Pipe Welding Certification Checks – UA Welding Tests

The United Association of Plumbers and Pipefitters (UA) identifies their typical pipe welding assessments with the letters UA, a sprint, and then a number. Like UA-1, UA-2, and so forth.

There is a listing accessible that goes all the way to UA-92. That does not imply there are only 92 tests ever given. There are lots of much more options but the Pipe fitters Union (UA) had to go all the way to # 92 to identify the most widespread pipe exams. Even so, this does provide as form of an example to how quite a few choices exist for pipe welding certification exams.

With 4 diverse welding processes applied for pipe welding (Fuel Metal Arc / GMAW, Flux Main Arc / FCAW, Shielded Steel Arc / SMAW, and Fuel Tungsten Arc / GTAW) and numerous different metallic groups currently being welded (like carbon metal, stainless metal, and even aluminum), its no marvel so quite a few various pipe welding certification tests are expected to certify welders for the scope of perform becoming carried out on a work or job web site.

ASME Section IX is a frequently referred to doc in pipe welding used to determine welder certification necessities as well as qualification limits.

Some of the common limits are thickness, position, and diameter of pipe.

For instance a welder passing a tig welding certification check on 2 inch schedule 80 pipe in a 6G place is experienced to weld 1 inch and higher diameter pipe, up to 436″ thick and in all positions.

But a welder passing a examination on 6″ plan 40 in a 6G position is qualified to weld in all positions but only up to.560″ thick and only down to 2.875″ pipe diameter.

If you are examining this and are surprise what rectal databases they pulled these quantities from, I am with you on that. Its looks form of foolish that as soon as you have.560″ of filler steel deposited, that you are not skilled to put a lot more.

I am just declaring.
