Simultaneously, tube 1 is swelled outward by deforming and forced to push the hole surface of tube plate 2, thereby completing vacuum sealing. Then, the inflate sealing member 2 is outwardly inflated by high-compressed air and the vacuum sealing is completed. Next, electron gun 4 is adjusted so as to allow an electron beam to strike the welding line between tube 1 and tube plate 2.

Based on a detection signal S3 from a limit switch (not shown), the control means 5 sends out in order a rotation command signal S4 to the rotating means 3 and an operation command signal S5 to the demagnetizing means 1 and demagnetization is started. Based on a time passage signal S6 from a timer (e), the control means 5 sends out a move-away command signal S7 to the moving means 2 and causes the demagnetizing means 1 to move back to its initial position. Based on a detection signal from a limit switch, the control means 5 sends out stop command signals S9, S10 to the demagnetizing means 1 and rotating means 3 respectively, and a series of demagnetization cycle is completed.
