| 摘 要： | 脉冲电源应用于双熔敷极焊条电弧焊,采用正交试验研究分析脉冲参数对焊缝熔深的影响.结果表明,脉冲参数的变化引起焊缝熔深的相应变化,脉冲参数对焊缝熔深的影响程度由大到小的次序为峰值电流、频率、占空比、基值电流.在试验范围内获得较大熔深时的脉冲参数分别是峰值电流为230~240 A,频率为3.3~3.7 Hz,占空比为48%...

| Abstract: | Effects of pulsed parameters on weld penetration with the method of orthogonal experiment were researched when pulse power supply was applied to twin deposition electrode arc welding.Results of orthogonal experiment indicated the change of pulsed parameters could result in the corresponding change of weld penetration,and the descending order of pulsed parameters influencing weld penetration was as follows: peak current > frequency > duty ratio > base current.Greater penetration could be obtained with these ... |
