Welding grade 2 titanium

[welderdude]

I made myself a couple of titanium anodes today by welding a piece of 1/4" round titanium rod to a titanium mesh thats coated in a titanium oxide, iridium oxide, and ruthenium oxide. This one was the first time I have ever welded anything titanium. I used some sandpaper to scrape off the coating in the area i welded. It wasn't too bad although I had no filler to use. its just a fusion tack to hold the pieces together. Its for an electrolysis cell. the cathodes are just 316 ss sheet metal that I drilled a bunch of holes in.

I used my powertig 225 with a sharp 3/32 tungsten and a #7 gas lens. i think i was around 120 or so amps.

If anyones wondering about what I'm doing, it evolves the electrodes, salt water, and the power supply thats pictured.
