The most common lanthanum Welding Electrodecontaining three percent of lanthanum oxide (La203), known as lanthanum oxide. In Europe and Japan, Lanthanum tungsten electrode in most applications has been the most commonly used alternative Cast Iron Electrodes 2% of the containing lanthanum oxide, lanthanum oxide 1.5% and three kinds of lanthanum oxide 1%. Three lanthanum oxide has the lowest electron work function, the arc is the easiest, lowest tip temperature, which helps prevent grain growth and enhance the service life. Lanthanum tungsten electrode containing La 2% of test that: If the overload current longer life than the thorium tungsten arc easier for most use. Especially good at

(A) to prevent thermal shock,

(B) short cycle welding repeat the ignition, welding

(C) to avoid contamination. Welded pipes, welders of this lanthanum tungsten electrode is particularly satisfactory.

Long service life, reduced downtime. Moreover, in normal circumstances, 1.5% lanthanum oxide, lanthanum tungsten electrode, low current, easy arc starting and stable low-current arc. Lanthanum in the tungsten electrode is a rare earth, and no radioactivity. Sale and use in the United States, Europe and Japan, but has been providing Beijing Solton Tungsten & Molybdenum Technology Co., Ltd. from 1993 to this lanthanum tungsten electrode. Lanthanum tungsten electrode is mainly used for DC welding, welding in the exchange will have good results. Lanthanum tungsten electrode containing 1.0% lanthanum oxide and cerium tungsten electrodes in the market.
