Overview: In automotive manufacturing, welding quality directly impacts vehicle safety and reliability. A renowned Chinese automotive company introduced the Canroon CR2100 series induction heating machine for critical copper tube component welding, achieving significant breakthroughs in both efficiency and quality.

Customer Background

Our customer is a leading Chinese automobile manufacturer with substantial presence in both traditional fuel vehicles and new energy vehicles. As vehicle models iterate rapidly and production volumes continue to increase, the company faced higher demands for production efficiency and welding quality. The limitations of traditional processes became increasingly evident, particularly in the welding of critical copper tube components such as air conditioning pipelines and cooling systems.

The Challenge: Limitations of Traditional Processes

Prior to introducing the CR2100 series, the customer primarily used flame brazing for copper tube connections . This traditional method presented several pain points:

• Large heat-affected zone: The flame heating range was difficult to control precisely, easily causing thermal damage to surrounding precision components

• High energy consumption: Significant heat energy dissipated into the air, resulting in low energy utilization efficiency

• Inconsistent quality: Heavy reliance on operator skill made it difficult to ensure welding consistency

• Safety hazards: Open flame operation posed fire risks and imposed strict requirements on the production environment

• Environmental pressure: Generated smoke and harmful gases, contradicting green manufacturing trends

As production volumes ramped up and quality standards increased, these pain points increasingly constrained production efficiency. The customer urgently needed a more precise, efficient, and safe heating solution.

The Solution: CR2100 Series Induction Heating System Application

After multiple rounds of technical comparisons and on-site testing, the customer ultimately selected the Canroon CR2100 series induction heating system for copper tube brazing on their production line.

Core Technical Advantages

1. Precise Temperature Control for Consistent Welding Quality
The CR2100 series utilizes a PID closed-loop temperature control system that precisely regulates heating temperature and time, ensuring every joint is completed under optimal process parameters . Induction heating acts directly on the workpiece itself with a minimal heat-affected zone, effectively protecting seals and electronic components around the copper tubes.

2. Rapid Heating for Enhanced Production Efficiency
The equipment can heat copper tubes to over 1000°C within seconds, significantly reducing single-piece welding time . Coordinating with automated production line cycles, overall production efficiency increased by more than 30%.

3. Clean and Environmentally Friendly, Supporting Green Manufacturing
The induction heating process produces no open flame, no smoke, and no harmful gas emissions , thoroughly improving the workshop environment while helping the customer achieve carbon neutrality goals.

4. Flexible Integration for Diverse Workpiece Requirements
The CR2100 series supports multiple configuration options, allowing quick changeover of induction coils based on copper tube diameter, wall thickness, and joint shape . The equipment integrates seamlessly with robots for automated welding operations.

5. Energy Savings and Cost Optimization
Compared to traditional flame heating, induction heating improves energy utilization efficiency by over 50% . Precise energy control reduces material overheating and scrap rates, significantly lowering comprehensive production costs.
