PDKJ Laser Welding Machine

▷ Industry: New Energy Storage Industry
▷ Welding Application: Aluminum Battery Base Plates & Battery Enclosures

In recent years, with the rapid growth of the new energy vehicle (NEV) and energy storage industries, the demand for manufacturing aluminum alloy battery enclosures, battery base plates, and battery trays has continued to increase. As a critical manufacturing process, welding directly affects product strength, sealing performance, production efficiency, and manufacturing costs.

Recently, a PDKJ Air-Cooled Handheld Laser Welding Machine was successfully installed, commissioned, and officially delivered to a local customer's production facility, providing stable and efficient welding support for the manufacturing of new energy products.

Ⅰ Project Background

Customer Profile

The customer specializes in the R&D and manufacturing of structural battery components and thermal management parts for the new energy industry. Their products are widely used in:

• New Energy Vehicles (NEVs)

• Energy Storage Systems

• Battery Pack Manufacturing

The purchased laser welding machine is primarily used for:

• Aluminum alloy battery base plate welding

• Aluminum battery tray welding

• Battery enclosure structural welding

• Aluminum sheet metal component assembly

As customer orders continued to increase, they required higher welding efficiency while maintaining consistent weld quality for mass production.

Ⅱ Customer Challenges

During production, the customer identified several key requirements.

1. Stable Aluminum Welding Quality

Aluminum features high thermal conductivity and high laser reflectivity. Traditional welding methods often result in inconsistent weld formation, excessive deformation, and unstable weld quality.

A more stable welding process was needed.

2. Higher Production Efficiency

With increasing production volume, the customer wanted to shorten welding cycle times and improve overall productivity.

3. Greater Operational Flexibility

Since multiple product sizes are manufactured, welding positions change frequently.

The customer required equipment that could easily adapt to different workpieces while minimizing fixture adjustment time.

4. Reduced Post-processing

High-quality weld seams would reduce grinding and finishing operations, further improving manufacturing efficiency.

Ⅲ PDKJ Laser Welding Solution

Based on the customer's products and production requirements, PDKJ supplied a 2000W Air-Cooled Handheld Fiber Laser Welding Machine.

Compared with conventional welding methods, the machine offers several significant advantages.

1. Fully Air-Cooled Integrated Design for Maximum Mobility

The machine features an integrated high-efficiency air-cooling system.

No external water chiller, coolant, or antifreeze is required.

It operates directly from a standard 220V industrial power outlet, allowing production to begin within just five minutes.

Its lightweight design enables a single operator to easily move the machine between different workstations, making it ideal for:

• Battery trays

• Battery enclosures

• Narrow internal weld seams

• Shared multi-station production

2. Flexible Handheld Welding Gun for Complex Welds

The ergonomic handheld welding gun allows operators to weld:

• Battery tray corners

• Interior enclosure joints

• Curved aluminum structures

• Complex sheet metal assemblies

without repeatedly repositioning large workpieces or designing complicated fixtures.

Compared with conventional TIG welding, welding speed can increase by 2–3 times.

The machine can also complement friction stir welding production lines by performing localized repair welding and welding irregular edge joints.

3. Intelligent Welding Parameter Library

The touchscreen controller includes optimized welding parameters for:

• Aluminum Alloy

• Stainless Steel

• Carbon Steel

• Galvanized Steel

Operators can simply select the required material without repeatedly adjusting welding parameters.

After only a short training period, ordinary workers can independently operate the machine, reducing dependence on experienced TIG welders and lowering labor costs.

4. One Machine for Multiple Materials

The machine can weld:

• Aluminum battery trays

• Energy storage enclosures

• Stainless steel cabinets

• Carbon steel furniture frames

This versatility allows manufacturers to efficiently handle multiple product types and small-batch production while improving equipment utilization.

The machine also incorporates multiple laser safety protection systems and supports continuous 8-hour industrial production with excellent reliability and minimal downtime.

Ⅳ Production Results

The PDKJ 2000W Air-Cooled Handheld Laser Welding Machine has now been fully installed and is operating reliably in the customer's factory.

For aluminum battery trays, heat sinks, and liquid cooling plate manufacturing, the equipment has delivered measurable improvements:

✅ Reduced grinding and finishing operations, lowering labor and consumable costs.

✅ Portable equipment shared across multiple workstations, improving factory space utilization without adding dedicated welding stations.

✅ Simple operation allows new employees to become productive quickly, reducing dependence on skilled welders and lowering labor costs.

✅ One machine supports both new energy aluminum components and general sheet metal fabrication, increasing equipment utilization while providing greater production flexibility.

PDKJ specializes in the research, development, and manufacturing of handheld laser welding machines.

Our air-cooled and water-cooled product range covers power levels from 1200W to 3000W, with all machines certified to CE standards.
