Case Study: TRUMPF boosts welding productivity and quality with Alma CAM

The Haguenau TRUMPF Factory On The Path To Industry 4.0 With Robotized Welding

TRUMPF’s Haguenau plant in France, a strategic site producing frames for punching and laser cutting machines, needed to modernize welding operations to boost productivity, improve quality, and prepare for Industry 4.0. With experienced welders nearing retirement and increasingly complex products, the company turned to Alma CAM for offline programming software to support robotized welding.

Alma CAM implemented offline programming for a Yaskawa twin-robot welding cell, helping TRUMPF simulate and optimize complex welding paths, including sensing for large assemblies. The result was a faster, more stable process: TRUMPF cut frame lead times from 25 days in 1994 to about 10 days, and in the new robotic cell achieved roughly 4.5-hour cycle times, with plans to reduce this to 4 hours. The project also reduced weld deformation from 5–6 mm to zero and enabled TRUMPF to scale the approach to additional frame types.
