  • Metal Inert Gas Process (MIG)
    The Gas Metal Arc Welding (GMAW), process is commonly known as the Metal Inert Gas Process (MIG). MIG welding is also referred to as short circuit transfer. In the MIG arc welding process, metal parts are joined by melting base and filler metals with an arc struck between a consumable filler metal
  • Distributed IO can reduce arc flash hazards
    . This blast usually lasts under one second but can reach up to 35,000 F, which can result in severe burns to human skin. Additionally, the arc flash blast can propel molten metal, shrapnel, and tools through the air, causing a serious risk to facility personnel and occupants. The gravity of this danger
  • Stud Arc Welding and Drawn Arc Welding
    discharge, internal resistance, or other processes are used to generate an arc or fuse metal. Similar processes can be applied to weld a thread nut to a work piece. In drawn arc welding systems, an arc is struck between the fastener and work surface, the fastener is then lifted and plunged into the molten
  • "Cold " Laser Beam Improves Arc Welding, Saves Money
    lightning bolts -- melt metals at temperatures as high as 3500 C. Arcs can move unpredictably, Albright said, and sometimes they warp welded parts or splatter liquid metal. "Ever wonder why lightning looks so jagged? " he asked. "When you start an arc, initially there's no telling where it's going to go
  • Spark or Arc Excitation
    Spark and arc excitation sources use a current pulse (spark) or a continuous electrical discharge (arc) between two electrodes to vaporize and excite analyte atoms. The electrodes are either metal or graphite. If the sample to be analyzed is a metal, it can be used as one electrode. Non-conducting
  • Arc-Welded Studs
    In stud welding, the heat of an electric arc drawn between the fastener and the work melts a quantity of metal, after which the two heated parts are brought together under pressure. Welded fasteners must be made of a weldable material, and one end of the fastener must be designed for welding. Stud
  • Guarding against arc flash
    to a loss of eyesight. It can also spew molten metal considerable distances where it can lodge in skin or ignite clothing. A 10,000-A arc on a 480-V circuit is said to have the explosive force of eight sticks of dynamite. The National Fire Protection Agency (NFPA), Occupational Safety and Health
  • Arc Flash: Not My Fault
    when an arc fault superheats the air around it, expanding and creating a pressure wave within an electrical enclosure. Explosions can be as hot as 35,000 F, and can send shrapnel and molten metal flying out from equipment (Figure 1). The NFPA 70E standard dictates the precautions that manufacturers
  • Ultrasonic Metal Welding for Wire Splicing and Termination
    useful application of this technology. Commonly used techniques involving the fusion of metal through the application of heat by flame, hot tools, electric current or electric arc in combination with cleaning and fluxing agents and sometimes filler metals are able to join these materials
  • How do you protect against arc flash exposure in industrial applications?
    a densely-concentrated equipment’s moving parts that are manufactured to clear. blast of pressure formed by light and heat energy. The arc electrical faults, can potentially cause arc flash incidents. flash blast can propel molten metal, shrapnel and tools Lastly, an improperly designed electrical system or sys
