Abstract

PURPOSE:To even the temperature distribution in the fixed region of the work and improve heating efficiency by relatively moving the work with respect to a heating beam and so controlling the radiation pattern formed on the work as to limit or omit part of the radiation as specified. CONSTITUTION:The apparatus consists of a laser oscillation device 11 as a heating beam feeder, an optical system 12, a control position former 13, transferring mechanism 14, etc. A laser beam 18 is sent out from the device 11, it is converted to a square laser beam 19 by the forming device 20 of the optical system 12, the beam 22 is focused by a focusing lens 23 by bending the optical path 19a at a right angle by a reflecting mirror 21 and a radiation pattern 7a is formed on the work 2 which is relatively moved in the arrow direction by a transfer table 25. At this time, a notch 24 is provided to the reflecting mirror 21 to control the radiation pattern 7a so as to omit part of the laser beam 19, whereby heating is done. As a result of this, the temperature distribution of the work 2 may be evenly controlled and heating efficiency considerably improved.
