When a vehicle surges up a steep slope or rattles over deep potholes, the unsung hero absorbing the shock and stress is the non-load-bearing vehicle body frame—the “backbone” of durability and torsional resistance. However, traditional arc welding methods struggle to meet the demands of modern vehicle frame assembly. Challenges include deformation from excessive heat during arc welding, failure to penetrate mixed-material weld seams, and equipment overheating on non-stop production lines.
To overcome these obstacles, Han’s Laser has developed the WSH07T-CW handheld water-cooled dual wire laser welding system, purpose-built to tackle the industrial challenges of “backbone-level welding” for non-load-bearing body structures.
Vehicle Body Frame
Key Features & Advantages
1.Water-Cooled Thermal Shield: Continuous Operation, Consistent Precision
At the heart of the WSH07T-CW is Han’s Laser’s proprietary closed-loop water cooling system, creating a stable thermal environment—even during 24/7 full-capacity production.
- For thick steel beams: Deep, uniform welds without collapse or warping.
- For thin-walled aluminum parts: Sharply reduced heat-affected zones, minimizing burn-through and distortion.
From main longitudinal beams to subframe brackets, the weld seams withstand extreme real-world forces—off-road jolts, heavy loads, and everything in between.
2.Dual-Wire Intelligent Feeder: One System, Multiple Material Solutions
This dual-wire feeding module works like a smart ammunition system for the laser welder:
- Thick structural steel: Larger wire feeds for deep, high-efficiency welds.
- Lightweight aluminum attachments: Finer wire ensures precise edges without over-penetration.
Whether you’re welding steel, aluminum, or mixed-metal configurations, this system handles multi-thickness, multi-material joining with a single setup, greatly expanding production flexibility.
3.Smart Integration for Production Lines: Automated, Scalable, Efficient
Leveraging Han’s Laser’s full-stack expertise in laser + automation integration, the WSH07T-CW can be seamlessly embedded into smart production cells.
Collaborative robots, positioning tables, and rotary axes enable full-process automation.
Real-time monitoring and system coordination boost output while reducing human error.
The result? A significant leap in both efficiency and consistency.
Applications Across Industries
The versatility and robust design of the handheld water-cooled dual wire laser welding system make it an ideal solution across multiple demanding industries:
Kitchen & Home Appliances
Precision welding of stainless steel frames, metal housings, and internal components ensures durable, leak-proof, and aesthetically flawless products like gas stoves, range hoods, and water heaters.
Hardware & Machinery
High-strength welds on structural components and moving parts improve the reliability and lifespan of industrial machinery, hand tools, and hardware fittings, even under heavy load or repetitive use.
Automotive Manufacturing
From non-load-bearing body frames to mixed-material lightweight parts, the system addresses challenges of welding high-strength steel and aluminum alloys, meeting strict safety, durability, and efficiency standards.
Elevator Industry
Critical safety components such as elevator cabins, door frames, and load-bearing structures require consistent, high-quality welds to guarantee performance and passenger safety under demanding conditions.
By delivering superior weld quality, stable operation, and flexible material handling, the WSH07T-CW supports manufacturers in these sectors to boost production efficiency, reduce defects, and enhance product reliability.
Looking Ahead: Built to Withstand, Engineered to Excel
From rugged terrain to hauling heavy loads, the weld seams of non-load-bearing frames face relentless stress. With the WSH07T-CW, Han’s Laser delivers a breakthrough:
- “Thermal Shield” for precision under pressure
