摘要
介绍了研制机器人MIG/MAG焊用ZP7-400逆变电源中处理的几个问题,将整个焊接过程分为引弧期和焊接期,并在此两个时期中采取不同的控制要点,在引弧期中充分提高电源响应速度,力求提高引弧成功率和快速建立稳定弧长,在焊接期中则采用复合型外特性和电子电抗器以提高焊接稳定性和抑制飞溅,为此,从焊接外特性选取、提高引弧成功率和控制动特性等方面进行了试验,其研究结果已用于NZM-400弧焊机器人MIG/MAG焊接系统和NBC-400焊机中。
This paper presents several study results on research of MIG/MAG power inverter for robot arc welding, with emphasis on welding dynamics. For dip transfer, the welding process may be divided into ar(?) striking period and welding period, and be controlled respectively according to its own speciality. In the arc striking period, the key is to fully develop the System response so that a sound ar(?) ignition rate and a fast-established stable ar(?) can be obtained, while in the welding period the important factors ar(?) to stabilize the welding process and to depress the welding spatter by, say, complex static characteristics and electronic reactor. So the authors studied these problems in the aspects of the static characteristics selection, the improving of ar(?) striking, the control of welding dynamics, etc. Results have been applied to the prototype of NZM-400 MIG/MAG robot welding System and also to NBC-400 semiautomatic MIG/MAG welding machine.
