Abstract

The invention provides an ultrasonic vibrating liquid phase welding device for aluminum, aluminum alloy and other composite material, which comprises control box installed with ultrasonic generator inside, control knob and wire connecting post on the panel, clipping working bench on the upper surface of the control box, bracket on the top of the control box, temperature display panel and ultrasonic welding head installed on the bracket, one end of the electrical thermocouple connecting with the inspecting work piece, the other connecting with the temperature control module inside the control box through the wire connecting post on the control panel, temperature control module connecting with the temperature display panel, displaying the temperature from the display, ultrasonic welding head connecting with the ultrasonic generator through signal wire, with pressurizing device, energy changing device, width changing bar on the ultrasonic welding head, with the rear two connected and to connect with the first. Without using brazing flux, it can realize the welding of aluminum, aluminum alloy and other composite material.

Description

1. Technical field [0001] The invention relates to a welding equipment, in particular to an ultrasonic vibration liquid phase welding equipment. 2. Background technology [0002] There is a dense oxide film (Al 2 o 3 ), if the removal is not complete during the brazing process, the wetting and spreading ability of the brazing filler metal to the base metal will be greatly reduced, which will seriously affect the forming and final performance of the joint. At present, the brazing of these materials either uses flux to remove the oxide film through chemical reaction, or uses a vacuum welding environment to avoid the formation of thick and dense oxide film to achieve welding. However, on the one hand, the use of flux increases the cost. On the other hand, flux is generally corrosive. If the cleaning after welding is not strict, the joints are prone to corrosion damage during service; welding in a vacuum environment limits the welding performance. Flexibility, the welding of ...
