摘　　要：用于焊接大截面工件的预热闪光焊工艺包括四个阶段。每个阶段的作用各不相同 ,而且可控参数众多。焊接质量的好坏完全取决于焊接工艺参数的设定。本文在试验的基础上对预热闪光焊的每个阶段及其各自参数作用作了深入分析 ,定性研究了参数取值与焊接质量的关系。There are four phases and dozens of parameters in preheating flash butt welding technology used for great section workpiece's welding. The quality of welding is decided absolutely by the effects of parameters. In this paper, thorough analyses on different phases and parameters are made based on experiments. The relations between parameters and welding quality are also studied.
