What is the specification for SMAW low-alley steel electrodes? AWSA5.1 NWSA5.4 c Aws as.6 AWS A5.6

The correct answer is AWS A5.1.The specification for Shielded Metal Arc Welding (SMAW) low-alloy steel electrodes is covered by the American Welding Society (AWS) standard AWS A5.1.This standard provides the requirements for the classification, chemical composition, mechanical properties, and performance characteristics of low-alloy steel electrodes used in the SMAW process.The other options provided are not the correct specification for SMAW low-alloy steel electrodes:- NWS A5.4 is not a valid standard.- AWS A5.6 covers the specification for carbon steel electrodes for gas shielded arc welding (GMAW), not SMAW.- AWS A5.6 is not standard.Therefore, the correct specification for SMAW low-alloy steel electrodes is AWS A5.1.
