• Tungsten Electrodes Tungsten Electrodes Non-consumable tungsten electrodes for GTAW (Gas Tungsten Arc Welding)  or TIG (Tungsten Inert Gas) welding, generally are of several types.  Tungsten electrodes types and their typical application can be identified by color coded end marks as follows. Pure Tungsten :  Green 2% Ceriated :  Gray 2% Thoriated : Red... Read more >>
  • Underwater Shielded Metal Arc Welding Electrodes Underwater Shielded Metal Arc Welding Electrodes. Commercial manufacturers have made significant progress in the development of waterproofing systems for wet welding electrodes. Details of these systems are proprietary to each manufacturer; however, the results of their cumulative efforts have produced a new generation of wet welding electrodes. Certain electrodes are...

  • Tungsten Electrode Selection Tungsten Electrode Selection The selection and preparation of  tungsten electrodes for TIG Welding or Gas Tungsten Arc Welding (GTAW) to use for a particular application depends on many variables, including the type of  material to be welded, the welding amperage and the type of weld, among other factors. Tungsten Electrode... Read more >>
  • MIG Welding Wire MIG Welding Wire Electrodes used for MIG Welding are smaller than those used for other welding process. This is because of the high current and speed at which the welding filler material is introduced into the weld puddle. Aluminum MIG Welding Wire E4043 is the most common Aluminum MIG Welding...

  • Flux-Cored Arc Welding Electrodes Flux-cored Arc Welding Electrodes The electrodes used for flux-cored arc welding provide the filler metal to the weld puddle and shielding for the arc. Shielding is required for sane electrode types. The purpose of the shielding gas is to provide protection from the atmosphere to the arc and molten weld... Read more >>
  • Arc Welding Electrodes Arc Welding Electrodes In addition to establishing the arc and supplying filler metal for the weld deposit, arc welding electrodes introduce other materials into or around the arc. Depending upon the type of electrode being used, the covering performs one or more of the following functions: Provides a gas to... Read more >>
  • Arc Welding Electrode Classification System ** Arc Welding Electrode Classification System. ** The SMAW electrode classification code contains an E and three numbers, followed by a dash and either “15” or “16” (EXXX15). The E designates that the material is an electrode and the three digits indicate composition. Sometimes there are letters following the three... Read more >>
  • Types of Welding Electrodes  Types of Welding Electrodes  When molten metal is exposed to air, it absorbs oxygen and nitrogen, and becomes brittle or is otherwise adversely affected. A slag cover is needed to protect molten or solidifying weld metal from the atmosphere. This cover can be obtained from the electrode coating. The composition... Read more >>
  • Solid Electrode Wires a. Bare or solid wire electrodes are made of wire compositions required for specific applications, and have no coatings other than those required in wire drawing. These wire drawing coatings have a slight stabilizing effect on the arc, but are otherwise of no consequence. Bare electrodes are used for welding... Read more >>
  • Non-Consumable Electrodes and Other Filler Metals Non-Consumable Electrodes There are other filler metals and special items normally used in making welds. These include the non-consumable electrodes (tungsten and carbon), and other materials, including backing tapes, backing devices, flux additives, solders, and brazing alloys. Another type of material consumed in making a weld are the consumable rings... Read more >>
  • Flux-Cored Welding Electrodes a. The flux-cored arc welding process is made possible by the design of the electrode. This inside-outside electrode consists of a metal sheath surrounding a core of fluxing and alloying compounds. The compounds contained in the electrode perform essentially the same functions as the coating on a covered electrode, i.e.,... Read more >>
