ANAND viscoplastic constitutive equation was introduced into the FE model for calculation of the reduction of welding residual stresses during the post weld heat treatment.
将ANAND粘塑性本构关系引入到焊后热处理消除残余应力的有限元计算中。
The welding current, arc voltage, preset current, the period and ratio of pulse, base current, down slope time, gas pre and post flow time are sampled, calculated and controlled by microprocessor.
单片机对焊接电流、电弧电压、电流给定、脉冲周期、占空比、基值电流、收弧电流衰减时间、前气和后气时间等焊接参数进行采样、计算和控制。
The result shows that it is more reasonable, safe and reliable to adopt procedure with warm up before welding and post heat treatment after welding.
结果表明：采用焊前预热和焊后热处理的焊接工艺方案所获得的焊接接头比不采用以上措施获得的焊接接头更为合理，应用更安全、可靠。
