JOINING METHOD AND JOINING COMPONENT

摘要

In joining members to be joined (1, 1) by heating the members to be joined (1, 1) that are mated with intervening an insert (2) while applying opposing loads to the members to be joined (1, 1), so as to allow eutectic reaction to occur between the members to be joined (1, 1) and the insert (2) to discharge a eutectic melt from a joining plane along with an oxide film (1a) of the members to be joined, the members to be joined (1) are brought into contact with the insert (2) so that the oxide film (1a) is broken by a stress concentrating means previously provided at least one of joining portions breaks to produce a starting point of the eutectic reaction.
