In FCAW-SS, what does the 'SS' stand for?

In the context of FCAW-SS, the 'SS' stands for 'Self-Shielded.' This type of flux-cored arc welding does not require an external shielding gas because the flux contained in the cored wire generates a protective shielding atmosphere during the welding process. This makes it particularly advantageous for outdoor applications, where wind could disrupt the effectiveness of shielding gases typically used in other welding processes.

The use of self-shielding allows for increased productivity since additional gas equipment is unnecessary, providing greater flexibility and portability. It is important to understand different shielded welding techniques to choose the appropriate method for specific welding environments and requirements.
