1）適用的焊接或切割方法這對于弧焊機器人特別重要。這實質上反映了機器人控制和驅動系統的抗干擾能力。目前，一般的弧焊機器人只使用MIG焊接方法，因為這些焊接方法不需要使用高頻電弧點火，焊接機器人的控制和驅動系統沒有特殊的抗干擾措施，可以使用鎢極氬弧焊焊接。該焊接機器人是近年來的新產品，它具有一套特殊的抗干擾措施。選擇機器人時應注意這一點。

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）擺動功能這對于弧焊機器人非常重要，它與弧焊機器人的工藝性能有關。目前，電弧焊機器人的擺動功能已經非常不同。有些機器人只有幾種固定的擺動模式，有些機器人只能在平面上任意設置擺動模式和參數。選擇是能夠在空間（xy，z）中移動。在該范圍內任意設置擺動模式和參數。

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）焊接用戶點示教功能這是在焊接示教中非常有用的功能，即在進行焊接示教時，示教焊縫上某個點的位置，然后調節焊槍或焊鉗的姿勢。調整姿勢時，原始示教點的位置完全不變。實際上，機器人可以自動補償由于姿勢的調整而導致的住家點的位置變化，并確保住家點的坐標以方便教學操作者。

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）焊接過程故障的自檢和自處理功能。這是指焊接過程中常見的故障，例如電弧焊的粘絲，斷絲，點焊的粘焊條等。這些故障發生后，如果不及時采取措施，將會造成機器人損壞等重大事故?；虺霈F報廢零件。因此，焊接機器人須具有檢測此類故障并自動實時停止和報警的功能。

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）電弧點火和電弧閉合功能為了確保焊接質量，需要更改參數。在機器人焊接中，它應該能夠在教學過程中進行設置和修改，這是弧焊機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.
