Product Description

CNC Pneumatic 3Mm MFDC Projection Welder for Piston Rod Resistance Welding



Video Demonstration




Product Overview

This projection welding machine is specifically engineered for high-precision piston rod welding. It is widely used in the production of components for automobiles, motorcycles, hydraulic and pneumatic systems, engineering machinery, and automotive manufacturing. The machine accommodates a wide range of workpiece configurations and supports different center distances, piston rod diameters, and ring shapes.


Advanced medium-frequency DC technology ensures consistent weld quality with minimal ring deformation and stable center-to-center distance after welding. The piston rod surface remains free of visible marks, making this system ideal for heavy-duty, high-volume production environments.

Key Technical Advantages

High-Precision Welding Control

Smart motors or valves control welding pressure with only 1% error, ensuring consistent weld quality across every workpiece.

Seamless Production Integration

Automated material handling with vision-based alignment or mechanical fixturing enables uninterrupted batch welding, increasing throughput by 40% while maintaining positional accuracy within ±0.1 mm.

Intelligent Process Management

Multiple welding parameter sets such as pressure, current, and time curves can be stored and switched with one click for different piston rod specifications. Real-time monitoring alerts operators to abnormalities automatically.

Strong Adaptability and Reliability

Compatible with piston rods of various specifications; water-cooled electrodes and high-temperature-resistant construction support continuous operation without performance degradation.

Safety and Maintenance Convenience

Integrated air and water pressure sensors automatically shut down the machine in case of water shortage or insufficient pressure. Modular design minimizes electrode replacement and maintenance time.

Applications

Industry Typical Workpiece Welding Mode
Automotive Shock absorber piston rods Medium frequency projection welding
Motorcycle Suspension piston rods Medium frequency projection welding
Hydraulic and pneumatic systems Cylinder piston rods and ring parts Projection welding with servo pressure control
Engineering machinery Heavy-duty piston rods, coupling rings Automated multi-projection welding


Working Principle



The workpiece is loaded between electrodes and pressed by precise pneumatic force at the projection points. A high-current, low-voltage medium-frequency DC pulse passes through the contact area, generating resistance heat that fuses the material. The control system regulates current, pressure, and time in real time, producing consistent weld nuggets with minimal deformation. Automated loading and unloading complete the cycle for continuous production.

Frequently Asked Questions

What materials and thicknesses can this projection welder handle?

This machine is designed for piston rod projection welding with A3 steel capacity up to 3.0+3.0 mm on the standard model, and up to 6.0+6.0 mm on larger power frequency models.

Does the machine support automated production?

Yes. The system can integrate automated material handling, an independent vibration disc that holds up to 500 workpieces, and fully automatic welding, achieving up to 720 pieces per hour.

How do I switch between different piston rod specifications?

The human-machine interface stores hundreds of process formulas. Operators can switch specifications with one click, and the machine automatically adjusts welding parameters and moving components.

What after-sales services are included?

We provide free spare parts, field installation, commissioning, training, online and video support, plus a 1-year warranty. Our overseas technical teams can also provide on-site service in many countries.

Is the machine suitable for continuous heavy-duty operation?

Yes. Water-cooled electrodes, high-temperature-resistant components, and automatic air/water pressure safety shutdown ensure stable performance during long production runs.
