FIELD: mechanical engineering; welding facilities. SUBSTANCE: invention relates to sets furnished with devices for loading group of blanks into working chamber and welding the blanks at one evacuation step in working chamber. Improved uniformity of blank heating and reduced weight of faceplate and its turning forces are provided by installing faceplate manual turning lever under chamber, lever being mechanically coupled with faceplate shaft. Heater is rigidly secured on side wall of vacuum chamber at height exceeding possible height of blanks to be welded installed on faceplate. Stop is mounted over heater on one axle with heater. Power rod is arranged under faceplate provided with holes for passing of power rod and arrangement of blanks. Axes of holes are alternately aligned with power rod axis at turning of faceplate through preset angle. Power rod drive can be mechanical or hydraulic. Stop is installed on piston of hydraulic cylinder provided with pressure gauge brought out of chamber. EFFECT: improved heating of blanks, reduced weight of faceplate and its turning forces. 9 cl, 2 dwg
