Does anyone know what are the legal requirements/qualifications needed for welding steel/black iron gas pipework.
Cheers

  You should probably looking for a welder who can weld to API 1104 which is the American Petroleum Industry Standard.  These are guys that weld the high pressure transmission pipelines.

geezz they teach us at tech to weld black iron...i always knew that any welding needs to be done by a certified welder and could not fathom why they tried to teach us knowledge that we cant realisticly use in the real world...its dangerous to teach people enough so that they think they can do the job themselfs...the young fullas at tech now think they can go about willy nilly welding black iron pipe...dangerous....Even one of the tutors at tech(a real knoob) tried to tell us that it was eaiser and alot more cost effective to pipe out houses in black iron compared to say pexal...i asked him what about at every join the pipe needs to be chamfered for the initial penetration weld...he just put me down as best he could and then went on to say he just straight butt welded the pipe with no prep at all...what a winner he is leading those young guys down the garden path.
Tech teaching needs to be more uniform and structured and not have clowns like this trying to push there world view on young minds.
