Filed: 1988-08-26
Abstract: PURPOSE:To prevent the addition of impurities into a weld metal and to execute laser welding of Al materials having high-strength weld zones by using Al (alloy) of a high b. p. and low Mg content, shielding the same with an inert gas and increasing the power density of a laser beam until melting arises on the surfaces of base materials. CONSTITUTION:The laser beam 3 released from an oscillator 1 via a window 2 is condensed to a required power density by a condenser lens 4. The inert gas such as gaseous Ar is introduced 7 as the shielding gas prior to irradiation of the beam. A member 6 for welding consisting of the Al material is then irradiated with the beam 3 to form weld beads 8. The welding is ended in a prescribed position. The inert gas which does not react with the Al is used as the shielding gas during this time and the power density of the laser beam to be applied to the surface of the member 6 is set to a prescribed value or above without previously subjecting the member to a special surface treatment. The Al material is melted in this way and the weld zone having sufficient welded joint efficiency and high quality is obtd. without allowing the impurities to intrude into the weld metal.

Filed: 1989-08-18
Abstract: PURPOSE:To send an optical signal economically with less power by providing a voltage comparator between a drive circuit and a photodetector circuit and controlling a level of an optical signal sent from a light emitting element in response to an optical reception level. CONSTITUTION:A voltage comparator 9 provided between a drive circuit 1 and a photodetector circuit 8 supplies a control signal to the circuit 1 so that the level of an optical signal from the circuit 8 is decreased when the optical reception signal sent from a light emitting element 2 is higher than a reference voltage VR. Since the output level of the optical signal in the outgoing direction is reduced, the output level of the incoming optical signal is also decreased via an optical reception circuit 4 and a drive circuit 5 and the output level is entirely made stable. When the optical reception level from the circuit 8 is lower than the voltage VR, the comparator applies the reverse operation to above. That is, the comparator 9 generates a control voltage so as to make the output level of the incoming optical signal is inversely proportional to the voltage VR and controls the outgoing optical signal output level to attain economical transmission of the optical signal with less power.
