Embodiment 1

[0027] like Figure 1~Figure 4 The shown static shaft shoulder friction stir welding device applied to the splicing of container side walls includes a drive motor 8, a stirring needle 9 detachably connected to the shaft end of the output shaft 5 of the drive motor 8, and a drive motor housing or a stirring needle 9. The static shaft shoulder 1 fixedly connected to the shell of the welding device, the lower end of the static shaft shoulder 1 is provided with a shaft shoulder hole 101, the lower end of the stirring needle 9 passes through the shaft shoulder hole 101 and protrudes out of the static shaft shoulder 1, and the stirring needle 9 and the shaft shoulder hole 101 There is a gap between the inner walls, a magnetic field vector module 2 is sleeved outside the lower end of the static shaft shoulder 1, the magnetic field vector module 2 is in the shape of a circular ring, and four pairs of heating coils driven by independent power sources are uniformly distributed inside the...

Embodiment 2

[0035] like Figure 1~Figure 4 As shown, the static shoulder friction stir welding method applied to container side wall splicing adopts the static shoulder friction stir welding device applied to container side wall splicing described in Embodiment 1, including the following specific steps:

[0036] S1. Fix the plate 12 to be welded on the telescopic table 6 with the clamping device 7 .

[0037] S2. According to the size of the stirring needle 9 and the thickness of the plate 12 to be welded, adjust the length of the adjustable cable tube bracket 11 and the length of the stirring needle 9 extending from the static shaft shoulder 1, thereby adjusting the position of the magnetic field vector module 2, so that the magnetic field vector The lower end face of the module 2 is flush with the lower end face of the static shaft shoulder 1 .

[0038] S3. Turn on the power supply, start the drive motor, drive the stirring needle 9 to rotate through the output shaft 5 of the drive moto...

Abstract

The invention relates to a static shaft shoulder friction stir welding device and method applied to container side wall splicing. A magnetic field vector module is arranged on the periphery of the bottom of a static shaft shoulder, and a magnetic field which rotates at a high speed relative to a to-be-welded plate with a stirring needle as the axis is generated through the magnetic field vector module; and the to-be-welded plate in the welding area is preheated, so that the welding efficiency of container side wall splicing is greatly improved, and the technical problems that traditional static shoulder friction stir welding is low in efficiency, even a stirring needle is broken, and welding fails are solved. Meanwhile, the welding area of the to-be-welded plate can be heated and pulsating vibration can be generated through the magnetic field vector module, the metal flowability in the welding process is improved, particularly, the metal flowability at the bottom of the to-be-welded plate is improved, a cavity behind a stirring needle is filled in time, the defect of dispersively distributed cavities is overcome, and the welding quality is improved. Grain refinement of a welding seam structure is facilitated, the welding seam structure is more uniform, the plastic deformation resistance of materials is reduced, the stirring head loss is reduced, and the welding quality is improved.

Description

technical field [0001] The invention relates to a static shaft shoulder friction stir welding device and method applied to the splicing of container side walls. Background technique [0002] The side coaming of the container is generally butt-welded by multiple sheets of steel plates. Due to the long welding seam, traditional welding methods require a large investment in gas shielding costs and welding wire costs, and the flatness of the welding seam is difficult to control and difficult to control. subsequent processing. In order to reduce the cost and improve the quality of the weld, our company chooses to use the static shoulder friction stir welding device to replace the traditional gas shielded welding, which greatly reduces the input of welding raw materials and improves the quality of the weld. [0003] However, in the static shoulder friction stir welding, due to only the friction and extrusion of the stirring needle, the heat generation is low, the resistance of th...
