Flux-cored arc welding (FCAW) is a technique that uses an electric current to melt the flux and bond two pieces of metal together. This is a type of semi-automatic or automatic arc welding. Due to its fast welding speed and mobility, this method is commonly employed in construction.

Flux Cored Arc Welding
Some of the advantages of flux cored arc welding are:
1. Metallurgical Benefits from the Flux
The slag contains elements that can improve corrosion resistance, toughness and crack resistance in welds.
