In year 2005 , our new main plant was built in jiading district , shanghai . hugong valve factory has also recently employed 556 people , including 158 technical engineers and 3 senior engineers . we also have more than 10 workshops for precise casting , hot forging and stamping , welding , heat treatment , finishing , machining and assembly 下设精密铸造热锻压焊接热处理精加工装配等十多个车间拥有数控加工中心等离子焊接机全自动气体保护焊半自动真空熔焊机超频真空热处理车球专用数控车床高效加工专机理化和探伤设备等各类加工检测设备300多台套。
In this thesis , an arc sensor based on fuzzy control is designed . through the change of welding current in waving , the arc sensor judges the excursion and provides the adjusting output , meanwhile , it transmits the data acquired to a personal computer to be displayed and analyzed 本文介绍了短路过渡的co _ 2气体保护焊电弧传感器，通过对摆动过程中焊接电流的变化来判别焊缝偏移情况，采用模糊控制得到控制输出，并将数据经串口通信传送到pc机上加以显示和分析。
