TIG uses a tungsten electrode and a separately fed filler rod, so heat input can be controlled very precisely. On thin-wall tube that control is what prevents burn-through and internal spatter.
Material cost is only part of the answer. Titanium demands tighter heat control, full inert-gas shielding and more careful handling at every step - and mistakes cannot be dressed out.
We work primarily in 304 stainless for exhaust components. Here is what the grade actually controls, and when a higher-chloride-resistance option is worth asking about.
