焊接機器人應用于機械制造產業，其中在汽車制造業應用的較為普遍。焊接機器人的控制系統可以實現自動焊接，智能控制系統就和人的大腦一樣，可以下達指令來完成一系列的操作，控制系統可以對焊縫智能識別，根據焊縫的規格做出反應，選擇合適的焊接參數相匹配，保證焊接的穩定性。那么，怎樣選擇合適的焊接機器人呢？
Welding robots are used in mechanical manufacturing industry, especially in automobile manufacturing industry. The control system of the welding robot can realize automatic welding. The intelligent control system, just like the human brain, can issue instructions to complete a series of operations. The control system can intelligently identify the weld, react according to the weld specifications, select appropriate welding parameters to match, and ensure the stability of welding. So, how to choose the right welding robot?
1.機器人通用技術指標
General technical indicators of robot
①判斷焊接機器人靈活性的重要指標是自由度數。一般而言，在機器人工作空間中可以到達3個自由度，但是焊接不僅必須到達空間中的某個位置，而且還必須確保焊槍的空間姿勢。因此，電弧焊和切割機器人至少需要5個自由度，點焊機器人至少需要6個自由度。
The degree of freedom is an important index to judge the flexibility of welding robot. Generally speaking, three degrees of freedom can be reached in the robot workspace, but welding must not only reach a certain position in the space, but also ensure the spatial posture of the welding gun. Therefore, arc welding and cutting robots need at least 5 degrees of freedom, and spot welding robots need at least 6 degrees of freedom.
②負載是指機器人末端可以承受的額定負載。焊槍及其電纜，切割工具和煤氣管，焊鉗和電纜以及冷卻水管都是負載。因此，電弧焊和切割機器人的負載能力為6-10kg。如果點焊機器人使用集成變壓器和集成焊鉗，則其負載能力應為6090kg。如果使用單獨的焊鉗，其負載能力應為4050kg。
The load refers to the rated load that the robot end can bear. The welding gun and its cables, cutting tools and gas pipes, welding tongs and cables, and cooling water pipes are all loads. Therefore, the load capacity of arc welding and cutting robots is 6-10kg. If the spot welding robot uses integrated transformer and integrated welding tongs, its load capacity shall be 6090kg. If a separate welding tongs is used, its load capacity shall be 4050kg.
工作空間制造商給定的工作空間是機器人在沒有任何終端操縱器的情況下可達到的最大空間，該空間由圖形表示。安裝焊炬后，應特別注意焊炬的姿勢。實際可焊接空間將比制造商提供的空間小一層。有必要用比例圖法或模型法仔細計算以確定其是否滿足實際需要。
Workspace The workspace given by the manufacturer is the maximum space that the robot can reach without any terminal manipulator, and this space is represented by a graph. After installing the torch, pay special attention to the position of the torch. The actual weldable space will be one floor less than the space provided by the manufacturer. It is necessary to calculate carefully with scale drawing method or model method to determine whether it meets the actual needs.
2.焊接機器人的特殊技術指標
Special technical indicators of welding robot
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，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。
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. At present, the general arc welding robot only uses MIG welding methods, because these welding methods do not need to use high-frequency arc ignition, and the robot control and drive system has no special anti-interference measures, and can use argon tungsten arc welding. The robot is a new product in recent years, which has a set of special anti-interference measures. This should be noted when selecting robots.
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xy平面上任意設置擺動模式和參數。最佳選擇是能夠在空間中移動。在該范圍內任意設置擺動模式和參數。
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 robots can only set swing modes and parameters arbitrarily on the xy plane. The best choice is to be able to move in space. Set the swing mode and parameters arbitrarily within 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，首先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。
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 is completely unchanged. In fact, the robot can automatically compensate the position change of the home point caused by the posture adjustment, and ensure the coordinates of the home point to facilitate the teaching operator.
