At their best, rare earth electrodes can ensure stable arc, longer life, and a current that rivals other electrodes, even though they are usually smaller. There are various tungsten electrodes that you can use for the process, but not all will prove efficient. The thickness of the rod determines the amount of filler metal deposited after you dab it in the weld pool, but it also determines the amount of energy needed to melt that rod diameter. The oxide enhances arc starting and stability, reduces tip erosion rate, and extends the current operating range. Purple tungsten electrodes are the perfect mix between benefits and safety. These rods, however, are generally used for fill and cap passes on cross country pipe, when a 5/32" is used for the root and hot pass. You need to select a diameter large enough to accommodate the maximum current used for each welding job. Type: Cerium Tungsten Electrode (WC20). These electrode's deposit strength is higher than most commonly used carbon steel such as ASTM A36, ASTM A 516, S275 or S375, ASTM 105 . 5 = The aluminum series 5,000 that makes up the electrode wire. Best for use on non corroding steels . Tungsten Inert Gas (TIG) welding is a popular type of welding that utilizes tungsten electrodes to join various metals. 3 0 obj

The best size and type of electrode depends on your preference and your application. Non-consumable electrodes come in a variety of sizes, electrode diameters, and lengths. Tungsten electrodes offer high-temperature resistance, which helps them transfer welding current to an arc. Required by customers to weld different metals, such as aluminum, stainless steel, etc. Selection of Correct Size of Electrode. All values are based on the use of Thoriated, Ceriated, or Lanthanated Tungsten electrodes with argon gas. Compared to other electrodes that are subject to AWS classification, the manufacturer may select any color not already in use. . 1/8 inch: high current; 180 to 300 DC amps, 150 to 240 AC amps. The positive characteristic of tungsten makes it a foundation of Tungsten Inert Gas (TIG) welding. Please contact JLC for any other special grades of Nickel based MIG & TIG Wires. . The grinding should be done straight and not at 90 degrees. There might be affiliate links in this post. TIG (tungsten inert gas) electrodes each insert into a compatible TIG torch that is connected to a TIG welder that supplies current to the electrode. It also means we can grind the electrode tip to a sharp, conical point to concentrate the arc, and it won't deteriorate quickly. Additionally, many welders have their own preferences that fit their unique situations. ; 6- The amount of deoxidizing agent and cleansing agent on the electrode.This is a copper coating on the electrode and there are different types too. Pick Up Your Free Stick Welding Electrodes Chart That We Made! But, again, the manufacturers warnings should be followed, especially when grinding thoriated tungsten. Specification: Item Type: Rod Tungsten Electrode Material: Pure Tungsten Core Diameter: Approx. EWLa-1.5 designates TIG electrodes containing 1.31.7 wt.-% dispersed lanthanum oxide (La2O3). As a YesWelder affiliate, I earn commissions for qualifying purchases. As a general rule of thumb, for welding steel on AC or DC, use 2% thoriated tungsten electrodes (larger is better). Stick Electrode Selection Sheet MST 140i MST 180i MST 220i TIG 140 ACDC TIG 200 ACDC TIG 160S ELECTRODES Up to 3/32" Up to 5/32" Up to 5/32" Up to 3/32" Up to 5/32" Up to 5/32" .
