What is the AWS specification number for FCAW, carbon steel electrodes?

The American Welding Society (AWS) specification number for Flux-Cored Arc Welding (FCAW) using carbon steel electrodes is A5.20. This specification outlines the requirements for the classification of carbon steel electrodes that are used in the FCAW process, which is important for ensuring the quality and performance of welds in various applications.

Understanding the significance of this specification is crucial for welders and engineers as it provides guidelines on types of welding consumables, including mechanical properties and deposition rates. The specifications help in choosing the right electrodes for specific welding conditions and ensure compliance with code requirements, ultimately leading to safer and more durable welded structures.

The other options pertain to different categories of welding consumables. For example, A5.25 covers the classification of electrodes for gas-shielded FCAW, A5.16 addresses submerged arc welding, and A5.14 is for metal cored electrodes for welding. Each specification serves a specific purpose within the welding industry, but A5.20 is the correct reference for FCAW utilizing carbon steel electrodes.
