Xinxiang Automotive Radiator Factory, a medium-sized automotive parts manufacturer, specializes in producing automotive radiators. One of their key challenges was welding the aluminum alloy heat fins to the carbon steel frame, a process that involved dissimilar materials. Traditional TIG welding often led to issues such as weak welds and water leakage, resulting in a 12% rework rate. Additionally, their automated production line, running 8-hour shifts, faced unstable weld quality due to fluctuating welding gun temperatures. The company needed 1500 W Laser Welding Machine solution to meet their production demands.
Custom Requirements
Xinxiang Automotive Radiator Factory requires a welding solution with the following specifications:
- Capable of efficiently welding dissimilar materials such as aluminum alloy and carbon steel, addressing weld strength and leakage issues.
- Ensures stable welding performance during continuous 8-hour operations on automated production lines.
- Reduces rework rates and maintains consistent weld quality to enhance production efficiency.
- Increases overall production capacity while lowering material costs.
Solution
Kempson Team recommends the portable water cooling 1500 W laser welding machine for thin plates, model KPS-LHW1500. This 1500W machine delivers optimal performance for welding dissimilar materials: 2mm aluminum alloy fillet welds and 3mm carbon steel joints. It features a Tewell 4.2kW full copper tube chiller for precise temperature control and robotic arm integration. With a weld bead width of 1.5-4.5mm, it ensures tight sealing of radiator tank edges, meeting mass production demands.
Customer Feedback
After the equipment was put into operation, the results exceeded expectations. Welding quality remained stable, with customer feedback indicating a significant increase in weld acceptance rates and virtually no rework. Production line efficiency improved markedly, daily output increased substantially, and overall costs decreased due to reduced material waste.
The customer has decided to purchase an additional three units of 1500 W Laser Welding Machines in October 2025 for a new production line. The responsible party stated: “This equipment has enabled us to achieve more stable performance in welding dissimilar materials and has made batch production more efficient, providing strong support for our expansion plans.”
