Abstract

PURPOSE: To make the cracking to be hardly caused in the tube plate, and to obtain the high reliable brazed zone, by jutting the neighborhood of the hole of the tube plate outward with the plastic working, etc., and then, by inserting the tube into the hole, and by brazing the contact portion between the tube and the hole of the tube plate.
CONSTITUTION: The hole is punched in the tube plate 2, and the neighborhood of this hole is jutted out by the plastic working. According to this method, the neighborhood of the hole receives the work hardening and its strength is raised; the outside of the jutting portion is loaded with the residual compression stress 15W25 kg/mm2. The tube 1 is inserted through the hole in the jutting tube plate 2 and both are jointed by brazing work according to the high frequency heating; hereupon, the cracking is hardly caused in the tube plate 2, and the high reliable brazing can be obtained.
