Why choose the CR65 welding head?

The compact and simple design makes the flash-butt welding equipment kit, type CR65 extremely easy to operate and maintain. Its user-friendly interface and quick setup make it perfect for both experienced technicians and newcomers to rail welding. Additionally, the CR65’s advanced control system ensures precise and consistent welding results, even in the most challenging environments. 

The rail welding equipment type CR65 also features cutting-edge automation capabilities, enabling precise alignment and minimal manual intervention during the welding process. This reduces downtime and increases overall project efficiency.

In addition to the standard rail, the CR65 head can be used in welding grooved rails and crane rails (electrodes and shearing dies will be designed accordingly).

Its adaptability to multiple rail profiles makes the rail welding equipment type CR65 an indispensable tool for modern rail construction projects. By simply adjusting the electrodes and shearing dies, you can achieve high-quality welds across different rail types.

Advantages of the CR65 Welding Head

The rail welding equipment, type CR65 is very light, weighing only 3 tons and develops an upsetting force of 65 metric tons.

Its compact design allows it to be easily transported and deployed, even in projects with limited workspace.

The welding head jaws are optimized and tested to withstand long-term fatigue, the new design offers a firm clamping capability and a solid structure of the whole mechanism.

The high-grade materials and innovative engineering used in the rail welding equipment type CR65 ensure prolonged operational life, even in demanding environments.

The alignment of the 2 outer vertical reference blocks is easily done by a mechanical adjustment system, ensuring a precise movement up or down.

Its advanced alignment system guarantees consistent weld quality, reducing the risk of misalignment and enhancing track safety.

With the new type of electrode, the flash-butt welding equipment kit, type CR65 can weld rails with different profiles only by changing the contact pads (inserts). With a single type of electrode block, up to 3 types of rails can be welded.

The rail welding equipment type CR65 adapts seamlessly to a wide range of rail specifications, making it a cost-effective and practical choice for diverse rail projects.
