【摘要】 本文应用图象温度检测法对各影响因素对温度场变化的作用效果进行观察。试验结果表明：焊前改变焊机副边空载电压及初始工件干伸长可以在较大范围内改变温度分布；而焊接过程中改变反馈参考电压比、脉动速度及连续闪光送进速度可以在较小范围内调节温度场的变化。更多还原

【Abstract】 The effectiveness of the variables on welding temperature field is observed with TV image measurement method.The modification of secondary no load voltage and initial clamping distance set before welding can in a large range modify the welding temperature distribution of each specimen.on the other hand,the modification of the ratio of feedback reference voltage,pulse speed and continuous flash feeding speed can in certain range change that temperature field.更多还原
