Product Description

WL20 lanthanum tungsten electrode for welding

1. Application: inert gas arc welding, plasma welding, cutting, spraying, melting electrode, ect.

2. Features:

(1) High melting point, arc stability, no self - consumption.

(2) Add 0.03 ~ 4% Th02, Zr02, La02 and Ce02 in tungsten to reduce the burning loss of tungsten electrode, increase its service life and avoid polluting welding seam.

(3) increase the electron emission ability of tungsten electrode, make it arc starting current, stable arc current is small, arc starting gap and arc breaking gap are big, so the quality of welding seam is high.
