WL15 tungsten electrode
WLa electrode
LA and W. electrode: add lanthana in the mental W.
The advantages of La and W electrode:The better mechanical cutting
The better anti- creep
The better anti- creep Higher temperature in second crystallization Better extensibility
LA and W. electrode has been welcomed in the world, especially the kind of electrode containing 1.5%La and W. According to scientific research , this one is the nearest to Th and W electrode in the conductivity,so the welding technicians can change the electrode easily ,without changing the equipment parameter.
