热塑性复合材料在民用飞机制造领域的应用近年来发展迅速,焊接技术是热塑性复合材料制造过程中的关键环节之一,是零件装配成部件必不可少的工艺过程。感应焊接技术是目前应用的几种焊接方法之一,通过感应线圈产生高频电磁场,加热电感材料使接头熔融,加压重新凝结后完成焊接过程。感应焊接工艺过程稳定,可实现连续化操作,受人为因素影响较小,是将来热塑性复合材料连接的重要发展方向。立足于提供此技术的基本原理,介绍此技术已取得的最新进展。同时,还介绍一些实验过程和实验装置。最后,还尝试简易描述焊接区域的温度场分布,以便于焊接实验者进行工艺参数评价。
The application of thermoplastic composites in the field of civil aircraft manufacturing has been developing rapidly in recent years. Welding technology is one of the key links in the manufacturing process of thermoplastic composites. It is an indispensable process for assembling parts into components. Induction welding is one of the several welding methods currently used. The induction coil produces a high-frequency electromagnetic field, heats the inductor material to melt the joint, and recompresses after pressurization to complete the welding process. Induction welding process is stable, continuous operation can be achieved, less affected by human factors, is an important future direction of the thermoplastic composite material connection. Based on the basic principle of providing this technology, we introduce the latest progress made in this technology. At the same time, also introduced some experimental process and experimental device. Finally, we also try to describe the temperature distribution in the welding area briefly so that the welding experimenter can evaluate the process parameters.
