Research and Development of Tubular Products Magnetic Pulse Welding-Forming Technology for Space Engineering

摘要

The analysis of the aircraft onboard cables design made by the authors has shown that it is most expedient to reduce the weight of the bonding of electrical connectors through replacing a molded housing of the plug connector by a lightweight one, while keeping to the requirements of shielding the cable bonding assembly from radio interference. 0.15/0.2 mm thick aluminum foil was chosen as a material for the tubular lightweight housing. To obtain lightweight tubular products for space engineering it was suggested to use magnetic impulse welding-forming (MIWF), which applies integrated force and thermal action on the workpiece. We described the physical nature of MIWF process and defined the ranges of energy parameters affecting the quality of welded joints: operating voltage of the battery charge of capacitors, capacity of the equipment storage unit, inductance of the working tool-inductor-characterized by a number of turns. The combination of these parameters determines the energy and the duration of the action to the workpiece. The results of the experimental studies are provided. The industrial technology has been developed.
