ELECTRIC ARC ADDITIVE DEVICE, CONTROL METHOD FOR ELECTRIC ARC ADDITIVE DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2023/236256

A1

Disclosed are an electric arc additive device, a control method for the electric arc additive device, and a storage medium, used in the field of additive manufacturing. The electric arc additive device comprises: an additive welding torch, used to melt a wire material to add material to a workpiece to be processed; a mechanical vibration apparatus disposed below the workpiece; an ultrasonic auxiliary apparatus disposed at a side of the additive welding torch; and a control apparatus used to control the ultrasonic auxiliary apparatus to form an ultrasonic field below the additive welding torch and, when the additive welding torch is welding a position to undergo additive machining, controlling the mechanical vibration apparatus to perform mechanical vibration in different modes. During the additive welding process, mechanical vibration may reduce the accumulation of thermal stress, and after the additive welding torch finishes working, mechanical vibration in another mode is generated to diminish the residual stress in the workpiece; the coordination of these two different modes of mechanical vibration may significantly reduce stress in the workpiece, and minimize the occurrence of cracks in products of electric arc additive manufacturing.
