Good luck. No gunsmith or shop is going to be set up for it as it's a somewhat complicated process. It's a LOT more difficult than a simple weld on steel with a steel pin. Maybe a small welding shop since it's not gunsmithing in the legal definition unless it's one of the guns that has the upper as the serialized "firearm." A couple articles on welding titanium show just how much is involved, https://www.millerwelds.com/resources/a ... -tube-pipehttps://weldguru.com/titanium-welding/# ... 20Titanium?

I'm confused that tig process is damn near the same as for tig anything else other than argon which most welders are gonna have anyways for stainless. Finding a suitable pin would the the hardest part. Or are there people out there doing a pin and weld with mig or smaw?

You can tig titanium outside an argon chamber, and even without back purging. You will definitely get some oxygen uptake, but this isn’t a fatigue critical application where embrittlement is a prime concern. Not sure what pin diameter is needed, but the first place to look for pin material is the titanium filler rod itself.

No filler rod on a pin and weld how I do them, I use a 3/32 drill bit and cut the back side of the bit off, grind it to be about 1/32 high in the hole and then when I make a puddle it flattens out and into the muzzle device.

I can see how that would work with this geometry and application. But I would add that steel cannot be welded to titanium for any structural application. The fusion zone would be full of very brittle Ti-Fe intermetallics.

JB weld the pin in

I think Ray was eluding to using the tit filler ROD for pin material. Dont exclude silver soldering it as an option. Might be something to talk to a custom jewler about if your not up to the task yourself.

Could one use a steel pin and weld over it with titanium filler? Not welding the pin to the muzzle device, just have it completely covered over in ti?

Don’t see how. Titanium melts at over 3000 F. Steel at 2750F. Getting things hot enough to melt titanium would also melt the steel pin.
