In arc welding an electrode is used to conduct current through a workpiece to fuse two pieces together. Depending upon the process, the electrode in Welding is either consumable, in the case of gas metal arc welding or shielded metal arc welding, or non-consumable, such as in gas tungsten arc welding. For a direct current system the weld rod or stick may be a cathode for a filling type weld or an anode for other welding processes. For an alternating current arc welder the welding electrode would not be considered an anode or cathode. A Welding electrode is a metal wire that is coated. Welding Electrode is made out of materials with a similar composition to the metal being welded. There are a variety of factors that go into choosing the right electrode for each project. sourcensave is an Online One Stop Shop for all welding electrodes and Welding and allows you to shop from a variety of Top Genuine Brands like Ador, ESAB, D&H Secheron, Mangalam, Superon etc. sourcensave aims to bring about a significant transformational change in the Indirect material supply chain by cutting down inefficiencies and bringing in predictability through a suite of value added services.
