AI Technical Summary
Traditional microchannel forming and composite plate welding methods are inefficient and costly, have insufficient interfacial bonding strength between dissimilar materials, and mechanical forming makes it difficult to achieve micron-level channel precision and metallurgical bonding between dissimilar materials in a single processing.
An ultrasonic roll forming device for microchannel composite plates is used. Through the synergistic effect of ultrasonic vibration, laser heating and roll forming, microchannel forming and composite plate welding are carried out simultaneously. The ultrasonic cavitation effect is used to remove the contamination layer on the surface of dissimilar foils, and the temperature of the foils is increased by laser heating to promote atomic diffusion at the interface.
This method enables the simultaneous processing of microchannel forming and composite plate welding, improving processing efficiency, enhancing the bonding strength of dissimilar metal composite plates, and solving the problems of long cycle time and insufficient bonding strength in traditional methods.
