Beschreibung
Zusammenfassung:	A friction stir welding method for bonding a to-be bonded material, includes: a step of supplying nitrogen and introducing nitrogen into the to-be bonded material while melting the to-be bonded material; and a step of friction stir welding a portion of the non-bonded material in which the nitrogen is introduced. A friction stirring device for bonding a to-be bonded material, includes: a heating source for melting the to-be bonded material; a nitrogen supply source for supplying nitrogen to a melted portion of the to-be bonded material and introducing nitrogen into the to-be bonded material; and a friction stir tool for friction stir welding a portion of the non-bonded material in which the nitrogen is introduced.
