Abstract
A method and system of velocity control for an automatic welding apparatus, wherein at least either a welding torch or a workpiece is movable in the directions of the three rectangular axes and point-to-point (PTP) position control of the torch and workpiece is effected between two preset positions at a preset relative velocity. In effecting the PTP position control, the direction of movement is determined based on information about the two preset positions, and the components of the preset velocity in the directions of the three rectangular axes are determined based on the direction of movement thus found and also based on information about the preset velocity, these components being used as instruction velocities in the respective axes.
