Abstract

In this study, the effect of variation of intermittent wire feeding method on thermal histories during the welding process, the physical appearance, mechanical properties, and fracture mode was investigated. The configuration parameter of wire feeding was determined by the properties of the so-called length ratio (RL). It was influenced by welding speed, wire feeding speed, feeding time, and delaying time. Bigger value of length ratio tends to have a smaller bead width with a higher cap. Also, a larger ratio tends to have bigger tensile strength and the fracture location close to the weld bead.
