Pipe Welding Certification Test – UA Welding Test

2019-04-09 Technology No comment

The Joint Plumbers and Plumbers Association [UA] identifies their standard pipe welding tests with the letters UA, dashes and numbers. Like UA-1, UA-2, etc.

There is a list available until UA-92. This does not mean that there are only 92 tests. There are more possibilities, but the Pipe Fitter Union [UA] must go all the way to #92 to determine the most common pipe tests. However, this does serve as an example of how many possibilities exist for pipe welding certification testing.

4 different welding processes for pipe welding [gas metal arc / GMAW, flux core arc / FCAW, shielded metal arc / SMAW and gas tungsten arc / GTAW] and several different metal group welding [eg carbon steel, stainless steel] There is no doubt that in order to complete the scope of work at work or at the job site, the welder needs to perform many different pipe welding certification tests.

Part IX of ASME is a commonly used document in pipe welding to determine welder certification requirements and qualification limits.

Some common limitations are the thickness, location and diameter of the pipe.

For example, the welder passes the tig weld certification test on a 2-inch 80-gauge pipe at 6 inches and is qualified to weld 1 inch and larger diameter pipes up to a maximum thickness of 436 inches and in all positions.

However, the welder passed the 6" timetable 40 test at the 6-inch position and was qualified to weld at all locations, but only 560 inches thick and the pipe diameter was only 2.875".

If you are reading this article and want to know which rectal database they are extracting from, I will be with you. It seems a bit silly, once you have 550 inches of filler metal deposit, you are not qualified to put more.

I just said.
