Available Configurations
Available supply levels are Welding Head, Complete Welding Machine and Containerised Solution. The exact included equipment is stated on the individual product page and in the project specification.
Technology & System Architecture
Mobile machines combine flash-butt welding, hydraulic clamping and upsetting, post-weld flash removal where applicable (method of removal of excess upset where applicable), programmable process control and matched cooling/hydraulic systems. They can be integrated into mobile plants, containerised systems and complete road-rail welding complexes.
Key Advantages
Frequently Asked Questions
How should a customer select the correct model?
Selection starts with rail profile and cross-section, required force and stroke, productivity, operating conditions and integration concept.
What is flash-butt rail welding?
Flash-butt rail welding is a resistance welding process used to join rail ends by controlled electrical heating and upsetting. KZESO equipment applies the process in stationary and field applications, with continuous or pulsed flashing depending on the machine and welding task.
Can KZESO supply a complete mobile rail welding complex?
Yes. KCM007 is a complete mobile road-rail welding complex integrating a KZESO rail welding machine with road-rail mobility, autonomous power, hydraulics, cooling, controls and handling equipment.
