The difference between welding robot and special welding machine and the function of its external axis

自從自動化技術(shù)普及到焊接領(lǐng)域之后，出現(xiàn)了焊接機(jī)器人和焊接專機(jī)兩種常見的焊接系統(tǒng)，雖然它們都是專用的機(jī)械設(shè)備，但肯定還是存在一些差異性的。所以下面就要將焊接機(jī)器人與焊接專機(jī)進(jìn)行對比。

Since automation technology has been popularized to the welding field, there are two common welding systems, welding robot and welding machine. Although they are special mechanical equipment, there must be some differences. So the following will be welding robot and welding machine for comparison.

從方面來說，焊接專機(jī)要比焊接機(jī)器人更有優(yōu)勢，但大多數(shù)的廠家還是會選擇焊接機(jī)器人，因為焊接專機(jī)是針對某種特定的產(chǎn)品而研制出的自動化設(shè)備，多采用伺服X、Y、Z軸三個方，一般只是焊接圓形或是焊接直焊縫。

In terms of price, the special welding machine has more advantages than the welding robot, but most manufacturers will choose the welding robot, because the special welding machine is an automatic equipment developed for a specific product, which mostly uses servo x, y and Z axes, generally only welding round or straight welds.

而焊接機(jī)器人就不一樣了，它采用6個伺服控制，非常靈活，可以三維立體任何方向不規(guī)則的焊接，所以相對高一些。不過焊接專機(jī)可以配4到5個焊頭，效率比焊接機(jī)器人還要高。焊接機(jī)器人與焊接專機(jī)的不同及其外部軸的作用

The welding robot is not the same, it uses six servo control, very flexible, can three-dimensional irregular welding in any direction, so the price is relatively higher. However, the welding machine can be equipped with 4 to 5 welding heads, which is more efficient than the welding robot. The difference between welding robot and special welding machine and the function of its external axis

由此可見，若是平面上的直縫、圓縫的話要選擇焊接專機(jī)，但只要旦焊接產(chǎn)品變了規(guī)格或變了形狀，那焊接專機(jī)就無用武之地了。而焊接機(jī)器人正好彌補(bǔ)了這方面的不足，這種情況下只需要重新編個程序又可以再次使用了。

It can be seen that the welding machine should be selected for the straight and round seams on the plane, but as long as the welding product changes its specification or shape, the welding machine will be useless. The welding robot just makes up for this deficiency. In this case, it only needs to reprogram and can be used again.

隨著焊接機(jī)器人應(yīng)用范圍的擴(kuò)大，焊接機(jī)器人除了基本的配置外，有時候還會增加一個或多個外部軸。也就是說，外部軸其實就是一個跟焊接機(jī)器人相連的外部動作系統(tǒng)，來配合機(jī)器人的動作，能夠同時滿足焊接姿勢，也能更快速的完成整個焊接，達(dá)到滿意的效果。

With the expansion of welding robot application, in addition to the basic configuration, welding robot sometimes adds one or more external axes. In other words, the robot can complete the welding action quickly with the external axis.
