Automatic Laser Welding System For Big WorkPieces
Simass Slide is an advanced automated welding platform designed for processing large and heavy workpieces with precision and speed. Featuring six CNC-controlled axes and three independent rotary slides, it enables high-volume production with minimal downtime — perfect for industries that demand maximum flexibility and throughput.
Introduction – What is Simass Slide?
The Simass Slide is a high-capacity automated laser welding platform developed to handle large and heavy workpieces such as oversized pipes and industrial components. Equipped with six numeric-controlled axes and three independent motorized slides, this system maximizes throughput by allowing parallel loading and unloading during the welding process — eliminating unnecessary downtimes and enhancing overall productivity.
Each of the three slides features motorized rotary axes with 315 mm chucks, supporting parts up to 500 mm in diameter and 1500 mm in length. The rotary axes are fully pivotable, enabling both horizontal and vertical welding operations with high flexibility.
Designed for demanding industrial applications, the Simass Slide supports the integration of high-efficiency fiber lasers in either continuous wave (cw) or pulsed mode, depending on the material and weld profile required.
The Simass Slide system delivers exceptional flexibility for laser welding operations involving oversized parts and long seams. Built with a focus on automation and heavy-load handling, it combines linear travel, motorized rotation, and multi-slide design to offer unparalleled efficiency.
Its six-axis configuration includes three individually movable slides, each with its own rotary chuck, allowing the operator to load and unload parts while welding is ongoing — significantly reducing cycle times. This architecture enables horizontal and vertical welding, with robust mechanical stability and repeatable precision.
Designed to integrate with fiber laser sources in both continuous wave and pulsed modes, Simass Slide is ideal for welding materials like steel, aluminum, and titanium in industrial-scale operations.

Ensuring Operator Safety with Every Weld – Guidelines for Using Simass Slide Responsibly
Operating the Simass Slide demands strict adherence to safety protocols due to its high-powered laser system, multi-axis motion capabilities, and the handling of large, heavy workpieces. The combination of motorized slides, rotational axes, and automated part loading during active welding introduces several potential hazards if proper safety measures are not observed.
This section outlines essential guidelines to ensure the safety of operators, maintenance personnel, and the surrounding environment. From laser radiation and mechanical movement to workpiece handling and emergency stops, each aspect has been carefully considered to provide a safe and efficient working environment.
Here’s how to ensure safe daily use of the Simass Slide system:
Laser Safety Classification
Simass Slide itself is non-emissive but is commonly used in Class 1 and Class 4 laser environments. The safety level of the overall welding setup depends on the connected laser head and whether safety enclosures or interlocks are in place.
- Recommended: Operate Simass Slide within a Class 1 certified laser enclosure for maximum protection.
- Minimum Requirement: If used in open (Class 4) configuration, ensure that line-of-sight laser exposure is strictly shielded at all times.
Personal Protective Equipment (PPE)
Due to the handling of large and potentially sharp or hot workpieces, and the possibility of exposure during setup or maintenance, proper PPE is essential.
Task |
Recommended PPE |
Routine operation |
No PPE required under closed housing |
Maintenance (open casing) |
Laser safety goggles (1064 nm rated) |
Welding setup adjustments |
Safety gloves, protective sleeves |
Handling heavy components |
Safety shoes, cut-resistant gloves |
Optical cleaning or inspection |
Anti-static gloves and lens-safe cloths |
Workspace Safety Requirements
Because the Simass Slide handles heavy and large-format parts (up to Ø500 mm × 1500 mm) and incorporates motorized multi-axis movement, extra attention must be paid to installation and access:
- Install on a level, vibration-free surface to maintain slide and axis stability.
- Maintain sufficient clearance around the entire system for safe movement of slides and easy operator access.
- Ensure ventilation is adequate to avoid overheating of the laser system and electronics.
- Do not stack materials near or behind the unit — unobstructed access to emergency stop buttons and power cutoff is essential.
- Define and label the Class 1 safety zone, and ensure only authorized personnel enter it.
- Place laser safety signage in clear view.
Electrical & Cooling System Safety
- Use a 3-phase 380V power supply, properly grounded.
- Only qualified personnel should access electrical cabinets or internal wiring.
- Use only Sigma-certified coolant fluids to prevent corrosion or malfunction.
- Regularly check coolant levels and inspect for leaks.
- Never operate the laser if coolant is low or the system displays temperature warnings.
- Keep power and signal cables secured and away from walkways or moving parts.
Software & Control Warnings
The Sigomatic interface used with Simass Slide provides live system status and fault alerts, including:
- Overheating
- Coolant level drop
- Laser or motor errors
- Interlock failures
⚠️ Never bypass safety interlocks or override system alarms.
Emergency Procedures
- An emergency stop button is located on the front control panel; pressing it halts all motion and laser activity instantly.
- A Class C fire extinguisher should be available for electrical or laser-related incidents.
- All operators should be briefed on shutdown and evacuation protocols.
- A power cutoff switch is located on the rear panel — it disconnects the full system from electricity.
In case of accidental exposure or mechanical incident, cease operation immediately and contact the safety supervisor.
Training & Access Control
- Only trained and authorized personnel should operate or maintain the Simass Slide.
- Access to advanced settings on the Sigomatic software should be restricted via user roles.
- Display clear safety signage around the machine and within the workspace.
