Flux cored welding, also known as flux cored arc welding (FCAW), is a semi-automatic welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant-volatage.
The process is widely used in construction because of the high welding speed and portability. Flux cored welding robotics are commonly used on mild and low alloy steels, stainless steels, some high nickel alloys and some wearfacing/surfacing alloys.
