Murex Publishes Guide to Metal Inert Gas Welding

Murex Welding Products has published a guide to metal inert gas (MIG) welding, an arc welding process that is suitable for small fabrications and repairs, large structures, shipbuilding and robotics. MIG can be used on a range of materials and thicknesses. Superpulse technology enables MIG to give a finish that is similar to that obtained with TIG welding, but with faster speeds.

The guide discusses the principles of the process and offers practical advice on how to carry out MIG welding tasks. Murex said ease of use is a major benefit of MIG in many applications, but added that speed is also an advantage as it is quicker to lay down weld metal with MIG than with TIG, MMA or gas welding. Typical applications for MIG include automotive subassemblies and bodywork, ranging from conventional MIG for most bodywork to heavy-duty MIG for lorry chassis and off-highway vehicles, as well as lower-current MIG brazing of thin-gauge, high-strength steels.

MIG is also used extensively in automotive and general repair workshops. Other non-automotive applications include the assembly of white goods and office furniture, the joining of structural steelwork for the construction industry, as well as repair work in ship repair yards and welding tasks in the process industry for pipework and the fabrication of vessels.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
