摘　　要：建立了高压环境下焊接过程多信息同步采集系统,开发了具有焊接过程电信号实时显示、数据采集及分析等功能的软件系统.利用该系统对高压环境下的脉冲MIG焊接电弧及熔滴过渡行为进行了研究.结果表明,高压环境下熔滴过渡时机较常压时有所提前,而国外学者提到的反向等离子流现象并未发现对焊接过程产生严重影响.A synchronous acquisition system of hyperbaric welding process was established.Software with the capability of real-time display of welding process signals,data acquisition and analysis was developed.Hyperbaric pulsed MIG welding arc and metal transfer behavior were studied using the system.The results indicated that the metal transfer in high-pressure environment was earlier than the behavior in atmospheric pressure environment.The serious impact of the reverse flow on the welding process was not detected.

关 键 词：干式高压焊接 同步采集 脉冲MIG 电弧 熔滴过渡
