The United Association of Plumbers and Pipefitters (UA) identifies their regular pipe welding checks with the letters UA, a sprint, and then a amount. Like UA-1, UA-2, etc.
There is a record available that goes all the way to UA-92. That does not imply there are only 92 tests ever provided. There are several much more alternatives but the Pipe fitters Union (UA) had to go all the way to # 92 to detect the most widespread pipe checks. Nevertheless, this does serve as variety of an instance to how quite a few opportunities exist for pipe welding certification exams.
With 4 distinct welding procedures made use of for pipe welding (Fuel Steel Arc / GMAW, Flux Core Arc / FCAW, Shielded Metallic Arc / SMAW, and Fuel Tungsten Arc / GTAW) and various distinct metal groups getting welded (like carbon metal, stainless steel, and even aluminum), its no wonder so lots of diverse pipe welding certification assessments are expected to certify welders for the scope of do the job getting accomplished on a career or career web-site.
ASME Portion IX is a generally referred to document in pipe welding utilized to decide welder certification needs as very well as qualification constraints.
Some of the widespread limits are thickness, position, and diameter of pipe.
For instance a welder passing a tig welding certification exam on 2 inch schedule 80 pipe in a 6G position is skilled to weld 1 inch and better diameter pipe, up to 436″ thick and in all positions.
But a welder passing a examination on 6″ plan 40 in a 6G placement is skilled to weld in all positions but only up to.560″ thick and only down to 2.875″ pipe diameter.
If you are reading through this and are wonder what rectal database they pulled these figures from, I am with you on that. Its appears form of foolish that once you have.560″ of filler steel deposited, that you are not experienced to place a lot more.
I am just expressing.
