Application Cryogenic LNG tank etc.

Feature:

  • Specially-designed longitudinal and circumferential seam welding fixture, convenient for operation, with high productivity and high welding quality
  • PAW keyhole process for thickness 3~8mm without bevel requirement to achieve single-side welding double-side forming and small distortion, which is 4~5 times faster than manual TIG welding
  • Internal cylinder: high-efficient pulsing MAG welding process for longitudinal/circumferential seam, or PAW for longitudinal seam welding + MAG for circumferential seam welding; External cylinder: high-efficient pulsing MAG welding process for longitudinal seam welding, or TIG with wire feeding for longitudinal/circumferential seam weldin
