为了满足复合片与支柱焊接的温度极限和强度要求,研究对比几种常规焊接方法的局限性和可行性,确定了真空扩散焊接工艺;并研究和试验了焊件表面处理、中间夹层优选、焊接参数优化等具体工艺过程、以及对焊后试件性能的测定。通过大量的试验基本上解决了这一焊接难题,总结出了一套合理的工艺流程。 In order to meet the temperature and strength requirements of the composite sheet and pillar welding, the limitations and feasibility of several conventional welding methods were compared and the vacuum diffusion welding process was confirmed. The welding surface treatment, the middle interlayer optimization, the welding Parameter optimization and other specific processes, as well as the determination of the performance of the specimen after welding. Through a large number of tests basically solved this welding problem, summed up a set of reasonable process.
