摘　　要：文章通过分析小孔径氧乙炔钴基合金堆焊过程中出现的火焰燃烧不稳定、回火爆枪、操作空间受限及堆焊层硬度超标等问题,以氧乙炔焊炬为问题切入点,研制专用水冷焊嘴及后接部件,通过专项试验证焊炬的安全性、可靠性及堆焊工艺实施的可行性。In this paper, the problems of flame combustion instability, backfire, operating space limitation and surfacing layer hardness in the process of small pore oxygen acetylene base alloy surfacing welding are analyzed, and the oxygen acetylene torch is taken as the starting point. The safety, reliability and feasibility of surfacing welding process were studied by special test on the safety and reliability of the welding torch.
