Manual Metal Arc Welding (MMA)

Manual Metal Arc Welding (MMA) Overview

Manual metal arc welding (MMA or MMAW), also known as shielded metal arc welding (SMAW), flux shielded arc welding or stick welding, is a process where the arc is struck between an electrode flux coated metal rod and the work piece. Both the rod and the surface of the work piece melt to create a weld. It is a versatile process that can be used on a variety of materials and material thicknesses.
