摘要： A laser machining system includes a laser oscillator, a laser machining head, and a reflection unit. The laser oscillator outputs laser light. The laser machining head, which includes a first optical member for collecting the laser light, emits the collected laser light. The reflection unit, which includes a reflective member for reflecting the laser light emitted from the laser machining head, radiates the reflected laser light onto a work.

摘要： An arc-welding method in welding by repeating a short circuit and an arc. When the sign of opening of the short circuit is detected, the welding current is reduced from a first current value at the detection of the sign to a second current value, which is lower than the first current value. When the opening of the short circuit is detected, a pulse current having a peak value higher than the first current value is supplied at a plurality of times in the arc period. This suppresses porosities and spatters when galvanized steel sheets are welded.

摘要： Disclosed is a consumable electrode arc welding in which short-circuit welding is performed by alternating short-circuits and arcs while a welding wire is fed automatically. In this method, a short-circuit state and an arc state are alternately generated by feeding the welding wire in periodically alternating forward and backward directions at a predetermined frequency and a predetermined velocity amplitude with reference to a basic wire feed speed based on a set current. The speed of periodic feeding of the welding wire is controlled in such a manner that the waveform to feed the welding wire is different between the forward and backward directions.

摘要： In a consumable electrode-type arc welding in which pulse welding and short-circuit welding are alternately repeated, a welding current is controlled such that a welding current immediately before shifting from the pulse welding to the short-circuit welding is lower than a base current in a pulse.

摘要： The arc welding method of the present invention is a consumable electrode arc welding in which a welding wire feeding rate suitable for a welding current is determined as an average feeding rate, and the short circuit state and the arc generation state are alternately generated by changing the wire feeding periodically and repeatedly between the forward feeding and the reverse feeding. The method offers arc welding with the average feeding rate according to a welding current, a predetermined frequency, and a predetermined velocity amplitude. In the method, at least any one of the frequency and the velocity amplitude is set to a value suitable for the welding current.

摘要： In controlling an arc welding of consumable electrode type in which pulse welding and short-circuit welding alternately repeat, forward feeding and backward feeding of a welding electrode periodically repeat in a short-circuit welding period. The forward feeding of the welding electrode starts when a welding current is smaller than a base current immediately before a pulse period ends.

摘要： As a conventional problem, welding on surface-treated material, such as a zinc-coated steel plate, considerably generates air holes including blowholes and also generates lots of spatters. Present invention provides a method of controlling arc welding performed in a manner that a short-circuit period, in which a short circuit is generated between a welding wire and an object to be welded, and an arc period, in which an arc is generated after release of the short circuit, are repeated alternately. According to the method, welding current is increased from an arc-regeneration-before current to a first welding current at a detection of release of the short circuit such that an increase gradient of the welding current becomes not less than 750A/msec. This suppresses generation of air holes and spatters in welding work on a surface-treated material, such as a zinc-coated steel plate.
