Bonding of large-diameter, long parts is possible.

Improved productivity

  • Parts are set quickly and with ease using rod and head (material) mounting device.

  • Quality can be controlled with a PC-based quality assurance device (condition management visualization, waveform display function).

  • Unmanned operation and automation are possible when used in conjunction with an auto loader.

Improved quality

  • Ideal, high-durability is obtained for “weld penetration” of bonded parts.

  • Thermal distortion is minimal, and high dimensional accuracy is obtained.

  • No spatter is produced, resulting in clean finishing.

Cost reductions

  • The machine is equipped with a cutting device, eliminating the need for a deburring post-process.

  • Thermal distortion is minimal, eliminating the need for rod head correction.

  • Power consumption is 1/5 to 1/20 of that of other welding methods.

Improved environment

  • CO2 emissions can be reduced.

  • No toxic substances such as sparks or gas are produced.
