INSTALLATION FOR MECHANIZED PLASMA FUSION OF SHAFTS

摘要

FIELD: welding equipment, namely repairing shafts and other parts by plasma fusion. SUBSTANCE: installation is equipped with mechanisms for rotating part and for moving plasmatron with device for feeding addition material. Installation also includes pyrometer for measuring temperature of surface in front of leading end of plasma arc or behind it and control device connected with said pyrometer. Said control device includes mechanism for lengthwise motion of plasmatron and device for feeding addition material until achieving temperature of said surface almost equal to temperature of limit heat absorption of part at selected mode. EFFECT: improved design. 1 dwgb
