What Is Shielded Metal Arc Welding and How Does It Work?

TL;DR

Shielded metal arc welding (SMAW) is a process where the welding arc is protected by a flux coating, which enhances the welding quality by providing a shielding gas and slag. This method produces strong welds, is suitable for materials like cast iron and steel, and requires specific power supply equipment and protective gear for safe operation.
