Handheld + Automated Laser Welding, Cutting & Cleaning: One Machine for Flexible Processing

Introduction

Many metal fabrication and repair applications require different levels of processing flexibility. A component may need manual welding for a quick repair, programmed welding for repeatable production, local cutting for trimming, or laser cleaning for surface preparation.

Traditionally, these tasks may require separate equipment or repeated workpiece transfers. Moving a part between machines increases handling time, requires additional fixturing, and can introduce repositioning errors.

Han’s Laser developed a dedicated handheld + automated laser welding, cutting, and cleaning machine to address these challenges. The system combines three laser processing functions with a unique dual-mode welding configuration.

The welding gun can be used as a flexible handheld tool or secured to the workstation for automated motion. This allows one machine to support everything from on-site repair and rapid prototyping to repeatable small-batch production.

Handheld + Automated: Two Modes in One Machine

The core value of the workstation is its ability to switch between handheld and automated operation.

A dedicated locking and positioning mechanism securely mounts the handheld welding gun to the machine. Once mounted, the welding gun becomes an automated processing unit that works with the workstation’s motion axes.

Handheld Mode for Flexible Repair and Prototyping

The welding gun can be quickly removed from the workstation when manual operation is more practical.

Handheld operation is suitable for:

On-site or localized repair
Irregularly shaped components
Quick sample development
One-off welding jobs
Workpieces that are difficult to fixture
Flexible repair and maintenance tasks

This mode preserves the mobility and accessibility of a handheld laser welder without requiring a dedicated automated welding cell.

Automated Mode for Repeatable Processing

When the welding gun is secured to the workstation, programmed machine movement can be used for repeatable welding operations.

Automated operation is particularly useful for:

Small-batch production
Repetitive components
Process validation
Sample-to-sample consistency
Standardized repair operations
Welding parameter development

The same machine can therefore move from manual intervention to programmed processing as production requirements change.

Why Dual-Mode Processing Matters

Different manufacturing stages require different levels of automation.

During product development, operators may need to quickly adjust a workpiece or experiment with different welding positions. During small-batch production, however, repeatable motion and consistent process parameters become more important.

A fixed automated system may be too restrictive for occasional repair work, while a fully handheld process can make repetitive production dependent on operator technique.

The dual-mode configuration provides a practical middle ground:

Handheld operation → repair and flexibility

Automated operation → repeatability and batch processing

This allows manufacturers to use the same equipment across different production requirements instead of dedicating separate equipment to each application.

Three Laser Processes in One Workstation

In addition to dual-mode welding, the workstation integrates laser welding, local laser cutting, and laser cleaning.

This process integration reduces the need to transfer workpieces between multiple machines.

Typical applications include:

Welding and repair
Local cutting and trimming
Surface cleaning and refurbishment
Defect removal and repair preparation
Mold restoration
Prototype processing

Combining these functions can reduce equipment investment and floor-space requirements while simplifying material handling.

500 × 500 × 150 mm Three-Axis Working Range

The workstation features a three-axis motion system with:

X-axis travel: 500 mm
Y-axis travel: 500 mm
Z-axis travel: 150 mm

The large working range provides processing coverage for medium-sized molds, metal components, and irregular workpieces.

For automated welding, the three-axis system provides controlled movement around the workpiece. For repair applications, it can reduce the need for repeated repositioning when multiple areas of a component require processing.

Adjustable Welding Orientation for Complex Parts

Complex components often include deep cavities, internal walls, corners, inclined surfaces, and curved sections.

The workstation incorporates an adjustable rotary table that allows the welding position to be changed according to the geometry of the workpiece.

This provides additional flexibility for:

Deep-cavity mold repair
Internal wall welding
Corner and edge repair
Inclined surfaces
Curved components
Irregular metal structures

Instead of repeatedly disassembling and turning a workpiece, operators can adjust its orientation to create a more suitable welding position.

A Practical Solution for Mold Repair

Mold repair is one of the applications that benefits strongly from the dual-mode configuration.

For a one-off repair or difficult-to-access area, the welding gun can be removed and used manually. When repetitive repair operations or standardized processing are required, the gun can be mounted to the workstation for programmed movement.

The three-axis working range and adjustable rotary table further support repair of:

Deep cavities
Corners
Inclined surfaces
Localized defects
Complex mold surfaces

This combination allows the same machine to support both flexible repair work and more repeatable repair processes.

Supporting New Product Development and Prototyping

Product development often involves frequent design changes and multiple sample iterations.

Handheld operation provides the flexibility needed for quick welding tests and early-stage sample development. Once a suitable process has been established, the welding gun can be fixed to the workstation to reproduce the motion and welding parameters.

This makes the machine suitable for:

New product samples
Welding process verification
Prototype iteration
Parameter development
Small-scale process validation

The transition from manual testing to automated processing can also help manufacturers establish more repeatable welding procedures before moving into larger-scale production.

Small-Batch Automated Welding

Not every manufacturer needs a dedicated automated production line.

For small and medium production volumes, the dual-mode workstation provides a more flexible alternative. Operators can use handheld mode for low-volume or customized work and switch to automated mode when the same components need to be processed repeatedly.

Once the welding gun is secured, the machine’s motion system can execute programmed welding paths, reducing reliance on individual operator technique.

This can help improve process consistency while making better use of the equipment across different production tasks.

Applications Beyond Welding

Laser Cutting

The integrated cutting function can be used for localized cutting, trimming, and shape correction.

This is useful when cutting is required as part of a repair or fabrication operation without transferring the workpiece to another laser cutting machine.

Laser Cleaning

Laser cleaning can support surface preparation, refurbishment, and removal of unwanted surface contaminants before or after processing.

Having cleaning capability within the same workstation can simplify operations that otherwise require an additional piece of equipment.

Hardware and Irregular Components

The system can process various metal components, including stainless steel and carbon steel parts, valves, tubes, and other irregular structures.

The adjustable workpiece orientation is particularly useful for curved and inclined surfaces.

Stable Mechanical Structure and Fiber Protection

For automated operation, mechanical stability is important for consistent positioning.

The workstation uses an integrated elevated structural support and dedicated workholding base to provide a rigid processing foundation. The structure helps suppress vibration and deformation during machine movement.

A dedicated fiber support system is also provided to guide and protect the laser fiber during operation. This helps reduce excessive pulling and bending that could otherwise affect the optical path and fiber service life.

Suitable for Research, Training, and Technical Development

The dual-mode design also expands the workstation’s value beyond production.

Universities, research institutes, and technical training centers can use handheld mode for practical welding instruction while using automated mode for process experiments and repeatability studies.

One machine can therefore support:

Hands-on welding training
Automated process experiments
Welding parameter research
Prototype development
Process demonstrations

This makes the workstation suitable for environments where both manual skills and automated laser processing need to be evaluated.

One Machine for Different Production Needs

The key advantage of this workstation is not simply the combination of three laser processes. Its greater value comes from the ability to change between handheld and automated operation according to the task.

A typical usage pattern may look like:

Repair → Handheld Mode

Prototype Development → Handheld + Automated Mode

Process Validation → Automated Mode

Small-Batch Production → Automated Mode

Complex or Irregular Work → Handheld Mode

This flexibility allows manufacturers to adapt the same equipment to changing production requirements without maintaining separate machines for every task.

Conclusion

The Handheld + Automated Laser Welding, Cutting & Cleaning Machine from Han’s Laser is designed for manufacturers that need flexibility across repair, prototyping, processing, and small-batch production.

By combining handheld mobility with automated machine movement, the workstation can support both customized work and repeatable processing. Its integrated welding, cutting, and cleaning functions further reduce the need for multiple standalone machines.

With a 500 × 500 × 150 mm three-axis working range, adjustable welding orientation, rigid mechanical structure, and protected laser fiber routing, the system provides a practical approach to flexible laser processing.

For manufacturers looking to bridge the gap between handheld repair and automated production, a dual-mode laser workstation can provide greater equipment utilization while supporting a wider range of applications.
