摘　　要：介绍了小口径炮弹弹带的摩擦焊技术。用该工艺装配弹带时弹体不需开槽滚花,焊后焊接热影响区宽度小,钢侧为不完全淬火组织,铜侧晶粒细化,焊接接头剪切强度≥200 MPa.摩擦焊弹带的炮弹通过多轮射击考核,证实弹带摩擦焊技术完全能满足小口径炮弹弹带装配的技术要求。A new radial friction welding band technology on small shell was proposed. Bands using this process were assembled to shell bodies without notch. The microstructure of the welding joint was discussed and serial tests were conducted. The results show that the microstructures of heat affected zone on steel side are.incomplete quenching with narrow width, and on copper side the microstructures are fine grains. The joint shear-strength is greater than 200 MPa. Series test firings indicate that the shells with radial friction welding bands can satisfy the assembly requirements of shell bands.
