Heres a ~1” cube of 18 gauge stainless I did to practice heat input, definitely a little tricky but overall it was pretty fun! #8 cup, 25 cfh, 1/16” er316L, can’t remember the amps

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.

First of all, I want to give a huge shoutout to @Grant Pratt for sending this out to me. Without him I wouldn’t have been able to experience this amazing material! Here was my set up, #16 cup, 3/32 thoriated tungsten(wouldn’t recommend, use lanthanated) 35 CFH. I think the filler was .45 I don’t know the exact type Grant sent them with the piping 🙏. Purged the inside with 3D printed plugs (10 cfh). Titanium is strange but easy and pleasant to weld with ( in my opinion), I honestly prefer it over SS. The arc and puddle were supper stable but very liquid. I noticed I needed to weld much slower then I would with SS to get proper penetration. Here are a couple of pictures of my welds. Once again I can’t thank Grant enough for this Thank you!
