Robotics welding

Lectures

Goal

The student gains fundamental knowledge about industrial robots, the necessary knowledge about robot control and artificial intelligence, the knowledge and skills needed for robot programming, the introduction to basic concepts in welding, and the specifics of the arc and electric resistance welding processes.

Outcome

Completing this course, students will be able to independently write programs to follow the trajectories needed to perform spot and arc welding tasks.

Theoretical teaching

1. Definitions and classification of industrial robots. Configurations. 2. Mechanical structure of industrial robots. Singularities. 3. Spatial descriptions and transformations. Homogeneous transformations-coordinate systems. 4. Kinematics (joint and world coordinates, DH algorithm, direct and inverse kinematic problem). 5. Robot sensors. Robot control (PTP and CP control). 6. Artificial intelligence. Intelligent control. 7. Programming of industrial robots. 8. General introduction to welding technology. Classification of welding processes. Symbolic representation of welded joints. 9. Arc welding and equipment. 10. Resistance welding. 11. The technology of arc welding and resistance welding processes.

Practical teaching

Three exercises: Spatial relations and transformations; Direct kinematic problem; Inverse kinematic problem. Three laboratory exercises: Modeling and simulation of industrial robot systems; Robot programming; Arc welding processes. Spot welding;
