、波形控制式、脈沖或非脈沖式等的焊接電源都可以裝到機(jī)器人工作電弧焊。由于機(jī)器人控制框采用數(shù)字控制，而焊接電源多為模擬控制，所以需要在焊接電源與控制柜之間加一個(gè)接口。

近年來(lái)國(guó)外機(jī)器人生產(chǎn)廠都有自己特定的配套焊接設(shè)備，這些焊接設(shè)備內(nèi)已經(jīng)插入相應(yīng)的接口板并附加接口箱

。在弧焊機(jī)器人工作周期中電弧時(shí)間所占的比例較大，因此在選擇焊接時(shí)，一般應(yīng)按持續(xù)率100%來(lái)確定電源的容量。

送絲機(jī)可以裝在機(jī)器人的上臂上

，也可以放在機(jī)器人之外，前者焊槍到送絲機(jī)之間的軟管較短，有利于保持送絲的穩(wěn)定性，面后者軟管較長(zhǎng)，當(dāng)機(jī)器人把焊槍送到某些位置，使軟管處于多彎曲狀態(tài)，會(huì)嚴(yán)重影響送絲的質(zhì)量。所以送絲機(jī)的安裝方式一定要考慮保證送絲穩(wěn)定性的問(wèn)題。

The arc welding process is much more complicated than the spot welding process. The tool point (TCP), that is, the trajectory of the wire tip, the torch attitude, and the welding parameters all require precise control. Therefore, in addition to the general function, the arc welding robot must also have some functions suitable for arc welding.

Although in theory, a robot with five axes can be used for arc welding, it is difficult to use a five-axis robot for a complex-shaped weld. Therefore, unless the weld is relatively simple, you should try to use a 6-axis robot.

When the arc welding robot is used for "Zigzag" or small diameter round weld welding, its trajectory should be close to the teaching trajectory. It should also have different swinging style software functions for programming. Welding, and swinging at the pause point in each cycle, the robot should also automatically stop moving forward to meet the process requirements. In addition, there should be contact locating, automatic search for the starting position of the weld, arc tracking and automatic re-arcing.

Arc welding robots mostly use gas shielded welding methods (MAG, MIG, TIG), and the usual welding power supplies such as thyristor, inverter, waveform control, pulse or non-pulse can be installed in the robot working arc welding. Since the robot control frame is digitally controlled, and the welding power source is mostly analog control, an interface needs to be added between the welding power source and the control cabinet.

In recent years, foreign robot manufacturers have their own specific matching welding equipment. These welding equipments have been inserted into the corresponding interface boards and attached to the interface box. In the arc welding robot working cycle, the arc time accounts for a large proportion. Therefore, when selecting the welding, the capacity of the power source should generally be determined according to the continuous rate of 100%.

The wire feeder can be mounted on the upper arm of the robot or outside the robot. The hose between the former and the wire feeder is shorter, which is beneficial to maintain the stability of the wire feeding. When the robot sends the torch to a certain position, the hose is in a multi-bend state, which seriously affects the quality of the wire feed. Therefore, the installation method of the wire feeder must consider the problem of ensuring the stability of the wire feed.
