Rauch Landmaschinen has turned welding robot programming from a bottleneck into a competitive advantage.

The Challenge

Rauch Landmaschinen, a leading German manufacturer of agricultural machinery, has been using robotic welding systems for decades. With a high mix of parts, frequent new designs, and small batch sizes, programming welding robots quickly and reliably was a constant challenge.

“The biggest challenge with our robotic welding systems has always been the time-consuming task of creating robot programs,” explains Michel Gasser, Welding Shift Leader with 34 years of experience in welding and welding robotics at Rauch.

For Tobias Peter, Head of the Welding Department, the situation was clear:

“Many new designs with small batch sizes made it difficult to use welding robots effectively.”

The Solution: ArcNC

With the adoption of ArcNC, Rauch found a way to overcome these limitations.

ArcNC extracts weld seams and plans robot motions automatically, while integrated “Sense Motions” measure the part when needed, ensuring high accuracy. This significantly reduces programming time and improves quality.

“The programs generated with ArcNC are of such high quality and precision that we are step-by-step replacing our old online-programmed robot programs,” says Gasser. “The improved repeatability is largely thanks to the Sense Motions.”

Another major benefit: reduced downtime.

“The robots themselves are not used differently, but because we don’t program robots with the teach pendant anymore, we save enormous amounts of downtime on the systems,” adds Peter.

Favorite Features

Both leaders highlight the same strengths:

• Automatic program generation and optimization – programs can be adapted manually if needed.
  
  
• Sense Motions – ensure accuracy and repeatability by measuring parts.
  
  
• Flexibility – ArcNC handles both single parts and large series with equal efficiency.
  
  
• Close collaboration – ArcNC’s team responds quickly and implements customer feedback directly.
  
  

“What I like best is the combination of high flexibility, excellent collaboration, and the fast implementation of our suggestions,” says Peter.

The Results

With ArcNC, Rauch has transformed its welding department:

• Faster programming – free up engineering time for other tasks
  
  
• Less downtime – higher machine availability.
  
  
• Higher precision and repeatability – improved welding quality.
  
  
• Scalable efficiency – equally effective for small batch runs and larger series.
  
  

Recommendation

Both Gasser and Peter would recommend ArcNC to companies with complex welding needs:

• Gasser: “Machine builders who weld many different parts will benefit most. ArcNC writes the program immediately – no matter if it’s for a one-off part or for a large series.”
  
  
• Peter: “Anyone struggling with small batch sizes and frequent new designs will gain a clear advantage.”
