Pipe Welding
Heres a few shots of some Super Duplex SCH160 1.5"DIA pipe ive been working on. The fabrication is a cooling coil for the Oil and Gas sector, I cant post the actual job but this is an extra joint that had to be cut out and i thought it was perfect to post here.
Root - 70A
Hot pass - 100A
Fill - 105A
Cap - 115A
The WPS specifies an interpass temp of 60°C that must be adhered to.
All welds on the job are 100% X-RAY, including DPI and a ferrite check before pickling and passivation.
