Optical scanner galvanometer SUP 21 S/T e 23 S/T

High-precision oscillating galvanometer motor
Beam steering module for SUP laser welding heads 20S/T, 21T, 23S/T. The galvanometer motor is the core component enabling the wobble function in portable laser welding torches. It rapidly and precisely controls the mirror angle so the laser beam follows defined patterns (line, circle, figure-eight, etc.) to produce wider, stronger weld beads.

Technical features and performance

• Millimetric angular control: Designed for dynamic adjustment of the laser path. Allows real-time variation of weld width to optimize the molten pool even on imperfect joints.
• Long-term operational stability: Constructed from high thermal and mechanical resistance materials; tested for intensive duty cycles to ensure consistent performance without overheating or precision loss.
• High scanning speed: Supports elevated oscillation frequencies, essential to reduce spatter and achieve superior surface finish ("coin" effect or smooth bead).
• Plug-and-play integration: Engineered for rapid installation in the torch upper housing, with precise connectors for the SUP control board.

Benefits of the SUP galvanometer

• Laser path versatility: Accurate mirror control enables multiple welding modes, adapting to various materials (stainless steel, aluminum, carbon steel) and joint geometries.
• Industrial reliability: Sealed construction resists micro-vibrations typical of manual use, maintaining optical alignment between collimation and focusing optics.
• Intuitive adjustment: Fully compatible with the laser system software, allowing operators to set wobble width from 0 to 6 mm with ease.

Compatibility specifications

• Original/compatible spare part for SUP laser torches: models 20S, 20T, 21T, 23S, 23T.
• Compatible with SW systems: SW150 and 3-in-1 welding heads (Welding, Cutting, Cleaning).

Welding torch components (table)
Name | Function
Copper nozzle | Directs the laser beam and shielding gas to the weld point.
Graduated tube / adjustment ring | Allows millimetric focal position adjustment.
Protective lens | Shields internal optics from spatter and dust.
Focusing lens | Concentrates the laser into a very small, high-power spot.
Reflective lens / galvanometer | Directs the beam; in sway models it creates the oscillating movement.
Motor (Wobble) | Controls the beam oscillation for wider welds.
Collimation lens | Makes divergent fiber rays parallel.
Trigger / activation button | Controls laser emission (usually with contact safety).
Wire-feed bracket | Mechanical support for automatic filler wire insertion.
Water circuits / gas channel | Cool the torch (water) and protect the weld pool (gas).
Protective sleeve | Connector inlet and protection for the fiber optic connector.

Maintenance advice
The galvanometer motor is a precision component. During replacement ensure a dust-free environment and avoid excessive bending of signal cables to prevent mirror movement interference.
