Machine Description

Copper Tube Sealing Metal Welder Ultrasonic Welding Machine

01: Application

Copper Tube Sealing Metal Welder Ultrasonic Welding Machine has specific bonding trait that adopts mechanical vibration energy of ultrasonic frequency to seal ends of aluminum and copper tube when assemble air conditioning HVAC system and refrigerator, capillary and bulb temperature sensor and products that require sealing and welding of copper and aluminum pipe, when the tube is ultrasonically welded, neither electric current nor high temperature heat source is applied to the joints, but under static pressure,the ultrasonic vibration energy is transmitted into molecular realignment energy, deformation happen, and internal temperature rise, solid phase welding occurs when the compacted tube reach the re-crystallization temperature, therefore, it effectively overcomes the spatter and oxidation caused for resistance welding, It is generally believed that in the initial stage of ultrasonic welding process, the tangential vibration removes the oxides on the metal surface, and the protruding part of the rough surface produces repeated micro-welding and destruction, which increases the contact area and increases the temperature of welding zone, high, plastic deformation occurs at the interface of joints,in this way, under the action of contact pressure, when they approach each other to the distance at which atomic gravity can act, a solder joint is formed,pneumatic force also cal exert cutting in the sealing process to attain completed process

03:Working Principle  

Copper Tube Sealing Metal Welder Ultrasonic Welding Machine has the sample traits of universal ultrasonic metal welding machine except for end trimming cut, the ultrasonic transducer converts the ultrasonic high-power oscillating signal into mechanical energy of the corresponding frequency, and applies it to the interface of the metal tube to be welded, so that the joint of the metal tube generates heat instantly, and then activates the particles in the metal lattice. So that the molecules where the metal tube compacts close is interpenetrated and sealed together, during the process, there is no current passing through the tube, and no welding arc is generated,since ultrasonic welding does not have problem such as the conduction and resistivity, it is undoubtedly an ideal tube end sealing solution
