The advantage of Submerged Arc Welding (SAW) in rotary casing welding

April 10,2024

Submerged Arc Welding (SAW)  is a common welding process used in industrial applications. It involves the formation of an arc between a continuously fed electrode and the workpiece.


Advantages of Submerged Arc Welding:

1. High Deposition Rates: SAW can deposit a large amount of weld metal in a short time, making it suitable for high-production environments.

2. Deep Penetration: The process allows for deep penetration of the weld into the base material, resulting in strong weld joints.

3. High Efficiency: The continuous feeding of the electrode and the use of the flux enhance the efficiency of the welding process.

4. Reduced Emissions: The flux blanket reduces the amount of fumes and spatter, creating a cleaner welding environment.

5. Consistent Weld Quality: Automated or semi-automated SAW systems can produce consistent, high-quality welds with minimal defects.

6. Minimal Post-Weld Cleaning: The slag formed by the flux can be easily removed, reducing the need for extensive post-weld cleaning.

7. Reduced Distortion: The process's high deposition rate and efficient heat input reduce thermal distortion of the workpiece.

8. Adaptability: SAW can be used for welding a wide range of materials and thicknesses, making it versatile for various applications.

Due to the application of automatic submerged arc welding machines in our production of rotary casings, our factory’s capacity of casing can be up to 1000m per month and always maintain stable & high quality welding level for rotary casings.
