Customer Success Stories

Teamtechnik: SmartWeld+ Fills the Gaps in Production Welding

When production automation experts teamtechnik were contracted to develop a production welding system, they looked to Coherent to supply the laser expertise. They ended up with a partner who helps them provide their customer with ongoing support.

"SmartWeld+ gives us great results and can readily adapt to make process changes. But the real reason we went with Coherent is their support. No other supplier was willing to do the development work necessary to ensure we could satisfy our end user’s requirements."
