1）适用的焊接或切割方法这对于弧焊机器人特别重要。这实质上反映了机器人控制和驱动系统的抗干扰能力。目前，一般的弧焊机器人只使用MIG焊接方法，因为这些焊接方法不需要使用高频电弧点火，焊接机器人的控制和驱动系统没有特殊的抗干扰措施，可以使用钨极氩弧焊焊接。该焊接机器人是近年来的新产品，它具有一套特殊的抗干扰措施。选择机器人时应注意这一点。

1) Suitable welding or cutting method, which is particularly important for arc welding robot. This essentially reflects the anti-interference ability of robot control and drive system. At present, the general welding robot only uses MIG welding method, because these welding methods do not need to use high-frequency arc ignition, the control and drive system of welding robot has no special anti-interference measures, and can use TIG welding. The welding robot is a new product in recent years, it has a set of special anti-interference measures. This should be noted when choosing a robot.

2）摆动功能这对于弧焊机器人非常重要，它与弧焊机器人的工艺性能有关。目前，电弧焊机器人的摆动功能已经非常不同。有些机器人只有几种固定的摆动模式，有些机器人只能在平面上任意设置摆动模式和参数。选择是能够在空间（xy，z）中移动。在该范围内任意设置摆动模式和参数。

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

3）焊接用户点示教功能这是在焊接示教中非常有用的功能，即在进行焊接示教时，示教焊缝上某个点的位置，然后调节焊枪或焊钳的姿势。调整姿势时，原始示教点的位置完全不变。实际上，机器人可以自动补偿由于姿势的调整而导致的住家点的位置变化，并确保住家点的坐标以方便教学操作者。

3) welding user point function, which is a very useful function in welding instruction, is to teach the location of a spot on the weld before carrying out the welding instruction, and then adjust the position of the welding torch or welding clamp. When the posture is adjusted, the position of the original teaching point is completely unchanged. In fact, the robot can automatically compensate for the change of the position of the home point caused by the adjustment of the posture, and ensure the coordinates of the home point for the convenience of the teaching operator.

4）焊接过程故障的自检和自处理功能。这是指焊接过程中常见的故障，例如电弧焊的粘丝，断丝，点焊的粘焊条等。这些故障发生后，如果不及时采取措施，将会造成机器人损坏等重大事故。或出现报废零件。因此，焊接机器人须具有检测此类故障并自动实时停止和报警的功能。

4) Self check and self-treatment function of welding process fault. This refers to the common faults in the welding process, such as wire sticking, broken wire in arc welding, welding rod sticking in spot welding, etc. After these failures occur, if no timely measures are taken, it will cause serious accidents such as robot damage. Or there are scrapped parts. Therefore, the welding robot must have the function of detecting such faults and automatically stopping and alarming in real time.

5）电弧点火和电弧闭合功能为了确保焊接质量，需要更改参数。在机器人焊接中，它应该能够在教学过程中进行设置和修改，这是弧焊机器人不可或缺的功能。

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