Swivel Optics in Laser Welding Equipment

Swivel optics are a specialized optical beam delivery component used in advanced laser welding systems. These optics enable angular beam adjustment and multi-directional flexibility, allowing the laser beam to be tilted, rotated, or swiveled relative to the work surface. This function is especially useful for complex geometries, hard-to-reach welding zones, and curved or angled joints.

In systems like those developed by Sigma Laser, swivel optics enhance both manual and semi-automated welding tasks by increasing accessibility and precision without repositioning the entire workpiece or machine.

Overview

Swivel optics are typically mounted at the end of the laser beam delivery path and include a motorized or manually adjustable lens head that can:

• Rotate ±360° horizontally
• Tilt ±90° vertically
• Be fixed at custom angles for repeatable weld paths

This adds a rotational degree of freedom to the beam, giving operators ergonomic and technical advantages when working on parts with varying orientations.

Applications

Swivel optics are ideal for:

• Tool & mold repair (e.g., internal corners or undercuts)
• Dental and medical devices (micro-welding curved surfaces)

• Ensure secure locking of the swivel head during welding.
• Regularly inspect joints and moving components for wear or misalignment.
• Clean optical windows to prevent distortion of angled beams.

Safety Considerations

• Eye protection remains critical due to changes in beam direction.
• Mechanical locks should be used to prevent unintentional swivel during operation.
• Ensure beam paths remain within Class 1 enclosure or guarded space.

Integration with CNC & Manual Welding

Swivel optics can be used in both:

• Manual workstations (operator-controlled angle changes during welding)
• CNC laser systems (pre-programmed multi-angle beam orientation for complex weld paths)

In CNC systems, the swivel movement can be synchronized with other axes to perform 3D welds on curved or irregular surfaces.
