开发了一套GTAW焊机器人配套用送丝装置。在CO2 焊送丝机基础上增加了一级减速器 ,调速电路采用自行设计的测速负反馈控制系统。送丝速度调节范围达到 50～ 350 0mm/min ,网压波动和送丝阻力变化时 ,送丝速度变化率在1 5%以内 ,完全满足自动GTAW焊的需要。
Developed a GTAW welding robot supporting wire feeding device. A CO2 reducer is added on the basis of CO2 welding feeder, and the speed control circuit adopts the self-designed speed feedback control system. Wire feed speed adjustment range of 50 ~ 350 0mm / min, wire pressure fluctuations and wire feed resistance changes, wire feed rate of change within 15%, fully meet the needs of automatic GTAW welding.
