The corrugated section welding process null in the arc welding robot for the corrugated doubler patch

摘要

PURPOSE: To obtain good weld beads by adding parameters to arbitrarily change a welding speed and welding torch angle to the corrugation shape to be previously inputted as an NC parameter and controlling both at the time of welding by a delayed control system to precede a sensor to a welding robot. ;CONSTITUTION: The torch angle is gradually changed within a range of the determined Mx. angle from just before the welding torch arrives at the round parts in the skirt parts 20, 21 of corrugations where the angle of the weld zone changes sharply, by which the change in the torch angle in the round parts is smoothed. The welding speed is increased to lower the heat input to a weld line in the round parts of the skirt parts 20, 21 of the corrugations where the radius of curvature is small and the diffusion of heat with respect to the weld length is smaller than in the plane parts and the round parts of the peak parts 22 of the corrugation shape where the concentration of the heat is liable to arise as the welding torch moves while facing the same point.;COPYRIGHT: (C)1996,JPO
