  • Continuous flash butt-welding machine
    Patent number: 4159408
    Abstract: According to the invention, the continuous flash butt-welding machine supplied with power from a mobile diesel-generator power plant comprises a rectifier-charger the input of which is connected to the diesel-generator. The machine has a storage battery provided with a charge-discharge sensing element connected to the rectifier-charger. The machine also has an inverter with a unit for controlling the frequency and amplitude of the voltage at the inverter output. The inverter is connected to welding transformers and to a current transducer. The control unit is connected to the charge-discharge sensing element, the current transducer and a flashing value sensing element. The proposed invention makes it possible to reduce the installed power of the diesel-electric units of mobile power plants and to increase the life of the diesel engines and the thermal efficiency of the welding process.
