Metal Doctor (MD) is a pulsed micro-welding process that is being used increasingly for small scale and precision coating and repair of high value components.
金属医生是一种脉冲微弧焊接过程，可以用来在小面积范围内实现精密涂层和用来修复高附加值的部件。

The greater stability of these power sources allows very low currents to be used particularly for micro-TIG welding and largely replaced the plasma process for micro-welding operations.
这些电源稳定性较好，允许专用于微型TIG焊的电流非常低，可以大量取代等离子方法用于微型焊接作业。
