No welding. I have a cheap welder I've used for other projects, but apparently to weld titanium a shielding gas welder is required, which I don't have. I opted not to risk using my low end welder.

I'm sure it will fit the Alice hip pad and shoulder straps. I'll have to wait and see about the pack though. It will be borderline if I can make it fit.

This is my first experience at working with titanium and bending tubing of any kind so it was a learning experience.
