Tungsten Electrodes Guidelines - BWS LTD

Sep 22, 2020 · Tungsten Electrodes Guidelines. TIG welding is an arc process whereby you create the arc with an electrode and add the filler wire by hand. The electrode used is made of tungsten which is a rare metallic element. Tungsten has the highest melting point of any metal, 3,410 °C. Tungsten electrodes come in a varying degree of sizes depending on the material you want to weld and the Tungsten Electrode Market SWOT analysis and market guidelines for tungsten electrodesTungsten electrodes are alloyed with metals such as stainless steels, and nickel. Various sizes of electrodes are used for the different types of materials and welds. Tungsten electrodes perform guidelines for tungsten electrodesThe use of thoriated tungsten electrodes - TWITungsten electrodes are used when arc welding with the Tungsten Inert gas (TIG) process or when plasma welding. In both processes the electrode, arc and weld pool are protected from atmospheric contamination by an inert gas. A tungsten electrode is used because it can withstand very high temperatures with minimal melting or erosion. Electrodes are made by powder metallurgy and are formed to size after sintering. TIG welding electrodes usually contain small quantities of other metallic oxides wSee more on twi-global guidelines for tungsten electrodes

Selecting the right tungsten

For AC welding with a GTAW inverter, the tungsten should be prepared in the same manner as for DCEN welding. Once an arc is established, the electrode shape will be determined by the AC balance and AC frequency. The higher the EN percentage and frequency, the sharper the point will remain.Selecting and preparing tungsten electrodesThe complete electrode geometry for DC welding comprises the electrode diameter, the included angle (taper), and the tip (flat) (see Figure 1). The choice of geometry will always affect electrode life, arc starting, weld penetration, and arc shape. Regardless of the geometry selected, the electrode configuration must be tested during welding procedure development. The geometry should be noted as a critical process variable for the weld See more on thefabricator guidelines for tungsten electrodesSAFETY DATA SHEET (SDS) - Tungsten ElectrodesSAFETY DATA SHEET (SDS) - Tungsten Electrodes SECTION I - IDENTIFICATION OF THE SUBSTANCE OR MIXTURE AND OF THE SUPPLIER GHS product identifier: Tungsten Electrodes for Welding Designation Chemical Composition Impurities 0.2% Tip Color ISO 6848 AWS A5.12 Oxide Additive, % Tungsten, % WT20 EWTh-2 ThO 2
