Mobile Flash Butt Welding Machine
Mobile Flash Butt Welding Machine
The Mobile Flash Butt Rail Welding Machine is a high-quality rail welding containerized machine with its unique modern design, as it is used to mount and manufacture long rails. These mobile welding machines can be transported both by rail and road, make moving to job sites easier, saving time, and making welding more efficient.
Advantages of the Mobile Flash Butt Welding Machine
The mobile flash butt welding machine is used for joining components, where the energy is transferred by the resistance heat created by the parts themselves. The rail produced is noticeably smoother than mechanically linked rail. The flash butt covers the whole welding cycle, from preheat, pre-flash, stead flash, boost, upset, forging, and removal of flash material.

It has a stable and high-quality consistency of welding. The process is very flexible since it can be used to make long welded rails and to convert short rails or long welded rails into continuous welded rails.

The computerized control system automatically controls the welding parameters for regular and pulse flashing modes. It ensures a consistent welding process and produces high-quality welding connections. The system provides a detailed analysis to review upon completion of each weld.
