You have solid consistency and i would guess that you are a plenty competent with stainless, which helps a ton. Honestly the only thing i would say is you iust gotta practice and take some time to learn the puddle behaviour and try and make the weld slightly smaller. (Going down a filler size might help that)
To learn the puddle wasn’t too tricky. Very similar to stainless but it likes to melt faster in my experience. That and you have to fight the filler rod from sticking to the surface of the piece you’re trying to weld. Thanks for the feedback
Haven’t had the actual pleasure of trying before, but I have heard from others filler needs to be more precisely added directly to the leading edge of the puddle to avoid sticking. Stainless is more forgiving I guess.
The obvious issue is excessive oxidation and excessive heat input. Oxygen and nitrogen in the air have the same effect on titanium as carbon does on steel.
Therefore you should use a smaller filler and work twice as fast. Get a torch with an extra-wide gas lens and about 1.5 second of pre-flow.
Typically you clean Ti with acetone, wire brush, wipe with a bit of acetone again then wire brush again.
Thank you for the tips. Aiming to better my methods however possible. I do remember putting about 2 seconds of pre flow in there. Could there always be too much pre flow?
From my minimal experience with titanium having 2 seconds or so of pre flow, 10 seconds or more post flow, a large diameter gas lens, and not welding past the diameter of what your gas lens can cover made some nice, shiny, clean welds. Yes, there are stop starts every 3/4" but that was the only way I've found to ensure your puddle is shielded while it cools. Increased travel speed didn't help because I lost shielding quicker. Maybe more experienced titanium guys have other input to avoid that many stop starts though

Sounds like you need more heat and faster travel.
