A method for joining a first part formed of an aluminum material to a second part formed of a steel material by metal inert gas welding and cold metal transfer is provided. An aluminum filler material forms a fillet joint between the parts and provides a structure for automotive body applications, such an aluminum bumper extrusion joined to a steel crush box connection. The first part includes a notch for hiding the start and end of the joint. A transition plate formed of a mixture of aluminum material and steel material can be disposed between the first part and the second part to provide the notch. The second part can include a mechanical fastener further joining the parts together. In another embodiment, the second part includes a plurality of dimples and is welded to the first part along the dimples.
