ABSTRACT:
A light beam heating system is suited for use in performing local heating. The light beam heating system includes a light source for emitting light, an optical lens assembly for converging the light emitted from the light source on an object to be heated, and a gas cylinder for supplying shielding gas towards the object via a gas regulator, a gas valve, and a gas nozzle. During heating, the oxygen concentration of an atmosphere around the object is maintained to less than 5%. Preferably, the shielding gas is supplied to the object via a temperature regulator so that the shielding gas may be heated to a desired temperature prior to the heating of the object.
