ELECTRICALLY FUSION-BONDED JOINT.

摘要

An electrically fusion-bonded joint includes a body proper and is provided with a heater including a magnetic alloy piece having a fixed degree of Curie temperature at a portion in the vicinity of the body proper surface to be bonded so that the surface of the heater is exposed outside from the body proper surface to be bonded. When the body proper surface to be bonded is brought into contact with the surface of a member to be bonded and high frequency current is supplied to the magnetic alloy piece by electric induction, the magnetic alloy piece generates heat and the temperature thereof is kept at a fixed degree of Curie temperature by temperature self-control function thereof. Accordingly, when a Curie temperature is set at a degree for fusion-bonding, the body proper surface and the member to be bonded are fusion-bonded.
