Abstract

The arc behavior of cold metal transfer technology in welding process and its effect on the appearance of weld are studied in details

and the micro-mechanism is also analyzed. The welding parameters such as welding voltage

welding current

wire feed rate and so on is controlled through integrated precision system

the micro-behavior of the welding arc are researched

the perfect combination of metal transfer physical behavior and welding parameters is achieved

which provides the theoretical base for obtaining high quality joining and appearance of welds

and also meets the design and welding demand for thin sheet covering parts of body-in-white. It has very important theoretical and practical engineering application value for enrichment and development of MIG welding method.
