摘要: A learning device includes: a data acquisition unit configured to acquire information on a welding condition when beads are deposited, a dimension related to a narrow portion forming a valley portion in a surface shape of an additively manufactured object before the beads are deposited, a positional relation between the narrow portion and a target position of the bead, and a defect size of an unwelded defect; and a learning unit configured to generate the estimation model by learning a relation between the welding condition, the dimension related to the narrow portion and the positional relation, and the defect size, and the dimension related to the narrow portion includes at least one of a bottom width of the valley portion, an opening width representing an interval between top portions on both sides of the valley portion, both sides constituting the valley portion, and a valley depth from the top portion to a bottom of the valley portion.

摘要: Disclosed example travel speed pacing systems for welding-type operations include: an interface configured to receive an input describing a characteristic of a welding-type operation; and control circuitry configured to: determine a target travel speed based on the input; determine a target time interval at which the welding-type operation is to traverse locations corresponding to successive ones of a plurality of marked locations on the workpiece of the welding-type operation, the target time interval being based on the target travel speed and a unit distance between the marked locations; and control the interface to output indicators representative of a target time interval.

摘要: Um bei einem Mehrfach-Lichtbogenfügeverfahren die Herstellung von geschuppten Nahtbildern zu ermöglichen, ist vorgesehen, dass in jedem Lichtbogenfügeprozess zumindest ein Fügeparameter (FPa, FPb), der eine von der Drahtvorschubgeschwindigkeit (v Da , v Db ) und dem Fügedraht (5a, 5b) abhängige Abschmelzleistung A des Lichtbogenfügeprozesses beeinflusst, mit einer periodischen Variationsfunktion (V a , V b ) mit einer Variationsfrequenz (fv) variiert wird, sodass in Folge dieses Variierens in jedem Lichtbogenfügeprozess der vorgegebene zeitliche Verlauf der Drahtvorschubgeschwindigkeit (v Da , v Db ) und der vorgegebene zeitliche Verlauf des Fügestromes (I Fa , I Fb ) in Abhängigkeit von der Variationsfunktion (V a , V b ) periodisch variiert wird.

摘要: An alternating current (AC) welding waveform, with two or more polarity changes during each molten metal droplet transfer cycle, is produced. The consumable welding electrode speed is mechanically controlled and the polarity is linked to known information about the electrode speed/direction, ensuring that at least two polarity changes are achieved per droplet transfer cycle. The arc polarity is concurrent with the change in direction of the electrode motion. The polarity can be changed based upon an actual speed of the electrode. Controlling the electrode motion and polarity in this way allows larger droplets to be created and higher deposition rates to be achieved at a lower frequency of shorting. The lower frequency of shorting also reduces wire feeder motor heating and wear, and increases contact tip life.
