Today I will be discussing the applications, advantages, and disadvantages of submerged arc welding Previously, an article was published on submerged arc welding (SAW). Check out!

The followings are the applications of SAW:
SAW process is suitable for welding carbon steels (structural and vessel construction). It is also used on low alloy steels, stainless steels, nickel-based alloys, and surfacing applications.
The followings are the general applications of submerged arc welding:
- It is suitable for longitudinal and circumferential butt and fillet welds
- Ability to weld nonferrous metals
- Base on the material thickness, either single pass or multi-pass welding procedures can be implied
- There is no restriction for material thickness

Advantages and disadvantages of SAW
The followings are the advantages of SAW welding.
- It has a high deposition rate
- The single-pass can be made in thick plates using normal equipment
- Ability to make the deep weld
- Flux can be recovered, recycled, and reused
- It produces welds with sound, uniform, corrosion-resistant, and good impart value
- The arc is covered under a blanket of flux, which gave no chances for spatter
- The process can be performed both indoor and outdoor
- High-speed welding can be done on a thin sheet
- Edge preparation is not necessary
Despite the good benefits of submerged arc welding offers. Some limitations also occur. The followings are the disadvantages of submerged arc welding.
- It is limited to some ferrous metals like steel and stainless steel
- It is also limited to long straight seams or rotated pipes and vessel
- Backing strips are required for proper penetration
- It is limited to high thickness materials.

That is it for this article, where the applications, advantages, and disadvantages of submerged arc welding SAW are being discussed. I hope you get a lot from the reading, if so, kindly share with other students. Thanks for reading, see you next time!
