"When you're working with titanium, it is far more challenging than aluminum," Zablocky says. "The bending, grinding, and welding of that thinner tube and that wall thickness is a delicate process that requires some skill. That's not the case with aluminum – it's very easy to weld." The basic problem is atmospheric contamination so that the weld zone can become very crack sensitive. Oxygen and nitrogen are picked up from the air and entrained in the gas shield; impure shielding gas and hydrogen derived from moisture or surface can be a real problem. Titanium jewelry is very (very) tough. It can be worn in all kinds of environments and conditions. The metal will scuff and show wear over time but holds up without breaking a sweat, cracking, breaking, bending, etc. Titanium and its alloys are often welded with the gas tungsten-arc (GTA or TIG) and gas metal-arc (GMA or MIG) welding processes. Resistance, plasma arc, electron beam, and friction welding are also used on Titanium to a limited extent. All of these processes offer advantages for specific situations.
Titanium and stainless steel cannot be welded reliably because these materials are characterized by mutual metallurgical incompatibility. This is due to the formation of brittle intermetallic compounds that arise when Titanium is welded with stainless steel (Pardal et al., 2016). Titanium does not burn normally and has an extremely high melting point of 1668°C (3032°F). Even under extreme heat, Titanium will not combust or emit any toxic fumes into the air. Titanium does not suffer from any cracking issues other than possible cold cracking of the HAZ from embrittlement. Titanium and Titanium alloys can be arc welded with the gas-shielded processes, TIG, MIG, or Plasma TIG.
