GE Detector Tests Spot Welding

The Spotchecker from GE Sensing And Inspection Technologies is a hand-held flaw detector with application-specific software, which allows it to be used as a portable solution for spot weld testing. Contained within an environmentally protected housing, the instrument does not require intensive training and offers an 'expert' system for less qualified people in weld inspection.

Spotchecker will allow inspection to be carried out at the place of welding, rather than having to move welded parts to dedicated inspection points. Spotchecker is sealed to IP65 and weighs 3.5kg. Its ergonomically designed operator interface features an 8in LCD touch screen, six programmable function keys and twin track balls to allow ease of use, even in the most restricted of testing locations. It is battery operated and batteries can be 'hot swapped' to ensure continuous operation.

Battery charging can be done with batteries inside or outside the instrument, using an external charger. The instrument can also be remotely operated if required. The flaw detector can be connected to external periphery devices such as mouse, keyboard and printer either by USB or by WLAN. Data upload and download is performed wirelessly. The Ultralog application software included with Spotchecker is a tried-and-tested database program for the systematic inspection of spot-welded joints.

Combining ultrasonic expertise with electronic data processing, it provides a package for performing inspection, evaluation and documentation of results, while meeting strict quality management requirements. By setting out inspection and test plans, specifying the number of welds to be inspected, and describing the test location material data, test diagrams and ultrasonic settings, Ultralog allows Spotchecker to be used by relatively unskilled personnel.

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.
