Ti TIG Fabrication: Problems and Solutions
Welding Ti alloys with the TIG process presents specific challenges beyond those encountered with ferrous metals. The alloy's high reactivity, leading to film formation that can cause voids and brittle toughness, is a principal concern. Furthermore, the alloy's reduced thermal response makes regulating the heat-affected zone challenging. Solutions involve meticulous preparation to remove oxides before and during joining, employing inert gases like pure argon or helium to minimize scale formation, and utilizing precise welding parameters – including reduced amperage and appropriate travel speeds. Adequate technique and experience are crucial for successful Ti alloy joining.
