Welding, Brazing and Soldering Equipment Information

Welders and welding machines cover devices used in a wide array of joining processes including arc welding (MIG, TIG, stick, submerged arc), resistance welding, laser welding, electron beam welding, stud welding orbital welding, wave soldering, hot dip brazing, torch brazing, induction brazing, ultrasonic and friction welding. Welders and welding machinesincludes the complete devices as well as their power sources, monitors, and controllers used for welding, brazing and soldering.

 

Welders and welding machines can be supplied as a complete system, a welding power source, and a weld monitor or controller.  A complete system includes complete welding, surfacing or cutting machine, equipment or system including power source, torch or gun, cables, feeders, positioners, robots or other required components.  A power source provides a TIG gun, MIG gun, electrode holder, laser, electron beam gun or other welding unit the required output power to melt material. Welding monitors or controllers are instrumentation used for sensing welding quality (nugget size or weld integrity) or output power supply variations. Also, welder controllers used to adjust welding parameters to compensate for variations in weld quality or output power.

 

Arc or resistance welding types that apply to welders and welding machines include, Flux Cored Arc Welding (FCAW), Gas Metal Arc Welding (GMAW), Multi-process, Orbital / Tube Arc Welding, Plasma arc welding, Flash welding, Projection welding, Resistance seam welding, Spot welding, Shielded Metal Arc Welding (SMAW), stud arc welding, Submerged arc welding (SAW), and Gas Tungsten Arc Welding (GTAW).

 

Frictional or other fusion welding types that apply to welders and welding machines include Electron beam welding, friction welding, Hot plate welding and plastic welding, Laser welding, Oxyfuel welding, Thermite or exothermic welding, and ultrasonic or linear friction welding.

 

Output Power Specifications

 

Output power specifications are important to consider when looking for entire systems of welders and welding machines or the power systems for these machines. The duty cycle is the percentage of time a welding unit can remain on in a ten-minute period before powering off to cool and prevent damage to components. Output power capability specifications include AC output, DC output, AC/DC selectable output, and high frequency. The output current range is the designed current range of the welding unit or the current range monitored or controlled. The output voltage range is the designed voltage range of the welding unit or the voltage range monitored or controlled.

 

Features

 

Features common to welders and welding machines include engine driven generators, machine duty or corrosion resistance, multi-operator, and water-cooled.
