PURPOSE: A pulse welding method for reducing spatter using a current pattern change is provided to reduce welding defects by reducing spatter more than 10%. CONSTITUTION: A pulse welding method for reducing spatter using a current pattern change comprises a current pattern change. The current pattern change is composed of a base section, an ascent section, a peak section, and a descent section. In the base section, globules are separated from a supply wire and are fused with a globule member. In the ascent section, the fusion of the supply wire is started. In the peak section, the supply wire is fused until a globule is formed in the front end of the supply wire. In the descent section, the globule formed in the front end of the supply wire is separated from the supply wire.
