The invention relates to a method and a device for controlling a residual stress on a stir friction welding surface. According to the method, an insulation box capable of moving along a stirring head is adopted to insulate the weld joint and parent metal after welding, and then furnace cooling is performed so as to reduce the residual stress on the stir friction welding surface. The device mainlycomprises a sucking-disc type fixture, the insulation box and control equipment, wherein the insulation material mainly comprises fire bricks, asbestos and steel plates. During welding, the insulation box moves along the stirring head and insulates the welded workpiece continuously; and after the welding, the whole workpiece enters the insulation box to be insulated and is cooled with the furnaceafter being insulated for a certain time so as to control the residual stress on the welding surface and the deformation, wherein the insulating temperature is the critical temperature of the heat treatment of the materials. The device realizes full automation in the whole welding process and avoids the reduction in the welding quality due to a human factor. The method and the device have the advantages of simple device, convenient operation, high technical economic benefit, and high welding quality of the stir friction welding.
