Shielded metal arc welding (SMAW)
Shielded metal arc welding (SMAW)
Shielded metal arc welding is performed by striking an arc between a
coated-metal electrode and the base metal. Once the arc has been established,
the molten metal from the tip of the electrode flows together with the molten
metal from the edges of the base metal to forma sound joint.
This process is known as fusion.
The coating from the electrode forms a covering over the weld deposit, shielding it from contamination
Shielded metal arc welding (SMAW). therefore the process is called shielded metal arc welding. The main advantages of shielded metal arc welding are that high-quality welds are made rapidly at a low cost.
