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。
The preheat flash welding process for welding large section workpieces consists of four stages. The role of each stage varies, and controllable parameters are numerous. The quality of welding depends entirely on the welding process parameters set. Based on the experiment, this paper makes an in-depth analysis of each stage of preheating flash welding and their respective parameters, and qualitatively studies the relationship between parameter values and welding quality.
