| 摘 要： | 在焊接电流确定的条件下，引弧瞬间的焊机输出电压反映了焊接电缆长度、截面积以及连接情况等重要信息。本研究装置是基于MC68HC11单片机控制的逆变焊机电弧推力自适应的控制系统，首先通过对引弧瞬间焊机输出电压的实时检测，实现了电弧推力拐点电压随焊接电流及焊接电缆长度，截面积等改变而自动；然后通过对焊接电弧 实时检测与模糊处理控制焊机的输出电流，从而使MMA手工电弧焊的以推力控制具有很强的自适应能力。

| Abstract: | When welding current is fixed,some important information such as length and section area of welding cable,connection of ground wire can be shown by output voltage of instantaneous arc striking.The arc force self adapt control system of invert arc welding machine is based on single chip micro processor MC68HC11.First,detecting the output voltage of arc striking in the real time,the arc force voltage can be auto adjusted along with the changing of the length and section area of welding cable.Then inspecting welding voltage in the real time and controlling welding current by fuzzy process, therefore the arc force control of manual metal arc welding is provided with powerful self adaptability. |
