Flux cored arc welding
Flux cored arc welding
Flux cored arc welding (FCAW), also known as dual-shield welding, is a semi-automatic arc welding process that is similar to metal active gas (MAG) welding. FCAW uses a continuous wire-fed electrode, constant voltage welding power supply, and similar devices as used in MAG welding.
FACW uses the heat generated by an arc to melt the base metal in the weld area. This arc is ignited between the metallic workpiece and the continuously fed tubular cored, consumable filler wire, with both the wire and the metallic workpiece melting to form a welded joint.
Applications:
• Welding of heavy sections in Pressure vessels, • Construction equipment, offshore structures, Bridges • Basic type gas shielded FCW wire • Stable arc, Easy slag removal • Smooth and porosity free welds • Crack resistant and tough welds especially when • welding steels with high carbon content
