Robot Laser Welding Machine

▷ Application Industry: Hardware & Sheet Metal Manufacturing
▷ Welding Workpiece: Galvanized Sheet Metal Cold Plates

Recently, the PDKJ Robot Laser Welding System successfully completed delivery and commissioning and was installed at the production facility of a hardware manufacturing company in Shenzhen. The system has officially been put into automated mass production of cold plates.

Supported by mature and stable laser welding processes and a robotic automation solution, the system effectively addresses the customer's welding challenges in mass production while helping improve production quality and efficiency.

I. Project Background

Customer Profile

The customer has extensive experience in the hardware manufacturing industry and specializes in sheet metal component processing. The company also manufactures cold plate products for downstream applications, where strict requirements are placed on welding quality and finished product performance.

Project Background

As customer orders continued to increase, the company needed to improve production efficiency while maintaining consistent product quality. After comparing and evaluating multiple solutions, the customer selected a customized PDKJ robot laser welding solution to upgrade its welding production line.

II. Customer Production Challenges and Key Requirements

The customer mainly faced three production requirements:

1. Welding Efficiency Needed Improvement

The products were manufactured in batches, and manual welding involved a high level of repetitive work. The customer wanted to improve overall welding efficiency.

2. High Welding Quality Requirements

For laser welding of galvanized sheet metal, welding defects such as porosity needed to be carefully controlled.

3. Product Airtightness Requirements

The cold plates require complete and reliable weld seams. After welding, the products must meet the corresponding airtightness requirements.

Therefore, the customer's core requirements were clear:

Improve welding efficiency, reduce welding porosity, ensure consistent welding quality, and meet product airtightness requirements.

III. Key Features of the PDKJ Solution

Based on the customer's products, material characteristics, and production requirements, PDKJ configured a 1500W six-axis robot laser welding solution.

The system is primarily used for welding 2.0 mm galvanized sheet metal cold plates, with the robot performing repetitive welding operations according to programmed welding paths.

Compared with relying entirely on manual repetitive welding, robotic welding reduces repetitive manual operations and provides more consistent welding paths and production cycles, making it particularly suitable for products requiring high-volume production.

1. Optimized Welding Process to Reduce Porosity

PDKJ optimized the laser welding parameters specifically for galvanized sheet metal and precisely controlled heat input to effectively manage the vaporization of the galvanized coating.

This helps produce dense and smooth weld seams while reducing defects such as porosity and incomplete fusion, helping the finished products meet airtightness inspection requirements.

2. Automated Robotic Welding for Consistent Quality

The KUKA six-axis robotic arm provides precise and programmable movement with high repeatability.

The entire welding process is automated, reducing errors associated with manual operation. During mass production, the welding seams remain consistent, helping improve product yield and overall welding quality.

3. Efficient Mass Production to Overcome Capacity Constraints

The system supports stable continuous operation, reducing the need for frequent manual intervention.

The automated welding process significantly improves welding efficiency and is well suited to the customer's high-volume and continuous production requirements.

4. One-Stop Implementation Service for Faster Production

PDKJ provides comprehensive project support, including:

• Initial welding sample testing

• Customized solution design

• Equipment delivery

• On-site installation and commissioning

This integrated service helps shorten the customer's preparation period and enables the equipment to enter production and generate value more quickly.

IV. Delivery Results: Stable Production Creates Value

The delivered robot laser welding workstation has now been installed in the customer's production workshop. All commissioning and process adaptation work has been completed, and the system has officially been integrated into the production line for regular mass production.

The equipment is operating stably, and the robot welding workstation is precisely matched with the customer's production fixtures.

Workshop operators have completed training and are now operating the system as part of their regular production activities. Welding quality continues to meet the required standards, effectively addressing the customer's cold plate welding challenges.
