The United Affiliation of Plumbers and Pipefitters (UA) identifies their typical pipe welding checks with the letters UA, a sprint, and then a number. Like UA-1, UA-2, and many others.
There is a listing available that goes all the way to UA-92. That does not mean there are only 92 exams at any time supplied. There are quite a few far more opportunities but the Pipe fitters Union (UA) experienced to go all the way to # 92 to identify the most popular pipe assessments. Nevertheless, this does provide as variety of an case in point to how quite a few options exist for pipe welding certification checks.
With 4 distinctive welding processes employed for pipe welding (Fuel Metallic Arc / GMAW, Flux Core Arc / FCAW, Shielded Metallic Arc / SMAW, and Gas Tungsten Arc / GTAW) and several distinct steel teams currently being welded (like carbon steel, stainless steel, and even aluminum), its no surprise so several distinctive pipe welding certification exams are demanded to certify welders for the scope of work being done on a task or occupation website.
ASME Area IX is a frequently referred to doc in pipe welding made use of to figure out welder certification prerequisites as properly as qualification limitations.
Some of the prevalent constraints are thickness, position, and diameter of pipe.
For case in point a welder passing a tig welding certification exam on 2 inch agenda 80 pipe in a 6G position is certified to weld 1 inch and bigger diameter pipe, up to 436″ thick and in all positions.
But a welder passing a take a look at on 6″ schedule 40 in a 6G situation 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 database they pulled these numbers from, I am with you on that. Its appears type of silly that the moment you have.560″ of filler metal deposited, that you are not competent to set far more.
I am just expressing.
