Abstract
A joint processing method includes: a friction stir welding step for forming a joint in a plate by friction stir welding a groove in the plate; a cold working step for cold working the joint under cold working conditions such that a grain size in the joint is not more than a grain size of an aluminum alloy in the groove prior to the friction stir welding step; and a solution heat treatment step for, subsequent to the cold working step, performing solution heat treatment of the plate.
