Embodiment 1

[0024] Taking aluminum alloy as an example, the welding principle is as follows: figure 1 As shown, the actual welding method is as follows image 3 As shown, the groove form is as image 3 As shown, the thickness of the aluminum alloy plate to be welded is 2 mm. During the welding process, the aluminum alloy plate is first installed on the workbench and fixed with flexible tooling. Turn on the power supply of the ultrasonic generator and the pulse heat-resistant equipment, set the ultrasonic welding parameters (power 3KW, amplitude 25μm, speed 8mm / s) and pulse heat-resistant equipment parameters (current 4KA), and the high-frequency current acts on the contact interface of the two metal plates The heating and softening of the interface metal is realized at the interface. After everything is ready, welding along the direction shown in the figure can obtain a high-quality solid-phase cold welding seam. In order to optimize the welding process, a low-melting point aluminum-sil...

Abstract

The invention relates to an ultrasonic roll welding and resistance internal heat composite metal seam welding device. The welding device is characterized by being provided with an ultrasonic roll welding mechanism and a resistance internal heat welding mechanism, the ultrasonic roll welding mechanism is provided with an ultrasonic generator and a roll welding pressure head (14), the two sides of the roll welding pressure head (14) are correspondingly provided with a transducer (1) and a transducer (12), the resistance internal heat welding mechanism is provided with a medium frequency / high frequency resistance welding power supply used for outputting medium / high-frequency pulse currents, electric pulses output by the medium frequency / high frequency resistance welding power supply are sentto conductive rolling wheels through electrode supports, the conductive rolling wheels are in contact with a metal plate to be welded, two paths of electric pulse signals which are the same output bythe medium frequency / high frequency resistance welding power supply are sent to the two electrode supports correspondingly, the two electrode supports are correspondingly connected with the two conductive rolling wheels, and the two conductive rolling wheels are used for outputting electric signals to the contact surface of the metal plate to be welded. According to the welding device, the joint softening phenomenon caused by melting welding can be effectively avoided, the welding defects such as air holes are overcome, and a wide application prospect is realized.

Description

Technical field: [0001] The invention relates to the field of welding technology, in particular to an ultrasonic roll welding and resistance internal heat composite metal seam welding device that can effectively avoid joint softening caused by fusion welding and eliminate welding defects such as pores. Background technique: [0002] As an effective metal joining method, arc welding technology is widely used in rail transit, aerospace and other fields. With the continuous development of welding technology, welding methods using high-energy beams such as plasma, laser, and electron beams as heat sources have emerged to further improve the quality and efficiency of traditional welding methods. However, for the welding of metal materials, the above fusion welding methods often cause defects such as weld joint softening and pores, which seriously affect the application range and service life of metal welded components. This problem was not improved until the emergence of frictio...
