The implementation of Internet-of-Things (IoT) technology enables enhanced communication and data exchange between robotic welding systems, using absolute and relative position sensors to calculate and apply correction vectors for precise alignment of the welding torch along planned paths, even when deviations occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional robotic welding systems are used with limited communication capabilities, then system simplicity is maintained, but welding accuracy and control precision deteriorate due to inability to perform real-time corrections
Solution Approach 1:
The system continuously monitors the actual weld path using sensors and compares it to the planned path, then feeds back correction vectors to the robot controller to adjust torch position in real-time, improving welding accuracy through closed-loop control
Solution Approach 2:
A communication network acts as an intermediary between the robot controller, position sensors, and external systems, enabling data exchange and coordination without requiring direct complex connections between all components
2Productivity
If traditional welding systems operate at higher speeds, then productivity increases, but welding accuracy deteriorates due to limited communication speed and inability to perform real-time adjustments
Solution Approach 1:
Real-time feedback from position sensors allows the system to detect and correct path deviations immediately during high-speed welding, maintaining accuracy despite increased welding speed
Solution Approach 2:
The system calculates correction vectors based on detected deviations and applies them proactively to subsequent torch positions, preventing accuracy degradation before it occurs during high-speed operation
3Manufacturing precision
If real-time position tracking and correction systems are implemented, then welding accuracy and control are improved, but communication requirements and system complexity increase
Solution Approach 1:
The communication network serves as an intermediary that enables efficient data exchange between sensors, controllers, and external systems, preventing information loss through standardized protocols and real-time data transmission

AI summary
A system and method of electric arc welding that includes a welding apparatus having an electric arc welder torch with sensors to determine the absolute position of the torch tip and the relative position of the torch tip to the weld joint during automatic welding. Combining absolute and relative positional data can be used to adjust the path of the robot during automated or robotic welding in response to variations in the weld joint.
