PDKJ Laser Welding Machine

Industry: Home Appliance & Kitchen Equipment Manufacturing

Workpiece: Oven Brackets

Recently, a 3000W Handheld Automatic Wire Feeding Fiber Laser Welding Machine supplied by PDKJ for a leading home appliance and kitchen equipment manufacturer in Foshan was successfully installed, commissioned, and officially put into production. The equipment has been operating steadily in the customer's workshop, providing reliable support for the welding of oven brackets.

I. Project Background

Customer Profile

The customer is a well-established manufacturer in the home appliance industry, specializing in the research, development, production, and sales of household and commercial kitchen appliances, baking equipment, and supporting sheet metal components.

With a standardized sheet metal production workshop, stable order volumes, and frequent product updates, the company maintains high industry standards for welding quality, product consistency, and mass-production efficiency.

Project Motivation

As a key structural component of ovens, the brackets are manufactured from 2mm galvanized steel sheets. Due to large production volumes and numerous welding points, the customer's existing welding process could no longer meet the requirements of production line upgrades.

After multiple rounds of sample testing, parameter optimization, and on-site welding comparisons, the customer ultimately selected the PDKJ laser welding solution.

II. Production Challenges and Core Requirements

With increasing demands for product quality and precision sheet metal fabrication, the high-precision and high-consistency welding of 2mm galvanized steel oven brackets placed greater requirements on the welding process. Traditional welding methods could no longer support the customer's production efficiency and quality improvement goals.

1. Frequent Welding Defects on Galvanized Steel

The melting point of the zinc coating is significantly lower than that of the steel substrate. During conventional welding, the zinc layer vaporizes rapidly under high temperatures, often causing:

• Porosity

• Slag inclusions

• Excessive spatter

• Incomplete fusion

As a result, the load-bearing weld strength of the brackets often failed to meet requirements, leading to a high defect rate.

2. Thin Sheet Deformation and Extensive Post-Processing

Traditional arc welding generates substantial heat input, causing:

• Thermal distortion

• Dimensional deviation

• Assembly difficulties

In addition, weld seams often appear dark and uneven, requiring extensive grinding and polishing. This increases production cycle times and labor costs.

3. Limited Flexibility for Product Variations

As product designs continue to evolve, various corner joints and lap joints must be welded.

Traditional fixture-based welding equipment lacks flexibility, resulting in:

• Long changeover times

• Reduced efficiency for small-batch production

• Limited flexible manufacturing capability

Customer Requirements

The customer required a solution capable of:

• Maintaining weld strength

• Improving welding consistency

• Reducing human-related quality variations

• Supporting stable mass production

III. Highlights of the PDKJ Laser Welding Solution

Based on the actual production conditions of the oven brackets, PDKJ optimized the welding parameters and equipped the system with an integrated automatic wire feeding unit, delivering a practical solution for mass production.

1. Precise Heat Control for Galvanized Thin Sheet Welding

The highly concentrated laser energy and minimal heat-affected zone effectively prevent:

• Burn-through

• Thermal deformation

The process also minimizes common galvanized steel welding defects such as:

• Porosity

• Spatter

• Cracking

As a result, weld fusion becomes more uniform, structural strength remains stable, and product qualification rates improve significantly.

2. Integrated Automatic Wire Feeding System

The integrated dual-drive wire feeding mechanism ensures smooth and uninterrupted wire delivery.

Advantages include:

• Better gap-bridging capability

• Stable filler wire welding for bracket joints

• No need to remove the galvanized coating beforehand

• Reduced pre-processing work

• Lower consumable costs

• Improved stability during long production runs

3. Superior Weld Appearance with Reduced Finishing Work

The laser-welded seams are:

• Smooth

• Uniform

• Free from excessive oxidation or discoloration

This significantly reduces grinding and polishing requirements, lowers labor and consumable costs, and decreases the overall manufacturing cost per part.

4. Easy Operation and Reduced Dependence on Skilled Welders

The system features preset parameter storage and an intuitive operating interface.

After approximately 30 minutes of training, ordinary operators can independently operate the machine without requiring highly skilled certified welders.

Benefits include:

• Reduced labor costs

• Easier workforce management

• Improved production flexibility

5. Industrial-Grade Stability for Continuous Production

The system is equipped with a 3000W fiber laser source designed for a service life exceeding 100,000 hours.

Combined with an independent water-cooling system, it provides:

• Stable temperature control

• Consistent laser output

• Reliable 24-hour continuous operation

The machine is also equipped with automation expansion interfaces, allowing future integration with robotic welding workstations and automated production lines.

IV. Project Results: Creating Value Through Stable Production

During the implementation phase, the PDKJ technical team provided comprehensive support, including:

• Equipment installation

• Parameter optimization

• Welding sample testing

• Operator training

This ensured seamless integration into the customer's existing production workflow.

Following successful pilot production verification, the machine was officially launched for continuous manufacturing.

On-Site Performance Results

• Stable equipment operation

• Weld seam quality meets production requirements

• Fully supports large-scale continuous processing

• Provides strong support for future mass production expansion

The successful deployment of the PDKJ laser welding solution has enabled the customer to improve welding quality, increase production efficiency, and establish a more reliable manufacturing process for oven bracket production.
