The United Affiliation of Plumbers and Pipefitters (UA) identifies their widespread pipe welding exams with the letters UA, a dash, after which a amount. Like UA-1, UA-2, etcetera.

There’s a itemizing on the market that goes all the best way to UA-92. That doesn’t suggest there are solely 92 checks ever specified. There are plenty of far more choices however the Pipe fitters Union (UA) needed to go all the best way to # 92 to find the commonest pipe checks. Nonetheless, this does present as sort of an instance to what number of choices exist for pipe welding certification checks.

With 4 totally different welding processes made use of for pipe welding (Gasoline Metal Arc / GMAW, Flux Primary Arc / FCAW, Shielded Metal Arc / SMAW, and Gasoline Tungsten Arc / GTAW) and a number of other varied metallic teams getting welded (like carbon steel, stainless steel, and even aluminum), its no shock so plenty of varied pipe welding certification exams are important to certify welders for the scope of function getting carried out on a job or activity internet web page.

ASME Phase IX is a sometimes referred to doc in pipe welding employed to determine welder certification wants as very properly as qualification restrictions.

Among the widespread constraints are thickness, place, and diameter of pipe.

For instance a welder passing a tig welding certification check on 2 inch plan 80 pipe in a 6G place is licensed to weld 1 inch and better diameter pipe, as much as 436″ thick and in all positions.

However a welder passing a examine on 6″ agenda 40 in a 6G scenario is skilled to weld in all positions however solely as much as.560″ thick and solely all the way down to 2.875″ pipe diameter.

If you’re this and are query what rectal databases they pulled these numbers from, I’m with you on that. Its would appear sort of foolish that on the time you’ve.560″ of filler metallic deposited, that you’re not licensed to place far more.

I’m simply indicating.
