Shielded Metal Arc Welding (SMAW) is a manual welding process where heat is generated by an electric arc between a consumable electrode and the base metal. SMAW has advantages of versatility in applications and positions, simplicity of equipment, and adaptability to confined spaces, but has disadvantages of lower productivity than continuous wire processes, higher costs due to frequent electrode changes, and higher metal wastage from stubs.

Shielded Metal Arc Welding (SMAW) Advantages  Versatility - readily applied to a variety of applications and a wide choice of electrodes  R elative simplicity and portability of equipment  Low cost  Adaptable to confined spaces and remote locations  S uitable for almost all welding positions like Flat, Horizontal, Vertical & Overhead Disadvantages  Not as productive as continuous wire processes (MIG)  Likely to be more costly to deposit a given quantity of metal  Frequent stop/starts to change electrode  Relatively high metal wastage (electrode stubs)  Current limits are lower than for continuous or automatic processes (reduces deposition rate)
