butt welding process

A displacement threshold was used to control DC upset butt welding process, and constant pressure and varied pressure tests were carried out on Q235 a steel strips.

采用位移门槛电压控制焊接过程，对Q 235 - A钢进行了变压式和等压式扁钢带直流电阻对焊试验。

Butt welding machine process was introduced. 8031 single chip computer was used in controlling flashing current. Hence the flashing butt welding process automation is so achieved.

本文介绍了对焊机的生产工艺过程，并采用8031单片机对闪光电流控制，从而使闪光对焊工艺实现了自动化。

In the process of DC upset butt welding, the joint quality was strongly effected by the temperature distribution in the direction of the plate width.

板材直流电阻对焊过程中，对接端面沿板宽方向的温度分布对焊接接头的质量有很大的影响。
