> 6G Welding Position

Can the 6G / H-L045 weld test only be carried out on pipes or is it possible to qualify it on plate to still cover you for both? Read on certain forums that they carried out a plate in 45 welding from underneath and reckoned it covered them for pipe? don't know how true this is, i find some of these standards are very ambiguous.

I think they mean that they used this plate test for the prolongation of existing 6G / H-L045 certs which is perfectly above board.

Pipe will cover pipe and plate in any position however plate tests will only cover u for plate buddy

For original qualification both ASME IX (6G) and ISO 9606 (H-L045) require pipe to be qualified with pipe.

ASME IX prolongation of qualification allows pipe or plate to be used.
ISO 9606 revalidation of qualification is a bit more ambiguous.
Clause 9.3
a) Pipe must be used
b) Pipe must be used ( The weld tested shall reproduce the original test
conditions except for thickness and outside diameter.)
c) It appears pipe or plate may be used

Hope that helps,
