Titanium frames are welded with laser welding or argon arc (TIG) welding, and the choice depends on the joint design and order volume. Titanium reacts with oxygen at welding temperature, so the joint must be shielded by argon gas while the metal is fused. Done correctly, the weld is as strong as the base wire and nearly invisible after polishing; done poorly, it becomes brittle, discolored, and prone to cracking, which is why titanium frames cost more to make than nickel silver or monel ones.

How the Welding Process Works

1. Joint preparation: the wire ends are cleaned and fitted so the gap is tight; contamination or gaps cause weak welds.
2. Argon shielding: gas flows over the joint to block oxygen, because hot titanium absorbs nitrogen and oxygen and embrittles instantly.
3. Fusing: a laser beam or TIG arc melts the wire ends together; laser welding offers pinpoint control for bridges and pad arms, while TIG suits thicker joints.
4. Cooling and inspection: the joint cools under continued shielding, then welds are checked for porosity, cracks, and alignment.
5. Finishing: the weld bead is ground and polished until the joint disappears into the frame line.

Why Titanium Welding Affects Price

Titanium welds demand dedicated equipment, gas shielding, and welders trained specifically on the material, and rejected joints cannot simply be reworked like steel. This process barrier is a key reason beta titanium and pure titanium lines sit above nickel silver on quotations.
