It is a flexible welding process suitable for all position welding, given the correct filler material and flux composition. Being highly productive due to the high deposition rates, it provides high quality welds with a good appearance. The high welding speed and portability of this welding method means that it is widely used in construction. This is further supported by the fact that the process can be readily performed outdoors, even in windy conditions. Since it can be used to for a range of alloys, plain carbon, stainless and duplex steels, flux cored arc welding is also frequently used for surfacing and hardfacing.
