This article describes the process, advantages, limitations, applications, and equipment used for shielded metal arc welding (SMAW). It provides information on the types of electrodes, weld schedules, and welding procedures. The article explains the electrodes used in the SMAW process that have different compositions of core wire and a variety of flux-covering types and weights. It includes information on gravity and firecracker welding and discusses dry and wet types of underwater welding. Finally, the article reviews the safety considerations to be followed during SMAW.
