Ti Alloy TIG Welding: Difficulties and Remedies
Welding Ti alloys with the gas tungsten arc process presents distinct difficulties beyond those encountered with steel. The material's elevated reactivity, resulting oxide formation that can cause inclusions and poor metal stamping ductility, is a major concern. Furthermore, the alloy's reduced thermal heat transfer makes regulating the heat-affected zone difficult. Approaches involve meticulous cleaning to remove contaminants before and during fabrication, employing shielding gases like pure argon or helium to prevent oxidation, and utilizing precise welding parameters – including reduced power and suitable welding rates. Proper procedure and experience are essential for successful Ti welding.
Stainless Steel Tig Welding: Maximizing Strength
