Applications, advantages and disadvantages of submerged arc welding

Today I will discussing on submerged arc welding applications, its advantages and disadvantages. Previously, an article was published on submerged arc welding. Check out!

Submerged arc welding SAW

Applications

The followings are the applications of SAW welding process:

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

The followings are the advantages of SAW welding.

  • It has high deposition rate
  • The single pass can be made in thick plates using normal equipment
  • Ability to make 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 thin sheet
  • Edge preparation is not necessary

Disadvantages

Despite the good benefits of submerged arc welding offers. Some limitations also occurs. The followings are the disadvantages of this welding process.

  • 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 is required for proper penetration
  • It is limited to high thickness materials
