Characteristics of lanthanum tungsten electrode

He is particularly good at (a) preventing thermal shock, (b) welding well under the condition of repeated ignition in short-period welding, and (c) avoiding pollution. When welding pipelines, welders are particularly satisfied with this lanthanum-tungsten covered electrode. Due to the long service life, the downtime is reduced. Moreover, lanthanum tungsten electrode with 1.5% lanthanum oxide is generally needed, which is easy to arc under small current and can stabilize the arc under small current. Lanthanum in tungsten electrode is a rare earth and has no radioactivity. This kind of lanthanum tungsten electrode is mainly used for DC welding, and it will also have a good effect in AC welding. Lanthanum tungsten electrode and cerium tungsten electrode containing 1.0% lanthanum oxide have appeared in the market at the same time.
