【摘要】 本研究针对ＹＭ－３００ＳＶ焊机，利用ＦＡＮＵＣＳ－５机器人作为运动控制载体，进行ＣＯ２气体保护焊实验．针对焊接电流、电弧电压、焊接速度和保护气流量及成分这四种工艺参数对焊缝质量的影响展开研究，获得一套当焊丝直径为Φ１．２ｍｍ时，适用于２～３ｍｍ的Ａ３钢材的焊接工艺参数．更多还原

【Abstract】 From a series of experiments for CO2 metal arc welding, this paper listed four practical parameters which were welding current, arc voltage, welding velocity, flow of shielding gas and components of shielding gas. The experiment had been done with YM300SV welder, robot FANUC S5 and got a conclusion that this robotic arc welding system could weld A3 steel which thickness was 2～3 mm.更多还原
