In the Tig welding technique, electrodes are used with a diameter of 0.25 - 6.35mm, a length of 70-610mm and surface cleaned with a solution or grinded. Please contact JLC for any other special grades of Nickel based MIG & TIG Wires. Access SmartBlog Category. That electrode is cooled without protective gas can lead to oxidation and turn into yellow, resulting in weld quality. Tungsten electrodes offer high-temperature resistance, which helps them transfer welding current to an arc. When conducting welding with DC current or alternating AC current, the electrode tip should be hemispherical. Electrode grinding should follow the manufacturer's instructions to limit electrode overheating. The best grinding height should be between 1.5 and 3 times as long as the diameter of the electrode. How do I select an amperage level for TIG Welding? These diameters are inch measurements but we will show the metric conversion as well. Below are some of the most commonly produced tungsten welding electrodes for TIG DC, TIG-AC, and Plasma welding: 2% THORIATED (RED) EWTh-2/WT20. `vhVn5~ @hmnq17?`LC1euX{gTi# }uWMJLF?B!

Tungsten is hard and has high temperature resistance and the highest melting point of 3,410degrees C. The tungsten electrodes are available in various sizes and lengths. Cerium tungsten electrodes are used for welding small parts under low current DC conditions. GTAW, or TIG, welding uses a tungsten electrode to form an arc with the workpiece using an inert gas, generally argon or helium. This tungsten electrode contains about 0.3%zirconium oxide, called zirconia. ER- An electrode or filler rod that is used in either a MIG wire feed or TIG welding. Thus, they offer the best dc welding arc starts and stable arc, low erosion rate, wide amperage range, and no spitting. The tungsten is the electrode. 3 0 obj For example, the circular grinding and electrode method is applied when welding with AC current and the sharpening method is used for DC welding. An arc is created between the electrode and the workpiece, and the heat from the arc melts the workpiece material to create the weld. Acetone wipe to remove all cutting oils. Each will typically list which oxides are present in the rod. ; 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. stream Welder by trade for a decade and more. The welding processes which we will explore in the context of amperage selection are these three main processes: TIG (Gas Tungsten Arc Welding, or GTAW), MIG (Gas Metal Arc Welding, or GMAW), and Stick (Shielded Metal Arc Welding, or SMAW). Tungsten is a rare metallic element with the highest melting point of any metal, 3,410 degrees Celsius. Note: RBA1400D is AC 110V OR AC 220V voltage input . 1 0 obj Principal Oxide: 1.7-2.2% Thorium Oxide. Although thoriated electrodes tend to be the favorite for a one-size-fits-most welding approach, some electrodes are better for particular metal combinations. Lanthanted Electrode EWLa-2 (WLa 20) [Code Color: Blue] endobj Additionally, many welders have their own preferences that fit their unique situations. If you only own one size of each type of rod you need, a 3/32" rod should probably . Therefore, we are discussing an obvious replacement for 2% thoriated electrodes. We are exploring all the subjects one by one, and we are also doing reviews of welding gear. 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.

TIG Welding: A Guide to Choosing the Right Tungsten. in tig welding secifications for ti ein. 1.5 mm diameter Tungsten Electrodes that are 59 mm (2.33 in) in length. Pure tungsten electrodes, as their name states, contain 99.50% tungsten. 1mm / 0.04in >Type: Pure Tungsten Electrode (WP) The type of skin of the drug: Tungsten Welding current selection: DC: Connect to negative 15-80 (A) AC: Asymmetrical Waveform 10-80(A) Symmetrical Waveform 20-60(A) Length: Approx. High Frequency. Lift Arc. One of the longest electrode lifespans, with less re-grinding needed than usual. Lift Arc requires touching the workpiece and lifting the torch to initiate the weld cycle. Thoriated tungsten electrodes contain a minimum of 97.30 percent tungsten and 1.70 to 2. After pulling strings or bars, the surface will be cleaned with appropriate solutions. EWLa-1.5 designates TIG electrodes containing 1.31.7 wt.-% dispersed lanthanum oxide (La2O3). There might be affiliate links in this post. Lanthanated electrodes are often considered as an alternative to thoriated electrodes since they show similar characteristics when using inverter or transformer-based AC or DC processes. However, this zirconiated electrode has no commercial importance in the United States. The TIG rods can vary in size and thickness. Single button allows for easy process selection changes. The use of semiconductor poles allows the electrode area to heat more, requiring larger material surfaces to limit the current density. We are trying to make quality articles filled with facts and suggestions for new and seasoned colleagues. The purpose of the addition is to enhance the nature or characteristics of the arc, as defined by the manufacturer. Although no additive is specified, the manufacturer must identify any specific additions and the nominal quantities added. For special applications we have different size electrodes also. Can be used pretty much any material in AC or DC output. From left to right, the name means: E = Electrode. Most of the carbon steel is welded using an E7018 stick rod or ER70S-6 TIG/ MIG filler. TIG welding is an arc welding process that operates at more than 6000 F (3315 C). In contrast, low currents make it easy to corrode electrodes, low temperatures and unstable arcs. TIG arc starting and arc stability from a consistently prepared tungsten electrode are beneficial to the TIG welder. })D4D{ 5YpW\$4J,V!RvJSIh&59XC4V6MUJ=hr 3 N &q+&Gy F^G.
