MIG(Bead) Braze Welding Process of Bearing Band for a Certain Bomb

为解决传统的压带、收带等工艺方式对大、中口径薄壁弹带合件加工时,加工难度大、废品率高、材料利用率低等问题,开展某弹弹带MIG(钎)焊工艺研究,形成较好的工艺技术规范,完成焊接小批量试制、理化分析、剪切试验及动态考核试验。焊接后的弹带合件满足产品图样和制造与验收规范要求,材料利用率、良品率得到大幅度提高,解决了大、中口径炮弹弹带焊接难题。结果表明该薄壁弹带合件MIG焊工艺加工方式可行,为新型弹种的研制开发奠定了基础。

This paper aims to solve problems such as high processing difficulty, high rejection rate, low stock utilization, etc. in processing large and medium diameter thin walled bomb with traditional technology on band press and recovery, through technical study on MIG braze welding of bearing band of a certain bomb, to form favorable technical specifications, complete the trial welding, physicochemical analysis, shear test and dynamic test of a small batch. The bearing band assembly after the welding met the requirements of product drawing and manufacturing and acceptance specification. The material utilization ratio and the yield of the product were greatly improved. It is feasible for the MIG welding process of the thin walled bearing band, which lays the foundation for research and development of the new type bomb.
