Synchronous heating stress deformation control system and method for robot electric arc additive shaft part

The invention discloses a synchronous heating stress deformation control system and method for a robot electric arc additive shaft part. The synchronous heating stress deformation control system comprises annular electromagnetic induction heating units, wherein the multiple layers of annular electromagnetic induction heating units are stacked to form a heating cylinder; each layer of heating units is connected to a computer and independently controlled; the inner side of each layer of annular electromagnetic induction heating units is connected with temperature sensors; the interior of the heating cylinder is a working area; the upper end of a lifter is connected with a horizontal workbench; a base plate is assembled on the horizontal workbench; and a six-axis robot carries out additive manufacturing on the base plate. According to the synchronous heating stress deformation control system and method, each layer is independently heated during additive manufacturing, after one layer of additive manufacturing is
