Shielded Metal Arc Welding (SMAW)

An arc welding process that produces a coalescence of metals by heating them with an arc between a flux covered metal electrode and the workpieces. Shielding is obtained from the breakdown of the electrode flux covering during the welding operation.

Industry applications:
 - Structural Steel
 - Pipe Welding and Fabrication
 - Maintenance and Repair

Flux Cored Arc Welding (FCAW)

An arc welding process that produces coalescence of metal by heating them with an arc between a continuous filler metal electrode and the workpeices. Shielding is provided by a flux contained within the tubular electrode. Additional shielding may or may not be obtained from an externally supplied gas or gas mixture.

Industry applications:

 - Structural Steel
 - Pipe Welding and Fabrication

Gas Metal Arc Welding (GMAW)

Arc welding process that produces coalescence of metal by heating them with an arc between a continuous filler metal electrode and the workpieces. Shielding is obtained entirely from an externally supplied gas.

Industry applications:
 - Light Gauge Fabrication
 - Auto Body
 - Sheet Metal
 - Motorsports

Gas Tungsten Arc Welding (GTAW)

An arc welding process that produces coalescence of metals by heating them with an arc between a tungsten electrode (non-consumable) and the workpeices. Shielding is provided by an externally supplied gas or gas mixture. The use of filler metal may be required for certain applications.

Industry applications:
  - Light Gauge Fabrication Auto Body
  - Customer Fabrication
  - Aerospace
  - Petrochemical
  - Motorsports

Laser Beam Welding (LBW)

A welding process that produces coalescence of materials by heating, with the heat obtained from the application of a concentrated coherent light beam focused into the joint.

Industry applications:
 - Medical Device Manufacture
 - Aerospace
 - Automotive Manufacturers
 - Mold Repair

Robotic Gas Metal Arc Welding (Robotic GMAW)

In robotic gas welding therobot controller operates the entire robotic system. This includes the welding equipment.

All desired robotic movements are programmed and stored by using a teach pendant. Once the program is finalized, robotic operation is initiated via the start button on the controller.

As in manual gas metal arc welding, an electric arc between a continuously fed metal electrode and the base metal produces heat melting the base metal and the electrode, creating the weld.

Industry applications:
 - Automotive Manufacture
 - Production Structural Steel
 - Light Steel Fabrication Prodcution
