Title:
摩擦接合方法
Document Type and Number:
Japanese Patent JP6500317
Kind Code:
B2
Abstract:
Provided are a simple and effective friction welding method that can suppress increases in hardness of the welded part and reductions in hardness (strength) in the heat affected zone regardless of the composition of ferrous material, and a welded structure obtained with the same. The present invention relates to a friction welding method wherein surfaces to be welded of two metal members (2, 4) to be welded are made to slide in contact with each other. The friction welding method is characterized in that at least one of the metal members (2, 4) to be welded is a ferrous material, and the maximum temperature reached during welding is equal to or less than the A 3 point or equal to or less than the A cm point of the ferrous material. The maximum temperature reached during welding is preferably equal to or less than the A1 point of the ferrous material.
