Submerged Arc Welding at a Glance

Submerged arc welding is a process of welding that uses an electric arc between  the consumable wire and the base metal blanketed with granular flux. SAW is a process for joining metals. It is used extensively in the ship-building industry.

The S.A.W process was developed in the early 1900s and became popular in the 1940s. The process is used to weld different types of metals like steel, stainless steel, aluminum, copper, brass, nickel and other alloys.

The process has been adopted by many industries because it provides high quality welds with less distortion than other processes like gas metal arc welding or shielded metal arc welding. It is also more economical than other processes because it can be automated and requires less labor than manual welding methods.

The S.A.W process has many benefits over other welding processes, such as being faster and more economical than gas metal arc welding. It also produces less fumes and slag. The downside to this process is that it requires more skill from the welder than other processes.
