分体式脉冲氩弧焊机的研究

Research on separating TIG inverter welding machine

为解决远距离施工时,由于氩气气路和焊炬过长给焊接质量造成的影响,研究了一种分体式脉冲氩弧焊机,该系统减少了氩弧焊单元对逆变焊接电源单元的干扰,并提高了焊接系统的可扩展性。单元模块均是独立的微处理器控制系统,通过通信协议进行信息的传递,通过软件算法使逆变焊接电源的外特性满足焊接工艺的要求。给出了系统硬件结构框图和软件流程,以及在强电磁干扰下的可靠性设计。

In this paper,it discuss a kind of separating digital TIG inverter,which is dedicated to the long distance welding occasion and can minimize the interference.The welding parameters transfer between the separating unit via the communication protocol. Through the flexible digital arithmetic,the inverter can generate the feature curves to satisfy the welding purpose.The scheme of hardware system and software diagram are given.
