Laser Station ЛКТТД

Laser station ЛКТТД-01 was developed to solve the task of welding tubes to tube plates in heat-exchanges. The station implements fully automated welding process with automatic adjustment to tube centre.

The station comprises the following components:

  • fiber laser of 1000–2500 W depending on the material of plate and the fusion depth
  • mobile welding station
  • welding head VF001 with nozzle system ensuring the welding process and protection of metal, including titanium alloys
  • digital videosensor ensuring referencing to object and adjustment to tube centre
  • control system.

The station control system is built on the basis of network computer numerical control (CNC) of PAC©InSoft architecture using separate processor modules for every piece of equipment (servo drive, laser head, gas regulator, etc.) united in one network by CAN interface. This solution ensures minimization of cabling and high reliability of operation.
