▷ Application Industry: New Energy Industry ▷ Welding Workpieces: Battery Enclosures / High-Voltage Control Cabinets
As the energy storage and new energy industries continue to expand, many manufacturers are accelerating the construction of new production facilities and doubling their capacity. Improving the quality and efficiency of enclosure welding has become one of the most critical challenges during factory expansion and production ramp-up.
Recently, PDKJ successfully completed the delivery and commissioning of a complete welding equipment solution for a customer in the new energy sector. The project included air-cooled handheld laser welding machines and robotic laser welding workstations, which have now been officially put into production.
Designed specifically for the large-scale welding of2mm carbon steel battery enclosures and high-voltage control cabinets, this integrated automated welding solution helps the customer achieve efficient production startup and capacity expansion in its new manufacturing facility.
Ⅰ Project Background
Customer Overview
The customer specializes in the energy storage industry and focuses on the development and production of:
Energy storage battery enclosures
High-voltage electrical control cabinets
Structural components for energy storage equipment
Their products are widely used in:
Commercial and industrial energy storage systems
New energy power systems
Outdoor energy storage equipment
The primary workpiece for this project is a 2mm carbon steel enclosure structure.
Project Motivation
Driven by the rapid growth of the energy storage market, the customer experienced a significant increase in order volume.
To expand production capacity and meet growing market demand, the company launched a factory expansion project and established a new standardized production facility.
Ⅱ Customer Challenges and Core Requirements
The new factory focuses on the mass production of 2mm carbon steel battery boxes and high-voltage cabinets.
Previously, the customer relied on traditional welding processes such as:
TIG welding
CO₂ gas shielded welding
However, these methods exposed several production bottlenecks during large-scale manufacturing.
1. Thin Sheet Welding Caused Deformation and High Scrap Rates
At only 2mm thick, carbon steel sheets are highly sensitive to heat input.
Traditional welding methods generate:
Excessive heat input
Large heat-affected zones
As a result:
Enclosure frames easily warp and deform
Burn-through frequently occurs
Weld cracking becomes common
These issues lead to:
High defect rates
Extensive rework
Increased material waste
Higher production costs
2. Poor Process Consistency and Difficult Quality Control
This makes it difficult to meet the strict sealing and structural strength requirements demanded by new energy battery enclosures and high-voltage cabinets.
Customer Requirement
The customer needed a welding solution capable of supporting:
Large-scale production
Standardized manufacturing
High-quality enclosure fabrication
for its new factory operations.
Ⅲ PDKJ Integrated Welding Solution
To address the customer's mass-production requirements, PDKJ developed a comprehensive welding solution consisting of:
Air-Cooled Handheld Laser Welding Machines
Robot Laser Welding Workstations
This dual-equipment configuration combines:
Production flexibility
High automation efficiency
Standardized batch manufacturing
effectively solving the limitations of traditional welding processes while supporting the customer's capacity expansion goals.
1、Precise Heat Control Minimizes Workpiece Damage
PDKJ laser welding equipment delivers highly concentrated energy with a very small heat-affected zone.
For 2mm carbon steel welding, this provides excellent performance by significantly reducing:
making it ideal for precision welding applications in the new energy industry.
2、Superior Weld Quality Simplifies Production Processes
Laser welding produces:
Smooth weld seams
Uniform weld appearance
Minimal spatter
Because of the high-quality weld finish:
Extensive grinding is no longer required
Only minor touch-up work is needed
This streamlines the manufacturing process and improves overall production efficiency.
3、Easy Operation Reduces Dependence on Skilled Welders
The system features an intelligent welding process platform with built-in welding parameter libraries specifically optimized for carbon steel enclosures.
Benefits include:
Simple operation
Short training periods
Reduced reliance on highly experienced welders
Even operators with limited welding experience can quickly become productive, significantly lowering labor costs and recruitment challenges.
4、Human-Robot Collaboration Supports High-Volume Production
The robotic welding workstation is designed for:
Continuous automated production
Stable welding trajectories
High precision welding
It can operate continuously around the clock, ensuring excellent consistency across large production batches.
Meanwhile, the portable air-cooled handheld laser welder provides:
Flexible deployment
Rapid setup
Convenient support for auxiliary welding operations
Together, the two systems maximize production capacity and fully support the customer's expanded manufacturing requirements.
5、Highly Versatile for Multiple Enclosure Types
The complete welding solution is suitable for a wide range of:
Battery enclosure models
High-voltage electrical cabinets
Advantages include:
Fast product changeovers
Easy parameter adjustments
Flexible production planning
allowing the customer to efficiently manufacture multiple product types on the same production line.
Ⅳ Project Results: Stable Production Creates Value
After full implementation, the customer's new energy enclosure production facility achieved significant operational improvements.
✅ Quality Improvement
Weld consistency improved substantially across production batches
Products fully meet sealing and structural strength inspection standards
Welding defect rates were dramatically reduced
✅ Cost Reduction and Efficiency Enhancement
Grinding operations were significantly reduced
Labor requirements decreased
Material waste and scrap losses dropped substantially
Per-unit manufacturing costs were lowered
At the same time:
Automated production capacity increased significantly
New orders resulting from factory expansion can now be easily accommodated
✅ More Stable Production Operations
The company no longer depends heavily on highly skilled welders.
Production performance is now less affected by:
Employee turnover
Skill level variations
Workforce shortages
As a result:
Production stability improved significantly
Manufacturing continuity increased
Long-term operational reliability was strengthened
Through the successful deployment of PDKJ's air-cooled handheld laser welding machines and robotic laser welding workstations, the customer achieved a highly efficient, scalable, and standardized welding solution that supports the growing demands of the new energy industry while delivering improved product quality, lower costs, and enhanced production capacity.
