摘要
小电流ＧＴＡＷ焊接过程中，引弧的可靠性及质量是关键技术之一。本文描述了接触短路引弧机理及其相应的控制技术，并提出了４个技术参数：接触短路时间、短路电流、引弧电流和引弧电流加入的时刻。
During GTAW Process with lower welding current,the reliability and quality of arc ignition are seen as one of key technologies.This paper discusses the mechanism of the contact-short-arc ignition and its control technology,in which the following four technical factors are put forward:contact-short time,contact-short current,arc igniting current and its put time point.
