    摘要: An arc welding control method for repeating alternately a short circuit period allowing a welding wire to short circuit with respect to a member to be welded and an arc period allowing arc recurrence and arc discharge to thereby weld the member to be welded, in which a welding output current just after arc recurrence is controlled to be higher than a welding output current just before arc recurrence for a set given period.

    摘要: A control method for an arc welding apparatus having a function of prohibiting detection of neck based on a change amount of welding voltage and an arc welding apparatus using the method. Thus, since neck determination can be carried out accurately by preventing wrong detection of neck, it is possible to reduce the occurrence of spatter.

    摘要: A welding control unit has a common power section for detecting contact of a welding material and for welding. A material contact detector for detecting contact of the welding material and a workpiece, and a power controller are built in the welding control unit. This stabilizes a bead shape in starting welding. The number of components can also be reduced, resulting in more inexpensive equipment. In addition, only a space for installing the welding control unit is needed without any additional space.

    摘要: Inputs output beams of a laser that have been oscillation-frequency modulated by an injection current control by a power source into a beam splitter through a lens and an isolator, detects beams reflected from a first half-mirror and passing through a path, beams reflected from a second half-mirror and passing through a path, and beams reflected from an object to be measured and passing through a path, with a photodetector, detects a beat frequency signal according to an optical interference of the above-described three types of reflected beams with a frequency detector, and calculates a distance to the object to be measured from the three beat frequencies with a signal processing unit. Can measure the distance in high precision by erasing a change rate of the oscillation frequency modulation and speed of light and by eliminating an influence of fluctuations, based on information of the three frequencies. Also, includes means using a lens for carrying out reflection and transmission on both sides of the lens instead of using the first and second mirrors and includes means using a polarization splitter and a 1/4 wave plate instead of using the beam splitter.
