I’ve listed the tests for an upcoming job. Just wanted to check how these tests differ out at the shipyards from other places. I haven’t worked in shipyards before so just wanted to see if anyone would share their experience with any of these tests thanks!
TESTS 1-6: The first 6 tests will be 1/2’’ pipe (.083 wall thickness) to socket joints. Materials tested will be stainless steel, copper nickel, and carbon steel.
3 of the joints will be in the 4F restricted position (joint is 6 inches above deck and 12 inches from bulk head).
The other 3 will be in the 5F restricted position (joint 6 inches off of bulkhead and 12 inches away from overhead).
TESTS 7-10: Then you will be tested on 4” heavy wall J-Bevel pipes with an E.B ring in each joint. The 3 tests will be stainless steel, cabin steel, and copper nickel.
4” heavy wall carbon steel pipe with a V-Bevel and a 1/4’’ backing ring. All 4 of these tests will be in the 6G restricted positions.
TESTS 11: Pulse-TIG proficiency test on thin-wall 2’’ and thin-wall 4’’ stainless steel piping which will require you to use a mirror.
TESTS 12-13:stainless steel 1/2’’ pipe (.083 wall thickness) to socket joints using the Pulse-TIG process, in the 4F restricted and 5F restricted positions.
root penetration into joint.
There are no open root tests conducted as well.

Pretty much standard stuff for the day in the life of a shipyard pipefitter. The copper-nickel is probably sil-braze with socket weld fittings and the mirror welding takes a while to get used to. In the tight locations concentrate on making good solid welds and don't worry about making them look fancy.
