Abstract
A welding power source is configured to supply a welding current to a wire as a consumable electrode. The welding power source includes a controller configured to change the welding current based on a position of a distal end of the wire a distance from which to a surface of a base metal varies periodically, in a case where the distal end of the wire is fed toward the base metal with periodical switching between a forward feeding period and a reverse feeding period.
Claims16
A welding power source configured to supply a welding current to a wire as a consumable electrode, the welding power source comprising:
- a controller configured to change the welding current based on a position of a distal end of the wire a distance from which to a surface of a base metal varies periodically, in a case where the distal end of the wire is fed toward the base metal with periodical switching between a forward feeding period and a reverse feeding period, wherein
- the controller is further configured to determine the position of the distal end of the wire based on a command value of a feeding speed of the wire.
A welding system configured to supply a welding current to a wire as a consumable electrode to perform arc welding, the welding system comprising:
- a controller configured to change the welding current based on a position of a distal end of the wire a distance from which to a surface of a base metal varies periodically, in a case where the distal end of the wire is fed toward the base metal with periodic switching between a forward feeding period and a reverse feeding period, wherein
- the controller is further configured to determine the position of the distal end of the wire based on a command value of a feeding speed of the wire.
A method for controlling a welding power source configured to supply a welding current to a wire as a consumable electrode, the method comprising:
- changing the welding current based on a position of a distal end of the wire a distance from which to a surface of a base metal varies periodically, in a case where the distal end of the wire is fed toward the base metal with periodic switching between a forward feeding period and a reverse feeding period, wherein
- the method further comprises determining the position of the distal end of the wire based on a command value of a feeding speed of the wire.
A computer program product comprising a non-transitory computer readable storage medium having instructions encoded thereon that, when executed by a computer in a welding system configured to supply a welding current to a wire as a consumable electrode to perform arc welding, causes the computer to perform an operation of:
- changing the welding current based on a position of a distal end of the wire a distance from which to a surface of a base metal varies periodically, in a case where the distal end of the wire is fed toward the base metal with periodic switching between a forward feeding period and a reverse feeding period, and
- determining the position of the distal end of the wire based on a command value of a feeding speed of the wire.
