In the context of LA City certification, what does FCAW-SS stand for?

FCAW-SS stands for Flux-Cored Arc Welding - Self Shielded. This term is significant in the context of welding processes, particularly in the field of structural steel welding as outlined in the Structural Welding Code – Steel (D1.1).

Self-shielded flux-cored arc welding utilizes a tubular wire filled with flux that releases shielding gases during the welding process. This eliminates the need for an external shielding gas supply, making the technique effective in outdoor conditions where wind could affect the stability of shielding gases. Self-shielded FCAW is thus highly valued for its versatility and efficiency, especially in various environmental conditions.

Understanding this terminology is essential for welders and inspectors working in contexts requiring compliance with specific codes and regulations, such as the LA City certification. It relates directly to the methods and materials employed in steel fabrication and construction, emphasizing the importance of proper classification in welding practices.
