Abstract

The invention relates to an ultrasonic magnetic field impact rolling optimization device for a linear weld joint of a plate. The ultrasonic magnetic field impact rolling optimization device for the linear weld joint of the plate comprises a rack, a welding platform, a first feeding mechanism, a second feeding mechanism and an impact hammer, wherein the plate is fixed on the welding platform; the rack is arranged above the welding platform; the first feeding mechanism is fixedly connected with the rack; the feeding direction of the first feeding mechanism is parallel to the linear weld joint ofthe plate; the second feeding mechanism is fixedly connected with the first feeding mechanism; the feeding direction of the second feeding mechanism is perpendicular to a plane of the welding platform; and the impact hammer is installed on the second feeding mechanism and faces the weld joint. The ultrasonic magnetic field impact rolling optimization device for the linear weld joint of the platefurther comprises an ultrasonic generator, an ultrasonic sheet and a magnetic field generator, wherein the ultrasonic sheet is installed on the impact hammer and connected with the ultrasonic generator; and the magnetic field generator is installed on the welding platform. According to the ultrasonic magnetic field impact rolling optimization device for the linear weld joint of the plate providedby the invention, ultrasonic impact rolling can be used for effectively improving the plasticity of weld metal, so that welding deformation and welding residual stress are reduced; and weld joint structure grains can be effectively refined by adding a magnetic field.

Description

technical field [0001] The invention belongs to the technical field of weld seam optimization, and in particular relates to a device for optimizing linear weld seam ultrasonic magnetic field impact rolling of plates. Background technique [0002] Welding is a method of connecting metals into a whole by means of local heating between metals and by means of the atomic bonding force inside the metals. Since the linear welding of plates is a complex process of instantaneous heating and rapid cooling, welding residual stress and welding deformation will occur. Welding residual stress will reduce the corrosion resistance and fatigue strength of structural parts, resulting in structural deformation, cracks and even brittle fracture of welded parts. At the same time as welding residual stress, there is also welding deformation. Welding deformation will not only affect the dimensional accuracy and overall stability of the weldment, but also reduce the assembly quality and affect the...
