Stationary Laser Welding Systems for Industrial Manufacturing
A stationary laser welding machine is a fixed, CNC-controlled laser welding system for repeatable production and repair of metal components. At Sigma Laser, a 5-axis kinematic system (X·Y·Z·C·D) guides the beam over the workpiece; the open-frame design accommodates components of any size and weight, while stored programmes ensure consistent seams in series production.
Increase your process reliability and efficiency with stationary laser welding machines from Sigma Laser.
Stationary laser welding machines provide high process stability and are designed for the requirements of industrial series production. They deliver precise results with a wide range of component sizes and geometries.
Repeatability in series production
With storage for up to 100 welding programmes and CNC-controlled 5-axis kinematics, recurring welding tasks can be performed accurately and efficiently. This ensures consistent quality and reduces rework.
Open-frame design and component flexibility
The open-frame design allows processing of workpieces of any size and weight. Component heights up to 450 mm are possible—independent of table size. Large or heavy parts can be welded without difficulty.
Automatable with Simass modules
By integrating Simass systems, the degree of automation can be flexibly adjusted. Modules such as rotary table or slide enable efficient series production and parallel loading and unloading during the welding process.

The choice between a stationary laser welding machine and a mobile laser welding machine depends on your production requirements. The following criteria can support your decision-making process.
Stationary laser welding systems are suitable when components can reliably be brought to the machine. For very large or permanently installed parts, a mobile solution is recommended.
For high batch sizes and short cycle times, stationary laser welding machines offer clear advantages through automation and repeatable processes.
Stationary laser welding systems can be flexibly automated using modules such as Simass. Mobile laser welding machines are typically designed for manual or semi-automated applications.
Stationary laser welding machines are permanently integrated into the production line and provide stable process conditions. Mobile systems are advantageous for changing workstations or limited space.
Mobile laser welding machines are developed for flexible use at different locations. Stationary laser welding systems are intended for continuous operation at a fixed site.
For flexible applications directly on the workpiece, the mobile laser welding machines Sineo Light, Sineo Fibre and Sirius Light are available – the laser welding buying guide explains the criteria in detail.

A stationary laser welding machine is a fixed industrial laser welding system designed for precise joining and repair of metal components. It features CNC-controlled axes, a permanent installation site, and is suitable for repeatable welding processes on small to large workpieces of various geometries.
The cost of a laser welding machine depends on the beam source, laser power, axis configuration, level of automation, custom features, and training requirements. After a personal consultation, you will receive a tailored offer that takes all relevant factors into account.
For series production, stationary laser welding machines such as Sidanus Light, Sidanus Fibre or Siega Fibre with programme memory for repeatable operations are suitable. For automated high-throughput production, the modular Simass system with flexible extensions is particularly well suited.
A stationary laser welding system offers advantages for recurring welding tasks, complex geometries, and automation. Mobile machines are ideal for repairs directly at the site or for large, difficult-to-move workpieces. The choice depends on part size, flexibility, and process requirements.
Stationary laser welding systems such as the Simass system can be automated through modular extensions. The base unit can be combined with Rotate, Slide or Powder modules. Modules are interchangeable and allow flexible adaptation to changing production tasks.
The open-frame design of Sigma Laser systems means there are no limits on workpiece size or weight; only the part height is restricted to 450 mm. With Simass Slide, components up to Ø 500 mm and 1,500 mm in length can be processed. The choice depends on your specific application.
