• Plasma Arc Welding Safety When plasma arc welding, safety is an important consideration. Plasma arc welding is a process in which coalescence is produced by heating with a constricted arc between an electrode and the work piece (transfer arc) or the electrode and the constricting nozzle (non-transfer arc). Shielding is obtained from the hot... Read more >>
  • Shielded Metal Arc Welding (SMAW)  Shielded Metal Arc Welding (SMAW) *Shielded Metal Arc welding *is the most widely used method for general welding applications. It is also referred to as metallic arc, manual metal-arc, or stick-electrode welding. It is an arc welding process in which the joining of metals is produced by heat from an electric... 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...

  • Arc Welding Aluminum : How to Stick Weld Aluminum When arc welding aluminum with the shielded metal-arc welding (SMAW) process, a heavy dipped or extruded flux coated electrode is used with DC Reverse Polarity (DCRP). The electrodes are covered similarly to conventional steel electrodes. The flux coating provides a gaseous shield around the arc and molten aluminum puddle, and chemically... Read more >>
  • Carbon Arc Welding (CAW) Carbon arc welding is a process in which the joining of metals is produced by heating with an arc between a carbon electrode and the work. No shielding is used. Pressure and/or filler metal may or may not be used. Carbon Arc Welding Equipment Electrodes. Carbon arc welding electrodes range... Read more >>
  • Arc Welding Definition Arc Welding Definition. In the arc welding process, the weld is produced by the extreme heat of an electric arc drawn between an electrode and the workpiece, or in some cases, between two electrodes. Welds are made with or without the application of pressure and with or without filler metals.... Read more >>
  • Arc Welding Electrodes Arc 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, which protects the... Read more >>
