Beschreibung
Zusammenfassung:	The invention provides a rapid and low-temperature local stress relaxation method for an aluminum alloy weld joint, relates to a local stress relaxation method for an aluminum alloy weld joint and aims to solve the problems that an existing method for eliminating residual stress of an aluminum alloy weld joint requires higher treatment temperature and long treatment time. The method comprises steps as follows: 1, parameters of an induction heating device are set: an induction coil of the induction heating device comprises a magnetizer and a red copper coil which are bonded with high-temperature-resistant insulating gel, the outer surface of the induction coil is wrapped with a glass fiber tape, the glass fiber tape is bonded with insulation varnish, joints are filled and finally, drying is performed; 2, the aluminum alloy weld joint is subjected to weld joint local stress relaxation through the induction heating device. The method can be used for local induction heating treatment, stress relaxation can be per
