Flux cored arc welding (FCAW)

Today I will be discussing on flux cored arc welding (FCAW), its applications and how it works. Previously, some article was published on types of arc welding process. Check out!

What is Flux cored arc welding (FCAW)

Flux cored arc welding (FCAW)

Flux cored arc welding is another type of arc welding process that uses consumable electrode that contain flux around it. it is known as semi-automatic or automatic arc welding process. The coalescence of metal is produce by heating with an arc between continuously fed electrode and the base metals. The shielding is obtained by the flux in the electrode. Additional shield may and may not be added from an externally supplied inert gas. That is, shielding gas is supplied from an external source such as gas cylinder or a shield flux coated around the electrode which is deposited when melted.

The flux melts together with the electrode during the welding process and shield the joint, granting the entire weld area with shielding gas. It protects the welds pool from atmosphere.


The followings are the applications of FCAW:

  • This arc welding process is find important in shipbuilding industry as it save huge labour cost.
  • It is also used in many construction industries in welding aspect.
  • It is widely applicable in mechanical industries.
  • FCAW can be used on plain carbon, alloy, stainless and duplex steels.
  • It is used for hard facing and surfacing.

How FCAW works

Unlike other arc welding process that uses AC or DC power supply, FCAW supplies power from DC electric arc to the welding gun. The arc is produce when the gun is struck between the continuously fed consumable filler wire and the workpiece. It create the weld pool and bond when the pool solidifies.

  1. It was a great learning experience am Augustine Ohon from Kenya loved the machine I think it is perfect for Africa and also for someone who is starting a welding workshop
