In all cases, of course, the current must flow or the weld cannot be made.
在所有情况下，当然，目前一定要流或焊缝不能作出。

Use the Weld Shield Gas Flow Switch to give your PLC or control system a signal that allows for simple detection of flow problems.
使用焊接保护气体流量开关，让您的PLC或控制系统的信号流问题的简单检测允许。

The result shows that the velocity field changes with the increase of space from shoulder and stir tool and the flow of weld metal from top to bottom and stir zone to rotation zone also weakens.
