摘　　要：采用微型储能焊机对Φ2.5 mm的异种棒材进行储能焊接研究。采用正交试验设计方法进行焊接参数优化设计,研究了焊接工艺参数与焊接接头抗拉强度和断裂特征的关系。试验结果表明,当焊接参数采用电压195 V,电极压力15 N,电容9 900μF时,焊接接头拉伸强度可达到708.23 MPa。Using mini welder , the study focuses on storage capacity welding of dissimilar bar with the size of Φ2.5 mm.A parametric optimization is completed with orthogonal disign .The effects of welding parameters on the tensile strength and fracture characteristic have been studied through a series of experiments using orthogonal experiment method .The results show that ,at the condition of welding voltage 195 V, capaci-tance 9 900 μF and pole pressure 15 N, the tensile strength of welded joints can reach 708.23 MPa.
