High Accuracy 6 Axis MIG Welding Manipulator for Welding Robot Production Line
Welding process requirements for mig welding manipulator
The welding robot can move the welding torch along the weld seam with high precision and ensure the attitude of the welding torch; continuously coordinate the welding process parameters (such as welding current, voltage, speed, gas flow rate, electrode height and wire feeding speed) during the movement.
The welding robot is a comprehensive system that can achieve the best process motion and parameter control of welding. It is much more complicated than a general - purpose robot.
MIg welding manipulator automated welding production types
The type of automated welding production that the factory chooses must be based on the actual conditions and merits of the plant. The welding special machine is suitable for large - volume, slow - changing products, and the number of welds of the workpiece is small and long, and the shape is regular (straight and round); the welding robot system is generally suitable for medium and small batch production, and the workpiece is welded. Welds can be short and many, and the shape is more complicated.
The welding robot production line is relatively simple to connect multiple workstations (units) with workpiece conveyor lines to form a production line. This line still maintains the characteristics of a single station, that is, each station can only use the selected workpiece fixture and welding robot program to weld the predetermined workpiece. This line cannot be welded for a period of time before the fixture and program are changed other artifacts.
