Arc welding characteristics of welding robots

The arc welding process is much more complicated than the spot welding process. The tool center point (TCP), that is, the movement trajectory of the wire end, the welding gun posture, and the welding parameters all require precise control. Therefore, in addition to the general functions mentioned above, arc welding robots must also have some functions suitable for arc welding requirements.
Although theoretically, a robot with 5 axes can be used for arc welding, it is difficult to use a robot with 5 axes for welds with complex shapes. Therefore, unless the weld is relatively simple, a 6-axis robot should be used as much as possible.
In addition to the trajectory of the arc welding robot being able to be close to the taught trajectory when performing "Z"-shaped corner welding or small-diameter circular weld welding, it should also have software functions with different swing styles for selection during programming, so as to perform swing welding, and the robot should automatically stop moving forward at the pause point in each cycle of the swing to meet the process requirements. In addition, it should also have contact positioning, automatic search for the starting position of the weld, arc tracking, and automatic re-arcing functions.
