Applications

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

Advantages

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

Disadvantages

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.
