The arc welding process of the welding robot is much more complicated than the spot welding process. The tool center point, the arc welding robot FANUC M-10iA, that is, the motion trajectory of the welding wire end, the welding gun posture, and the welding parameters require precise control. Therefore, in addition to the general functions described above, the arc welding robot must also have some functions suitable for arc welding requirements. Although theoretically speaking, a robot with 5 axes can be used for arc welding, but it is difficult to use a robot with 5 axes for complicated welds. Therefore, unless the weld is relatively simple, a 6-axis robot should be used as much as possible.
In addition to the previously mentioned arc welding robot for zigzag corner welding or small diameter round weld welding, its trajectory should be close to the taught trajectory, and it should also have software functions for different swing patterns for programming.
It is selected to be used for weaving welding, and the robot should automatically stop moving forward at the stopping point in each cycle to meet the technological requirements. In addition, there should be contact location, automatic search for the starting point of the weld, arc tracking and automatic arc re-ignition functions.
