What are the special technical indicators of welding robots?

1) Applicable welding or cutting method This is particularly important for arc welding robots. This essentially reflects the anti-interference ability of the robot control and drive system. At present, general arc welding robots only use the MIG welding method, because these welding methods do not need to use high-frequency arc ignition, and the control and drive system of the welding robot does not have special anti-interference measures, and tungsten arc welding can be used. The welding robot is a new product in recent years, and it has a set of special anti-interference measures. Pay attention to this when choosing a robot.

2) Swing function This is very important for arc welding robots, and it is related to the process performance of arc welding robots. Currently, the swing function of arc welding robots is very different. Some robots have only several fixed swing modes, and some robots can only set swing modes and parameters arbitrarily on the plane. The choice is to be able to move in space (xy, z). Set the swing mode and parameters arbitrarily within this range.

3) Welding user point teaching function This is a very useful function in welding teaching, that is, when welding teaching, first teach the position of a certain point on the weld, and then adjust the posture of the welding gun or welding clamp. When adjusting the posture, the position of the original teaching point is completely unchanged. In fact, the robot can automatically compensate for the change in the position of the home point caused by the adjustment of the posture, and ensure the coordinates of the home point to facilitate the teaching of the operator.

4) Self-checking and self-processing functions for welding process faults. This refers to the common faults in the welding process, such as sticky wire in arc welding, broken wire, sticky electrode in spot welding, etc. After these failures, if measures are not taken in time, it will cause major accidents such as robot damage. Or scrap parts appear. Therefore, the welding robot must have the function of detecting such failures and automatically stopping and alarming in real time.

5) Arc ignition and arc closing functions need to change parameters in order to ensure welding quality. In robot welding, it should be able to be set and modified during the teaching process, which is an indispensable function of arc welding robots.
