Provided is a welding program production system that can increase efficiency of a welding operation by a welding robot. The welding program production system includes a display control unit that causes a plurality of candidate welding lines detected on the basis of an image of a photographed object to be welded to be displayed in superimposed relation on the image, an input receiving unit that receives an input to select the welding lines from among the plurality of candidate welding lines and an input to specify a welding order and a welding direction for each of the selected welding lines, and a program production unit that produces a welding program on the basis of the specified welding order and welding direction.

Welding program production system and welding program production method

An arc start adjustment device adjusting an arc start procedure in a welding process comprises an obtainment unit that obtains welding data indicating a welding state during or after a welding process, and a procedure adjustment unit that adjusts the arc start procedure such that the cycle time of the welding process is shortened based on welding data obtained by the obtainment unit.

A work program production system includes a photographing unit that photographs an image including an object to be welded, a coordinate system setting unit that sets a user coordinate system based on a marker included in the image photographed by the photographing unit, a point-group-data plotting unit that detects a specific position of the marker on the basis of the image, sets the detected specific position on point group data acquired by a distance measurement sensor that measures a distance to the object to be welded, and plots, in the user coordinate system, the point group data to which coordinates in the user coordinate system using the set specific position as an origin are given, and a program production unit that produces a welding program.

A control method for AC pulse arc welding performed upon application of cyclic AC welding current is provided. The welding current has a cycle including an electrode negative polarity period and an electrode positive polarity period subsequent to the electrode negative polarity period. In the control method, an electrode negative polarity base current and a subsequent electrode negative polarity peak current are applied during the electrode negative polarity period. The electrode negative polarity base current has an absolute value smaller than a first critical value, and the electrode negative polarity peak current has an absolute value greater than the first critical value. Then, an electrode positive polarity peak current is applied during the electrode positive polarity period. The electrode positive polarity peak current has a value greater than a second critical value.
