Embodiment 1

[0021]figure 1A schematic diagram of a welding system for stirring friction welding according to the embodiment of the present application.

[0022]Such asfigure 1As shown, the welding system of stirring friction welding of the present invention, including:

[0023]The stirring head 11 is used to weld both the bonded base material 2 to form weld;

[0024]The cooling device is used to cool the weld during welding.

[0025]The welding system of the stirring friction welding is carried out in the agitating head, and the cooling device is lowered by the weld to prevent or reduce the weld to form an intermetallic compound at the weld by cooling. However, there is less distribution of crispy phase, and the mechanical properties of the weld joint are high.

[0026]Among them, iffigure 1As shown, the arrow on the stirring head represents the direction of rotation of the stirovery head, and the arrow on the base material to be welded represents the welding direction.

[0027]In implementation, the welding sys...

Embodiment 2

[0064]The welding method of stirring friction welding in the present application embodiment, using an example of stirring friction welding system, including the following steps:

[0065]While welding at the stirring head, cooling is performed at the weld.

[0066]The welding method of stirring friction welding is carried out in the agitating head, and the weld is cooled when the blender is welded to form a weld. Avoid or reduce the formation of intermetallic compounds at a weld by cooling, thereby having a small distribution of brittle phase, and the mechanical properties of the weld joint are high.

[0067]In the implementation, the step of cooling the weld when the blender to be welded is formed, and the weld is used to cool the weld, including:

[0068]Get the perceived temperature of the temperature sensor, transmit the perceptual temperature of the temperature sensor to the cooling device;

[0069]According to the perceptual temperature of the temperature sensor, the cooling device controls t...

Abstract

The embodiment of the invention provides a welding system and a welding method for friction stir welding. The welding system comprises a stirring head used for welding two to-be-welded base materials to form a weld joint, and a cooling device used for cooling the weld joint during welding. The welding method comprises the following steps: when the stirring head welds the two to-be-welded base materials to form the weld joint, the weld joint is cooled. According to the embodiment of the invention, the technical problem that the mechanical property of a welding joint formed by welding dissimilar materials through friction stir welding is poor is solved.
