PROCEDEU SI INSTALATIE PENTRU CONTROLUL TEMPERATURII SUDURII LA UN LAMINOR DE TEVI SUDATE PRIN REZISTENTE ELECTRICE DE INALTA FRECVENTA

摘要

A system for control of the welding temperature in a high frequency electric resistance weld pipe mill utilizes wall thickness, speed and weld current as input parameters in a control circuit based on the thermal power necessary to heat the skelp to the desired temperature. The control circuit includes adjustments for changes in dynamic forging forces.
