Pipe Welding Certification Checks – UA Welding Checks

HQ Gadget

The United Association of Plumbers and Pipefitters (UA) identifies their standard pipe welding exams with the letters UA, a dash, and then a amount. Like UA-1, UA-2, etc.

There is a list available that goes all the way to UA-92. That does not necessarily mean there are only 92 tests ever given. There are quite a few extra possibilities but the Pipe fitters Union (UA) had to go all the way to # 92 to detect the most frequent pipe exams. However, this does provide as form of an case in point to how many options exist for pipe welding certification exams.

With 4 distinct welding processes employed for pipe welding (Gas Metal Arc / GMAW, Flux Core Arc / FCAW, Shielded Metal Arc / SMAW, and Gasoline Tungsten Arc / GTAW) and many various steel groups getting welded (like carbon metal, stainless steel, and even aluminum), its no speculate so numerous distinctive pipe welding certification tests are needed to certify welders for the scope of work getting accomplished on a career or work internet site.

ASME Part IX is a usually referred to document in pipe welding utilized to decide welder certification necessities as well as qualification limits.

Some of the widespread restrictions are thickness, situation, and diameter of pipe.

For case in point a welder passing a tig welding certification check on 2 inch program 80 pipe in a 6G posture is experienced to weld 1 inch and increased diameter pipe, up to 436″ thick and in all positions.

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

If you are looking through this and are marvel what rectal databases they pulled these numbers from, I am with you on that. Its appears kind of foolish that when you have.560″ of filler steel deposited, that you are not qualified to place a lot more.

I am just expressing.
