A welding robot consists of a robot and welding equipment. The robot itself comprises a robot body and a control cabinet. Different types of welding robots can be selected based on the workpiece to be welded. Common welding robots include spot welding robots and arc welding robots. So, what are the differences between the two?
The difference between spot welding robots and arc welding robots:
Spot welding robots and arc welding robots are the most common types of robots in the automated welding market. They can play a significant role in production lines. Each type of welding robot has its own characteristics, different welding processes, and different requirements for the workpieces it can weld.
1. Differences in application scope
Arc welding robots can be applied in the fields of automobile manufacturing, general machinery, hardware and building materials, and fitness equipment. Spot welding robots are commonly used in automobile production workshops for accurate welding and can be used to form spot welding robot production lines, thereby improving production line efficiency.
2. Differences in welding precision requirements
The programming of arc welding robots is relatively complex, requiring precise control of the welding torch posture and trajectory. During programming, the trajectory should closely approximate the taught trajectory and should also include software functionality for different oscillation patterns, allowing selection during programming for oscillation welding. Spot welding robots, on the other hand, primarily focus on the positioning of the point and the workpiece, with less stringent requirements for the motion trajectory.
3. Differences in product features
Arc welding robots typically employ a six-axis structure in production. For welding large workpieces, guide rails or floor rails can be added, with the load capacity selected based on the robot model. Spot welding robots primarily use electric servo drives, allowing for the selection of appropriate welding guns according to the workpiece's load, and they have a larger lifting capacity.
