Ti TIG Joining: Challenges and Remedies
Welding Ti with the gas tungsten arc process presents unique problems beyond those encountered with ferrous metals. The metal's significant reactivity, leading to oxide formation that can cause porosity and reduced formability, is a principal concern. Furthermore, Ti's reduced thermal response makes controlling the heat-affected zone difficult. Remedies involve meticulous degreasing to remove oxides before and during welding, employing protective atmospheres like argon or precision metal products He to prevent oxidation, and utilizing precise welding parameters – including reduced power and suitable travel speeds. Correct method and skill are vital for reliable Ti joining.
