Ti TIG Welding: Difficulties and Solutions
Welding Ti with the gas tungsten arc process presents specific problems beyond those encountered with ferrous metals. The metal's significant reactivity, leading to oxide formation that can cause inclusions and brittle toughness, is a major concern. Furthermore, Ti's low thermal response makes controlling the heat-affected zone problematic. Remedies require meticulous cleaning to remove scale before and during welding, employing protective atmospheres like pure argon or a helium mix to inhibit reaction, and utilizing careful conditions – including reduced power stainless steel welding and appropriate feed rates. Correct technique and skill are crucial for reliable titanium fabrication.
Stainless Steel Tig Welding: Maximizing Strength
To obtain superior joint strength when executing Tig welding on austenitic steel , several critical practices must be followed .
