Mechanised welding.Greater productivity. Greater quality. Lower costs.

Economical automation of welding.

Great physical effort is demanded of the welders where very long weld seams of high quality are required. Mechanised welding is the solution.

Relieved professionals. Warranted high-quality long weld seams.

Mechanised welding can be used, for example, as a partially automated welding application

Increase your welding production performance and connect your Lorch power sources to the Lorch welding tractors. The welding tractor ensures continuous torch guidance while the welder focuses entirely on setting the welding parameters. This increases the welder's productivity and weld seam quality alike. 

Further advantages of mechanised welding.

Mechanised and semi-automated welding has even more advantages: The introduction of heat becomes more controllable and causes less distortion. Repetition and reproducibility reduce stress. The greater distance from the torch improves even the welder’s working situation. 

Advantages and disadvantages of mechanised welding.


  • Reproducible seams 
  • Low rework 
  • Saving production time and consumables 
  • MIG-MAG and TIG applications possible 



  • Not suitable for every application segment 

Mechanised welding with the Lorch modular system.

The Lorch modular system for mechanised welding permits economical automation of small batch sizes with short changeover times. 

The system optimally supports every single step of the welder, as all settings can be made quickly and precisely. The Tiptronic job memory in the power source and control gives the welder a system ready for the welding tasks at hand in a matter of minutes. Handling is a walk in the park for any operator as well. All it takes is inserting the workpiece, pushing the button, and starting the welding process. 

Custom components for your specific projects.

Thanks to the Lorch modular system for mechanised welding, you only need to buy what you actually need for automating your custom welding task: All modules of the modular system interact perfectly and receive your commands via the LorchNet from the LorchControl unit. 

MIG-MAG or TIG? Comparison of mechanised welding.

Mechanised MIG-MAG-welding.

  • Minimal rework and low distortion 
  • Low costs for additional material 
  • Outstanding thin-sheet properties 

Mechanised TIG welding.

  • Spatter free welding 
  • Visually high-quality weld seams 
  • Particularly high weld seam quality

Always well-advised with close, personal, and honest support.
