Rotational parts such as flanges, pulleys, gears, and housings often require consistent circumferential or ring welding. Traditional arc welding relies heavily on operator technique, which can lead to variations in heat input and defects such as porosity, spatter, and cracking. Single-station systems also require loading and unloading to stop during welding, increasing idle time and extending production cycles.

Han’s Laser’s Dual-Station Rotary Laser Welding Machine replaces conventional arc welding with laser welding and uses a rotating dual-station design to coordinate loading, clamping, welding, and unloading. While one station is welding, the other can be loaded or unloaded, creating a continuous production cycle for rotational components.

Dual-Station Rotary Design

The system uses two rotating workstations to keep loading and welding activities running in parallel.

While one station performs laser welding, the other station can complete manual loading and unloading. After welding, the workstations rotate and switch positions. This alternating operation reduces idle time caused by loading and unloading and helps maintain a consistent production rhythm.

The design is particularly suitable for batch production of rotational components where stable cycle times are important.

Automatic Clamping for Stable Welding

An automatic clamping mechanism applies up to 500 N of clamping force to secure the workpiece during welding. Once the part is positioned, the system automatically clamps it and releases the fixture after welding.

Stable workpiece positioning helps maintain consistent weld alignment and penetration across repeated parts while reducing manual clamping and handling operations.

Key Welding Benefits

• Stable penetration: Consistent laser energy helps maintain uniform weld depth across production batches.
• Clean weld seams: Controlled laser heat input can reduce spatter and improve weld appearance.
• Reduced post-processing: Cleaner welds can reduce grinding and rework requirements.
• Fume isolation: An enclosed welding area helps contain welding fumes and reduce their release into the surrounding workspace.

Safety and Defined Working Area

The system incorporates safety features for routine production operation, including a safety light curtain and dual-hand start buttons. Welding starts only after both hands simultaneously confirm the operation, helping reduce the risk of unintended activation.

The working range is up to 600 × 300 × 100 mm, covering a range of commonly processed rotational components. Manual loading and unloading are integrated with automatic laser welding, providing a balance between operator flexibility and automated processing.

Applications

The Dual-Station Rotary Laser Welding System can be used for a variety of rotational components and production environments.

Automotive Components

Suitable for circumferential and ring welding of flanges, pulleys, sensor housings, and other rotational automotive components.

Hardware and Machinery

Supports precision welding of gears, bearing sleeves, couplings, and similar mechanical components where consistent penetration and controlled heat input are required.

Appliances and Kitchenware

Applicable to rotational stainless-steel components such as cups, spouts, cookware components, and other parts where weld appearance and low spatter are important.

Production Line Integration

The rotary dual-station laser welder can be integrated into automated production lines. Manual loading and unloading can operate in parallel with automatic welding, supporting continuous and reduced-labor production.

A Practical Approach to Rotary Part Welding

By combining dual-station rotary operation, automatic clamping, and precision laser welding, the system addresses two common challenges in rotational-part production: inconsistent welding quality and production downtime during loading and unloading.

Its defined working range, safety functions, and flexible manual-loading configuration also make it suitable for standalone production or integration into automated manufacturing lines.
