AEI Fabrication has almost two decades of experience in the sheet metal welding and assembly processes. AEI's AMADA and Miller welding work stations and trained technicians are capable of handling small, mid-sized and large production jobs at the most detailed specifications and stringent of certifications.  AEI Fabrication can perform MIG, TIG and spot welding for your project and meet all of your product assembly needs.
 

 AMADA & MILLER Welding Work Station Processes

MIG WELDING

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.  

 

TIG WELDING

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.

 

SPOT WELDING

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.

 

ASSEMBLY

AEI Fabrication has expertise in all ranges of product assembly, from steel components to various weldments to punched/formed aluminum and alloy architecture for components (electrical, lighting, other).  AEI Fabrication forms and assembles thousands of aluminum, steel and alloy products and fixtures every month.
