what is SMAW – Shielded Metal Arc welding?

what is Shielded Metal Arc welding? Welding can be defined as “operation that produces coalescence of two or more members by applying heats or pressure or both, with or without the use of filler metal.” In fusion welding, members to be joined (base metals) are heated to melt with or without the use of filler metal (e.g. covered electrode), and then the molten parts produce coalescence of the base metals, followed by solidification. In pressure welding, the joining parts are given the thermal energy by friction or gas flame, and then mechanical pressure is applied to complete the welding process.[…]
