Tungsten electrode performs well in welding titanium alloys and are the preferred electrode material for argon arc welding (TIG) and plasma welding titanium alloys, mainly in:
Strong Arc Stability
Tungsten electrodes have a high melting point and good electron emission properties, which can produce a stable and concentrated arc, which is conducive to controlling the heat input during titanium alloy welding and reducing welding defects.
Excellent High-temperature Performance
Titanium alloy welding has a high electrode tip temperature, and tungsten electrode is resistant to high temperature and ablation, which can keep the shape and size of the electrode stable for a long time and extend the service life.
Reduces Spatter And Weld Defects
High-quality tungsten electrodes can maintain good arc concentration, reduce weld spatter, reduce the risk of oxidation and nitriding, and ensure dense welds and excellent mechanical properties.
A Variety Of Tungsten Materials Are Available
Lanthanum tungsten electrode (WL15/WL20) is suitable for titanium alloy DC welding, with good arcing performance and less spatter;
Cerium tungsten electrode (WC20) performed well when welding thin titanium materials at low current;
Thorium tungsten electrode (WT20) arc concentration but radioactive restricted use.
Welding Quality Assurance
Tungsten electrode with inert gas protection can effectively prevent hydrogen embrittlement and oxidation of titanium alloys, and improve the corrosion resistance and mechanical properties of welded joints.
