PDKJ Laser Welding Machine

▷ Industry: HVAC Industry
▷ Welded Workpiece: Air Conditioner Cabinets

Recently, Guangdong Pudian Automation Technology Co., Ltd. added another successful overseas benchmark project to its portfolio. Our 3000W Swing Arm Laser Welding Machine was successfully delivered to a leading air conditioning manufacturer in the Middle East, where it completed installation and commissioning and has now been officially put into mass production.

The equipment is specifically designed for laser spot welding of 1.0–3.0 mm galvanized steel reinforcement ribs, helping large HVAC manufacturers upgrade their welding processes through stable production performance and mature international project support services.

Ⅰ Project Background

Customer Profile

The customer is one of the leading HVAC system manufacturers in the Middle East, with more than 50 years of industry experience. The company operates standardized production facilities with an annual production capacity exceeding one million units.

Its product portfolio includes:

• Residential split air conditioners

• Window air conditioners

• Central air conditioning systems

• Industrial air handling units (AHUs)

Supported by advanced testing laboratories and a comprehensive service network, the company's products are widely used in commercial buildings, industrial parks, public facilities, and infrastructure projects, with extensive exports worldwide.

Project Motivation

The customer uses galvanized steel sheets extensively in the manufacturing of air-conditioner cabinets. Spot welding of cabinet reinforcement ribs is a critical production process that directly affects structural strength and product appearance.

As production capacity continued to expand and quality requirements became increasingly stringent, the customer sought to optimize its cabinet welding process, improve manufacturing efficiency, and enhance product consistency to support future large-scale production.

Ⅱ Production Challenges and Customer Requirements

Before introducing the PDKJ laser welding solution, the customer relied on conventional welding methods for galvanized reinforcement rib welding. Over time, the limitations of traditional welding processes became increasingly evident and began restricting productivity and product quality.

1. High Defect Rate

Galvanized steel welding often resulted in:

• Zinc coating peeling

• Excessive spatter

• Weak or incomplete welds

These defects increased rework costs and made it difficult to meet strict export quality standards.

2. Sheet Metal Deformation

Traditional welding methods generate significant heat input, causing thin galvanized sheets to warp and deform.

As a result:

• Additional grinding and correction processes were required

• Production cycles became longer

• Manufacturing efficiency decreased

3. Heavy Dependence on Skilled Labor

Conventional welding requires experienced welders to maintain quality.

Challenges included:

• High overseas labor costs

• Difficult recruitment of skilled welders

• Inconsistent welding quality during mass production

Customer Requirements

The customer required a welding solution capable of delivering:

• Excellent compatibility with galvanized steel

• Minimal deformation

• Low material consumption

• Easy operation

• Long-term continuous production capability

while meeting international mass-production standards.

Ⅲ Highlights of the PDKJ Laser Welding Solution

For the customer's galvanized air-conditioner cabinet welding application, the PDKJ engineering team conducted extensive process analysis and welding sample tests.

After multiple rounds of validation, a 3000W Platform-Type Seamless Laser Welding Machine was selected and configured for the project.

1. Seamless Welding for Better Appearance

The machine utilizes advanced laser spot welding technology.

Benefits include:

• Highly concentrated heat input

• Uniform weld formation

• Reduced surface indentation

• Improved product appearance

• Fewer visible welding marks compared with traditional methods

2. Stronger Welds with Higher Consistency

For welding reinforcement ribs made from 1.0–3.0 mm galvanized steel sheets, the equipment provides stable and repeatable weld quality.

Advantages include:

• Consistent weld positioning

• Reliable weld strength

• Improved cabinet structural integrity

3. Flexible and Efficient Operation

The swing-arm structure offers excellent maneuverability.

Benefits include:

• No need to frequently reposition large workpieces

• Ideal for large cabinet sheet-metal assemblies

• Increased production efficiency

4. Platform Design for Mass Production

The platform structure enables:

• Easy workpiece positioning

• High repeatability

• Consistent processing quality

making it highly suitable for large-scale cabinet manufacturing.

5. Repeatable Process Parameters

The system supports welding parameter storage and recall.

This allows operators to:

• Quickly switch between different product specifications

• Reduce setup time

• Improve production management efficiency

• Maintain product consistency

Ⅳ Partnership Invitation: Upgrade Your Welding Production with PDKJ
