The U . s . Association of Plumbers and Pipefitters (UA) identifies their standard pipe welding tests using the letters UA, a touch, along with number. Like UA-1, UA-2, etc.
There’s a listing available which goes completely to UA-92. That doesn’t mean there are just 92 tests ever given. There are lots of more options however the Pipe fitters Union (UA) needed to go completely to # 92 to recognize the most typical pipe tests. However, this may function as type of a good example to the number of options exists for pipe welding certification tests.
With 4 different welding processes employed for pipe welding (Gas Metal Arc / GMAW, Flux Core Arc / FCAW, Shielded Metal Arc / SMAW, and Gas Tungsten Arc / GTAW) and many different metal groups being welded (like carbon steel, stainless, as well as aluminum), its no question a wide variety of pipe welding certification exams are needed to approve welders for that scope of labor being carried out on the job or job site.
ASME Section IX is really a generally known document in pipe welding accustomed to determine welder certification needs in addition to qualification limitations.
A few of the common limitations are thickness, position, and diameter of pipe.
For instance a welder passing a tig welding certification test on 2 inch schedule 80 pipe inside a 6G position is capable of weld 1 ” and greater diameter pipe, as much as 436″ thick as well as in all positions.
However a welder passing an evaluation on 6″ schedule 40 inside a 6G position is capable of weld in most positions only as much as.560″ thick and just lower to two.875″ pipe diameter.
If you’re studying this and therefore are question what rectal database they pulled these figures from, I’m along with you with that. Its appears type of silly that after you have.560″ of filler metal deposited, that you’re not capable of put more.
