摘　　要：在自行改造的搅拌摩擦焊机上通过大量试验,研究了T2-H62搅拌摩擦焊接技术,优化了搅拌头的材料、形状及尺寸,通过SNR(信噪比)试验设计,计算出紫铜和黄铜搅拌摩擦焊接工艺参数显著性顺序,并通过拉伸试验、硬度试验及弯曲试验测试了T2-H62搅拌摩擦焊接接头的力学性能,最终优化了搅拌摩擦焊接工艺参数。Friction stir welding of T2-H62 was investigated in this paper. Many experiments were carried on the welding machine modified by ourselves. The material, shape and dimension of the nib had been optimized. The significance sequence of processing parameters of friction stir welding had been calculated by signal-noise (SN) ratio experiments. The mechanical performance of T2-H62 welded joints was tested through tensile experiments, hardness tests and bending tests.
