butt welds qualify full and partial penetration butt welds and fillet welds, while fillet weld tests are required where T-joints are performed by fillet welds or partial penetration butt welds in the predominant form of welded connections in relation to the design and production welding
b) full penetration butt welds qualify full and partial penetration butt welds and fillet welds in any type of joints
=> "a" tell me, when PQR with butt joint and Full penetration butt weld, Fillet weld test is required if I want to welding fillet weld in production.
But "b" tell me above PQR can approved for Full/Partial and fillet weld in any type of joints
Hence, what are differences between "a" and "b"?
Which case I can use "a" and which case I can use "b" to write WPS.
Hope receipt you advice in that case.
Thanks Bro !!!
