Abstract
A joining method for forming a joint structure of different materials includes steps of: providing a steel member and a light metal member stacked on each other and to be joined together by friction stir welding in a non-melted state; applying a coating to the steel member; and joining the steel member and the light metal member together by rotatingly pushing a rotation tool into a joint portion of the light metal member with the steel member, generating friction heat and having the joint portion of the light metal member softened and plastically flow under the friction heat.
