Ti TIG Welding: Problems and Approaches
Welding titanium with the gas tungsten arc process presents specific challenges beyond those encountered with ferrous metals. The metal's significant reactivity, leading to film formation that can cause porosity and reduced formability, is a major concern. Furthermore, Ti's reduced thermal conductivity makes regulating the HAZ challenging. Approaches involve meticulous cleaning to remove contaminants before and during joining, employing inert gases like Ar or a helium mix to prevent scale formation, and utilizing careful settings – including decreased amperage and appropriate travel speeds. Proper method and experience are vital for successful Ti fabrication.
304 Stainless Tig Welding: Maximizing Strength
