中文摘要：

介绍了几种多电极电弧焊接技术的基本原理、工艺特点及发展历程,主要包括Tandem焊、三丝焊、等离子-MIG复合焊、多电极并联钨极氩弧焊、旁路电极GMAW焊接工艺、Arcing Wire GTAW焊接工艺、叉耦合电弧焊接方法等,根据耦合形式的不同将其分为共工件端弧焊技术、共焊枪端弧焊技术及交叉耦合弧焊技术三类,并展望了多电极电弧焊接技术未来的研究动向。

英文摘要：

Brief int.＇oduction has been given to the multi-electrode arc： welding technology,including Tandem arc welding.3-electrode MAG high speed horizontal fillet wehting process.plasnm-MIG welding,C-TIG,double-electrode t;MAW,arcing wire GTAW,Tri-are DE welding tu＇ocess,cross are wehting proeess. Based on the different forms of coupling,these welding teehnologies are classified to three categories：a total of workpiece end arc welding proeess,a total of torch end are welding process and cross arc welding process. And makes expectation of the development trend of multi-lectrode arc welding technology.
