Anyone searching for a German laser manufacturer will find three types of companies, but only one group actually builds complete welding systems for production use. In the workshop, a buyer looking for a laser welding solution often lands on suppliers of beam sources or cutting machines, not on those who deliver a system ready for welding. The overview of German laser manufacturers maps out these segments, but the key for buyers is knowing which type of manufacturer supports welding in practice.
Only complete welding system manufacturers deliver the solution for the workshop
The German market divides into three segments: companies that make beam sources as components, those that build machines for laser cutting and marking, and those that develop and produce complete laser welding systems. For a workshop that needs to weld, only the third group matters. Sigma Laser is an example of a company in the third segment: since 2005, it has developed and built complete industrial laser welding systems in Hanau, Germany. The range includes six five-axis systems, both mobile and stationary, with either Nd:YAG or fibre laser sources. These systems are designed for flexible use in repair, toolmaking and production, without limits on part size or weight.
Four questions identify the manufacturer that fits production needs
A buyer can quickly identify the right partner by asking four questions: the origin of the system, the speed and method of service, the training offered, and the proof of welding capability.
- Where is the system developed and built?
- How fast does service respond, and how is a repair carried out?
- Who trains the operators?
- Does the manufacturer weld a sample on the customer’s material before the purchase?
Sigma Laser develops, produces and services its systems in one location. When contacted before 14:00, remote diagnosis via USB usually starts the same day. Most repairs are handled by exchanging modules on site, and maintenance is scheduled every 1,000 operating hours or at least every two years. Certified operator training is available, and the Sigomatic control allows a first weld programme to be set up without programming knowledge.
The weld on the customer’s material proves the manufacturer’s capability
In practice, the decisive step is a sample weld on the customer’s own material. This test shows seam appearance, penetration and the heat-affected zone. “We always weld a sample on the customer’s material before purchase and discuss the results in detail with the production team,” says Alexander Bellouzi, Senior Design & Engineering at Sigma Laser.
The Sineo system received the German Design Award 2025, and Sigma Laser systems are in use at more than 1,000 companies in over 25 countries, including reference customers such as Airbus, Siemens and Continental.
The most direct way to judge a manufacturer is a sample weld on your own material to evaluate seam quality and discuss the process with an experienced partner.
