Understanding the Flux Core Welding

Flux core welding is popular in various industries for different applications. It is a type of arc welding mostly similar to Metal Inert Gas (MIG) welding. Despite its similarity withMIG welding, it still has unique characteristics that set it apart from other welders—the complete detail of this fantastic welding technique and its pros and cons. Let’s spare a minute to read it!

What is Flux Core Welding?

Flux-core welding, a flux-cored arc welding (FCAW), is a welding technique in which an electrode wire is used. Shielding gas is released while heating the flux, protecting the molten metal from contamination. Therefore, there is no need for external shielding gas in this process. The flux also provides additional protection to the weld by creating slag around the weld bead.

The process of flux-cored welding can be operated with the following two variations:

Self-shielded flux core welding (FCAW-S):

In this variant, the flux in the wire generates the shielding gas. It is most suitable for outdoor applications where the wind could disperse the gas from a gas cylinder.

Gas-shielded flux core welding (FCAW-G):

In this method, an external shielding gas is required. This shielding gas is usually a mixture of carbon dioxide (CO2) and argon. It protects the weld pool from atmospheric contamination.

How does Flux Core Welding differ from MIG Welding?

Although flux core welding is similar to MIG welding, some fundamental differences still affect the performance of welds. Let’s discuss the differences between flux core welding and MIG welding.
