Ti Alloy TIG Fabrication: Difficulties and Approaches
Welding Ti alloys with the TIG process presents unique challenges beyond those encountered with carbon steel. The alloy's elevated reactivity, producing scale formation that can cause inclusions and reduced ductility, is a critical concern. Furthermore, Ti's minimal thermal conductivity makes pipe bending regulating the heat-affected zone challenging. Remedies involve meticulous degreasing to remove scale before and during joining, employing protective atmospheres like argon or He to prevent scale formation, and utilizing precise welding parameters – including lower amperage and correct welding rates. Adequate technique and experience are vital for successful titanium fabrication.
