Abstract

The invention discloses an ultrasonic and electromagnetic pulse composite welding device and a composite welding method. The composite welding device comprises a device base, a composite welding component and a welding part clamping device; the composite welding component is installed above a worktable of the device base; the welding part clamping device is installed on the worktable and can be lifted up and down; the composite welding component comprises a control box, an ultrasonic transducer, an amplitude-change pole and a welding head; the upper end of the ultrasonic transducer is installed inside the control box; the lower end of the ultrasonic transducer is connected with the amplitude-change pole; the lower end of the amplitude-change pole is connected with the welding head; and anelectromagnetic coil is positioned inside the welding head. According to the composite welding method, firstly welding positions of two welding plates are subjected to ultrasonic softening and oxide film removal by utilizing ultrasonic energy; and subsequently the welding positions are applied with transient high voltage electromagnetic force generated by the electromagnetic coil sot that weldingformation of the welding positions is realized. The composite welding device can meet the welding requirements of various dissimilar-material plates; and the composite welding method can improve the stability of the welding positions.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to an ultrasonic and electromagnetic pulse composite welding device and a composite welding method. Background technique [0002] Welding is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic materials such as plastics. Welding achieves the purpose of joining through the following three ways: First, fusion welding, heating the workpiece to be joined to make it partially melt to form a molten pool, and the molten pool is cooled and solidified before joining. If necessary, fillers can be added to assist. It is suitable The welding process of various metals and alloys does not require pressure; secondly, pressure welding, the welding process must exert pressure on the weldment, which belongs to the processing of various metal materials and some metal materials; The metal material with low melting p...
