Product Description Wl20 Tungsten Electrode 2% Thoriated Tungsten Electrodes (WT20) for Welding MaterialPacking: Plastic boxesModel No.: WT20Productivity: 500, 000, 000 PCS/yearUnit Price/Payment: T/TOrigin: Henan, ChinaMin. Order: 1000 PCSAssistant Appliance: Arc-Protection HelmetType: CO2 Gas Protection WeldingExport Markets: North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, MID East, Eastern Asia, Western EuropeProduct Description:The most common electrode used today. 2% Thoriated Tungsten Electrodes or WT20 contain a nominal 2 wt-% of thorium oxide (ThO2) which is evenly dispersed throughout the entire length of each rod. Offers excellent resistance from weld pool contamination, a stable ARC and easy starting capabilities. Generally used on DC electrodes negative or straight polarity.Principally used on: Carbon steels, Stainless Steels, Nickel, Nickel Alloys, Titanium, Copper AlloysTip Electrode End Color: RedRelated Product informationLanthanum- tungsten electrode has become the most favored electrode material globally, especially for the type with 1.5% of lanthanated tungsten.Proven by scientific research, the electric conduction of 1.5% of lanthanated tungsten works as almost efficient as 2.0% of lanthanated tungsten. Therefore, welders are capable of changing electrodes easily instead of adjusting specification of the device.The year of 1998 witnessed an famous experiment in whicn 2.0% thorium tungsten electrode, 2.0% cerium tungsten electrode and 1.5% lanthanated tungsten electrode provided by two manufacturers were tested through welding on the site with respectively 70 amperes, 150 amperes and 300 volt DC electricity. The test result showed that the 1.5% lanthanated tungsten electrode performed outstandingly under both situations and its low rate of buring also caught eyes.The lanthanated tungsten electrode is also suitable for AC welding. product brand Tensileweld/OEM Product color Sky blue product material Tungsten / Tungsten Alloy AdvantageBetter mechanical cutting performance * Better creep resistance * High recrystallization temperature * Good ductility.Cerium-Tungsten Electrode WC201.Cerium-Tungsten ElectrodeItem CodeOxide AddictiveImpurities Content%Tungsten Content%Color StandardStandardWL20VarietiesContent%La2O31.80-2.20<0.2Bal.Sky BlueISO6848AWS A5.12M2.Selection of Tungsten ElectrodeDiameter of ElectrodeNormal DirectCurrentOpposite DirectCurrentDissymmetrical Alternating CurrentSymmetrical Alternating CurrentIn inchmmWPWThWPWTh0.0200.55-20--5-155-2010-205-200.0401.015-18--10-6015-8020-3020-600.0601.670-1510-2050-10070-15030-8060-1200.0932.4150-25015-30100-160140-23560-130100-1800.1253.2250-40025-40150-210225-325100-180160-2500.1564.0400-50040-55100-275300-400160-240200-3200.1874.8500-75055-80250-350400-500190-300290-3900.2506.4750-100080-125325-450500-630250-400340-5253.Electrode Type & Polarity Depending On The Welded Material 1best 2better 3not recommendedMatericalElectrode TypeDCACNeg.Pos.

It is the electrode added with 1-2% of LaO, The power of its electronic transgression is 2.7-2.8ev. Bearing the closest features to those of thorium-Tungsten Electrode. Its arc features and burn spoilage endurance are better when used in small or medium currents condition.Lanthanum-Tungsten Electrode is the most promising substitution product of thorium-tungsten electrode because of its nonradiation. Its another advantage is the endurance of high current but low burn spoilage rate.
