AMADA & MILLER Welding Work Station Processes
Gas metal arc welding (GMAW), sometimes referred to by metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metals, which heats the workpiece metals, causing them to melt and join. Along with the wire electrode, a shielding gas feeds through the welding gun, which shields the process from contaminants in the air.
Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.
Resistive spot welding (RSW) is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current. Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.12 in) thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small 'spot' and to simultaneously clamp the sheets together. Forcing a large current through the spot melts the metal and forms the weld. Spot welding is mainly used when welding particular types of sheet metal, welded wire mesh or wire mesh.
AEI Lighting forms and assembles thousands of aluminum, steel and alloy lighting fixtures every month and has expertise in all ranges of fixture assembly, from steel components to various weldments to punched/formed aluminum and alloy architecture to fixture wiring/wireways for lighting components.
