Titanium Gas Tungsten Arc Joining: Problems and Remedies
Welding Ti alloys with the TIG process presents distinct challenges beyond those encountered with steel. The metal's high reactivity, leading to film formation that can cause voids and brittle formability, is a major concern. Furthermore, the alloy's low thermal conductivity makes regulating the HAZ problematic. Remedies include meticulous degreasing to remove oxides before and during fabrication, employing inert gases like Ar or He to minimize scale formation, and utilizing careful conditions – including decreased voltage and appropriate welding rates. Correct procedure and experience are essential for successful titanium joining.
304 Stainless Tig Welding: Achieving Strength
To obtain superior joint strength when executing Tig welding on 304 stainless, several critical practices must be adhered to . To begin with , adequate joint surface condition is vital ; completely eliminating all impurities via abrasive methods like sanding is necessary . Following this, use the appropriate filler metal , typically a matching grade to the base component. Furthermore , preserve a uncontaminated welding environment, shielding the weld area from atmospheric pollutants with ample argon gas blanket.
