Why are titanium exhaust parts TIG-welded rather than MIG-welded?

2026-10-15

Titanium has to be welded in a protected atmosphere. Once titanium is heated in air it absorbs oxygen and nitrogen, and the joint embrittles — a weld that looks acceptable can fail at the seam later. TIG welding suits this because the operator controls the arc and the heat input precisely on thin-wall tube, and the molten pool can be shielded while it cools.

MIG deposits metal faster, but speed is the wrong trade on titanium tube: thin walls give you a narrow window between a full-penetration weld and a burnt-through one. Fupower's exhaust facility TIG-welds titanium parts in-house, including the heavier fabrication work on flanges, hangers and O2 bungs, so the joint and the finish are controlled on the same floor as the bending.
