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.
