Tungsten Lanthanum Thorium TIG GTAW Welging Rod

Product Detail

Tungsten electrode/ TIG welding rod

 

Tungsten electrodes are widely used for welding with the property of non-radiative, low melting rate, high melting point, corrosion resistance, high density, good thermal conductivity and good electrical conductivity.
