Today i will be discussing on the working principles of flux cored arc welding (FCAW). I will also enlighten on its advantages and disadvantages. Previously, an article was published on What is FCAW, and it applications. Check out!
Working principles of Flux cored arc welding (FCAW)
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.
Watch video on the working principles this process:
The following are the advantages of FCAW;
- It has different ways of supplying shielding gas
- It may be applied to all welding position
- Shielding gas is not needed for some its wires are suitable in windy conditions
- It has high deposition rate
- Chances of porosity are very low
- Less cleaning of base metal
Despite the great benefits of FCAW, it still offers some disadvantages. The following are the limitations of this welding process.
- It produces slag, which must be removed after welding
- It produces more smoke which is hazardous to the welder
- Cost of applied wire
- It Is complex and more expensive
- It produces more spatter
- What is electric arc welding, its applications, advantages and disadvantages?
- Different types of electric arc welding process
- Safety precautions in arc welding operation
- Working principles of arc welding process
And that is it for this article, working principles of flux cored arc welding, it advantages and disadvantages. I hope you enjoy reading this. If so, comment and share. Thanks for reading!
