Welding Robot Path Interpolation
Welding robot path interpolation calculates intermediate points along a given curve to ensure smooth motion. This is crucial for constant travel speeds and optimal weld quality.
Physicochemical Mechanism of Action
Path interpolation mathematically calculates intermediate points on a given curve so the robot makes a smooth movement. This is achieved by continuously adjusting the robot's speed so it always covers the same distance between intermediate points.
Metallurgical Relevance & Welding Risks
Uneven robot movement can lead to a variable travel speed. That can cause certain areas of the weld to overheat or stay too cool, causing pores, distortion or uneven hardness. Optimal interpolation ensures a consistent, high-quality weld.
Workshop Practice & Instructions
For good path interpolation, these points matter:
• Curve accuracy: The curve must be as precise as possible to optimize robot movement.
• Travel speed: Keep the speed constant, e.g. 50 mm/s for steel.
• Spacing between intermediate points: Choose it so the robot makes a smooth movement without abrupt speed changes.
