1) Applicable welding or cutting methods, which are 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 molten gas shielded welding methods, because these welding methods do not need to use high-frequency arc welding, and the robot control and drive system do not have special anti-interference measures. The arc welding robots that can use tungsten argon arc welding are For new products in recent years, it has a set of special anti-interference measures. This should be paid attention to when choosing a robot.
2) Swing function, which is very important for arc welding robot, it is related to the process performance of arc welding robot. At present, the swing function of arc welding robots is very different. Some robots only have several fixed swing modes, and some robots can only set swing modes and parameters arbitrarily in the xy plane. The best choice is to set the swing mode and parameters in the space (xy, z ) Set swing mode and parameters arbitrarily within the range.
3) Welding user point teaching function This is a very useful function during welding teaching, that is, when welding teaching, first teach the position of a certain point on the weld, and then adjust the welding gun or welding clamp posture. When adjusting the posture, the position of the original teaching point is completely unchanged. In fact, the robot can automatically compensate for the changes in the position of the household point caused by the adjustment of the posture, and ensure the coordinate of the household point to facilitate the teaching operator.
4) Welding process fault self-checking and self-processing functions, which refer to common welding process faults, such as sticking wire in arc welding, broken wire, sticking in spot welding, etc. After these faults occur, if measures are not taken in time, Major accidents such as damage to the robot or scrapped parts may occur. Therefore, the robot must have the function of detecting such failures and automatically stopping and alarming in real time.
5) Arc ignition and arc closing functions To ensure welding quality, parameters need to be changed. In robot welding, it should be able to set and modify during teaching, which is an indispensable function of arc welding robot.
