Product Profile of Flash Butt Welder

Mechelonic engineers pvt. Ltd manufactures flash butt welding. Mechelonic engineers pvt. Ltd offers welding machines, engineering custom solutions, service backup and execution of turnkey projects. The flash butt welding machines are robust in construction and are precision-built for long trouble-free service. Each machine is submitted to rigorous proving tests before delivery, so that the machine is ready for immediate installation and operation at the customer`s works. These flash butt welders are specially designed for heavy duty applications, where repeatability in performance is important. Tooling and clamping devices are available for adapting these machines for the manufacture of railway shackles, automotive parts, starter ring-gears, wheel rims, link chains, etc. For accurate and consistent weld results, fully solid-state electronic controls are provided. Semi-automatic and fully automatic modes of operations are also possible. Flash butt welding machine incorporating plc and servo system are also available on request. These machines conform to the latest national / international standards.
