Gas maintenance welding methods (MAG, MIG, TIG) are commonly used in arc welding robots. Generally, controllable silicon type, inverter power supply type, waveform control type, single pulse or single pulse type welding switch power supplies can be placed in the robot for arc welding. Because the intelligent robot control box uses computer control, and the welding switch power supply is often simulated and manipulated, it is necessary to add a socket between the welding switch power supply and the control box.
In recent years, intelligent robot manufacturers often have their own special supporting facilities, automatic welding machines, which have already been equipped with corresponding interface boards. Therefore, there is no additional socket box in the arc welding robot system. It should be emphasized that the proportion of arc time in the cycle time of arc welding robots is large. Therefore, when selecting a welding switch power supply, the volume of the switch power supply should generally be determined based on a continuous rate of 100%.
The wire feeding organization can be installed on the upper arm of the intelligent robot, and can also be placed outside the intelligent robot. The plastic hose between the welding machine and the wire feeding machine in the front is relatively short, which is beneficial for maintaining the reliability of wire feeding, while the plastic hose in the back is calibrated. When the intelligent robot sends the welding machine to some parts, causing the plastic hose to be in multiple bends, it will seriously endanger the quality of wire feeding. Therefore, the installation method of the wire feeder must take into account the difficulty of ensuring the reliability of wire feeding.
