Features :
  • Optional to choose standard or customized mechanism according to work piece size.
  • Suitable for TIG, MIG/MAG, PAW PLASMA+TIG welding process;
  • Suitable for various materials, such as carbon steel, stainless steel, titanium alloy and aluminum alloy etc.;   Suitable for welding longitudinal seams of 0.4mm-12mm wall thickness tank and plates;
  • Use copper-made finger clamp to achieve small welding distortion and high welding quality;
Application :

Cryogenic LNG Cylinder
Features :
  • Customized production line is optional according to production volume
  • 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 welding
  • Mature application experience
  • Over 200 systems are used by existing customers
  • Patent design of i-Control control center, SIEMENS PLC
  • 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
  • Specially-designed longitudinal and circumferential seam welding fixture, convenient for operation, with high productivity and high welding quality
  • Touch screen operation, Chinese/English language
Storage Tank
Features:
  • Modular design to minimize design and production period
  • More than ten years PAW application experience with mature welding procedure instruction and service capability
  • Compatible with storage tank overalll production line and successfully used in 4 customers in China
  • PAW+TIG combination welding, i.e. plasma keyhole process for root pass and TIG process for covering, full penetration with nice appearance and up to 1.5 times faster than single torch welding
  • Stable PLC control platform to ensure longtime working
  • The welding production uses 2 units of plate-to-plate longitudinal seam welding systems + 1 unit of internal longitudinal seam welding system + 2 units of circumferential seam welding systems to achieve 10~12 units of standard storage tanks
  • Turnkey project basis
  • Use of Plate-to-plate longitudinal seam welding system, Internal longitudinal seam welding system, and Cicumferential seam welding system to build up storage tank welding production line
