Welding robots mainly consist of two parts: the robot itself and the control cabinet (hardware and software). Welding equipment, such as arc welding and spot welding, is composed of welding power sources (including their control systems), wire feeders (for arc welding), welding clamps, and so on. For intelligent robots, a sensor system is also required, such as laser or camera sensors and their control devices.
If the workpiece does not require any movement throughout the welding process, it can be clamped and positioned on the workbench surface, making this system quite simple. However, in actual production, more workpieces need to be moved during welding to ensure the weld seam is in an optimal position (attitude). In such cases, the positioning machine and the robot can either move separately—meaning the positioning machine moves first, followed by the robot welding—or they can move simultaneously—meaning the positioning machine moves while the robot welds, which is commonly referred to as coordinated movement between the positioning machine and the robot. At this point, the combined movement of the positioning machine and the robot enables the welding to...ClampIn relation to the workpiece movement, it can meet both the welding path and the welding speed requirements.ClampRequirement for posture. In fact, at this point, the axis of the transposer has become a part of the robot. This welding robot system can have up to 7-20 axes, or even more.
The control cabinet for robots can coordinate the movement of 12 axes between two robots. One is a welding robot, and the other is a handling robot used for positioning machines.
