Electric Welding Types and thier Operations

Shielded Metal Arc Welding (SMAW) Operation One reason for the wide acceptance of the SMAW process is the simplicity of the operation of the machine and the necessary equipment. Welding is performed with the heat of an electric arc that is maintained between the end of a coated metal electrode and the work piece (See Figure 1). The heat produced by the arc melts the base metal, the electrode core rod, and the coating. As the …
