1) Suitable welding or cutting methods This is particularly important for arc welding robots. This essentially reflects the anti-interference ability of the robot control and drive system. Currently, general arc welding robots only use MIG welding methods, because these welding methods do not require the use of high-frequency arc ignition, and the robot's control and drive system does not have special anti-interference measures, so tungsten argon arc welding can be used. The robot is a new product in recent years, and it has a special set of anti-interference measures. This should be noted when selecting robots.
2) The swing function is very important for arc welding robots, which is related to the technological performance of the arc welding robot. Currently, the swing function of arc welding robots is very different. Some robots only have several fixed swing modes, and some robots can only arbitrarily set swing modes and parameters on the x and y planes. The best option is to be able to move in space (x, y, 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 teaching welding, first teach the position of a point on the weld, and then adjust the position of the welding gun or welding tongs. When adjusting the posture, the position of the original teaching point remains completely unchanged. In fact, the robot can automatically compensate for changes in the location of the home point caused by posture adjustments, and ensure the coordinates of the home point for the convenience of teaching operators.
4) Self inspection and self processing functions for welding process faults. This refers to common faults in the welding process, such as sticking and breaking wires in electric arc welding, and sticking electrodes in spot welding. After these failures occur, if measures are not taken in a timely manner, significant accidents such as robot damage will result. Or there are scrapped parts. Therefore, the robot must have the function of detecting such faults and automatically stopping and alarming in real time.
5) The arc ignition and arc closing functions require parameter changes to ensure welding quality. In robotic welding, it should be able to set and modify during the teaching process, which is an indispensable function of arc welding robots.
