Narrow Gap


SAW NARROW GAP

Applications

Narrow Gap process used for welding thick plates, mainly for the following industrial applications:

  • Power Generation,
  • Nuclear,
  • Pressure Tanks,
  • Windmill,
  • Petrochemical.

Process
It is a Submerged Arc process with single or tandem narrow gap torch, designed to weld thick plate (generally over 50 mm) using practically parallel sides and narrow gap preparation. Narrow gap process allows to increase productivity and to result in lower cost welding by decreasing the volume of metal needed and the welding time compared to conventional preparation with bevel. The process is adapted for both longitudinal and circumferential welding.
