Abstract
The laser-arc hybrid welding permits to improve the property of the weld metal using the filler wire. However, the improvement of the property of the weld metal is not so effective if the filler metal is distributed uniformly in the weld metal. Therefore, the uniform distribution of filler wire in the weld metal is important. This study shows the influence of the welding parameters (welding direction, welding gap, wire feed rate) on the distribution of filler wire in the welding metal.
