一、焊接参数的控制与记录闪光对焊过程大致分为预热—闪光—顶锻三个动作,加热过程由预热和闪光两个动作来完成。关于整个闪光对焊过程和能量法的分析详见本刊80年第1期。 1.加热温度的控制电流通过被焊工件和端面触点而产生热量,热量Q一部分产生于预热动作,一部分产生于闪光烧化动作,在有预热的情况下,主要由预热而产生 First, the control of welding parameters and records Flash Butt welding process can be broadly divided into preheating - flash - upset three movements, the heating process by the preheating and flashing two actions to complete. About the entire flash butt welding process and energy analysis, see the first 80 years of this issue. 1. Heating temperature control current through the workpiece and the welding end of the contact surface and generate heat, heat Q generated in part by the preheating action, part of the flash firing occurs in the case of preheating, mainly by preheating generated
