Arc welding robots often use gas shielded welding methods (MAG, MIG, TIG), and commonly used welding power sources such as thyristor type, inverter type, waveform control type, pulse or non pulse type can be installed on the robot for arc welding. Due to the use of digital control in the robot control cabinet and the fact that welding power sources are mostly analog controlled, it is necessary to add an interface between the welding power source and the control cabinet.
In recent years, foreign robot manufacturers have their own specific supporting welding equipment, and corresponding interface boards have been inserted into these welding equipment, so there is no additional interface box in the arc welding robot system. It should be pointed out that in the working cycle of arc welding robots, the proportion of arc time is relatively large. Therefore, when selecting a welding power source, the capacity of the power source should generally be determined based on a duration rate of 100%.
The wire feeding mechanism can be installed on the upper arm of the robot or outside the robot. The hose between the welding gun and the wire feeding machine is shorter, which is conducive to maintaining the stability of wire feeding. The hose principal of the latter, when the robot sends the welding gun to certain positions, causing the hose to be in a multi bending state, will seriously affect the quality of wire feeding. Therefore, the installation method of the wire feeding machine must consider ensuring the stability of wire feeding.
Due to the use of integrated welding tongs, the welding transformer is installed behind the welding tongs, so the transformer of the spot welding robot must be minimized as much as possible. For transformers with smaller capacity, 50Hz power frequency AC can be used, while for transformers with larger capacity, inverter technology has been adopted in industry to convert 50Hz power frequency AC to 600-700Hz AC, reducing and reducing the volume of the transformer.
