Abstract
In the automotive industry, aluminum alloy has been recently used to reduce vehicle weight of the vehicle body. Due to the high electrical and thermal conductivities and low melting point of aluminum alloy, however, it is not easy to achieve a high quality of welding. This paper has analyzed the changes in wire melting rate, arc melting phenomenon, and drop size with electrode negative (EN) ratio by applying AC pulse gas metal arc welding to the aluminum alloy sheet welding process. Furthermore, the characteristics of gap bridging have been analyzed and improved from the point of arc melting phenomenon by changing the EN ratio and gap in the welded joint.
