Abstract
An arc welding device includes memory in which a combination of a short circuit frequency, a peak current, and a peak current period is stored and determinator that determines a peak current and a peak current period based on a set short circuit frequency and the combination stored in memory. A welding output part performs welding output based on the peak current and the peak current period determined by determinator.
Claims13
An arc welding device that welds an object to be welded by alternately repeating a short-circuit period in which a welding wire is short-circuited with the object to be welded and an arc period in which the short circuit is released and arc occurs, the object to be welded being a surface-treated steel plate, the arc welding device comprising:
- a welding output part that performs welding output;
- a memory storing one or more combinations associating in advance a peak current and a peak current period with a short circuit frequency that is a number of times of the short circuit per predetermined time so that discharge of gas generated from the object to be welded during welding is prompted;
- and
- a determinator that determines a peak current and a peak current period associated with a short circuit frequency set by a short circuit frequency setter based on the short circuit frequency set by the short circuit frequency setter and the one or more combinations stored in the memory,
- wherein the welding output part performs the welding output based on the peak current and the peak current period determined by the determinator, the welding output prompting discharge of gas generated from the object to be welded during welding.
(canceled)
An arc welding control method for welding an object to be welded by alternately repeating a short-circuit period in which a welding wire is short-circuited with the object to be welded and an arc period in which the short circuit is released and arc occurs, the object to be welded being a surface-treated steel plate, the arc welding control method comprising:
- setting a short circuit frequency that is a number of times of the short circuit per predetermined time;
- determining a peak current and a peak current period associated with the short circuit frequency set based on one or more combinations associating in advance a peak current and a peak current period with a short circuit frequency so that discharge of gas generated from the object to be welded during welding is prompted;
- and
- controlling welding output based on the peak current and the peak current period which are determined, the welding output prompting discharge of gas generated from the object to be welded during welding.
(canceled)
An arc welding device that welds an object to be welded by alternately repeating a short-circuit period in which a welding wire is short-circuited with the object to be welded and an arc period in which the short circuit is released and arc occurs, the object to be welded being a surface-treated steel plate, the arc welding device comprising:
- a welding output part that performs welding output;
- a memory storing one or more combinations associating in advance a waveform parameter with a short circuit frequency that is a number of times of the short circuit per predetermined time so that discharge of gas generated from the object to be welded during welding is prompted;
- and
- a waveform parameter determinator that determines a waveform parameter based on a short circuit frequency set by a short circuit frequency setter and the one or more combinations stored in the memory,
- wherein the welding output part performs the welding output based on the waveform parameter determined by the waveform parameter determinator;
- and
- wherein the short circuit frequency is determined in accordance with a welding speed so that the short circuit occurs at intervals of equal to or less than 0.5 mm on a welding line.
