← TechnologyWhich risk increases using inverse kinematics for robotic welding with position encoder drift?
A)Decreased weld pool solidification rate
B)Cumulative positional errors increase✓
C)Arc instability lowers penetration
D)Shielding gas layer gets disrupted
💡 Explanation
When inverse kinematics drives the robot based on drifting encoder data, the positional inaccuracies accumulate because each movement compounds preceding errors via path planning. Therefore positional errors increase over planned points rather than uniform reduction in penetration which would require change of arc.
