After completing this course the student is able to recognize the characteristics of welding arc and heat flow as well as estimate their effect ton weld pool behavior and parent metal. In addition, the student will be able to interpret the metallurgical effects in the parent metal and contraction and residual stress in welded structure. Students will be able to use simulation software to estimate distortions and metallurgical changes in structures. The student will be aware of modern IT Products available in development of workshop operations. The student will be able to use simulation software to model a robot welding station, simulate its operation and make offline programming.


Heat flow in arc and in weld pool. Cooling rate, heat conduction and temperature distribution in welds. Simulation of weld distortion and metallurgy. Weld pool solidification. Metallurgical effects in the parent metal. Contraction and residual stress in welded structures. Modeling of robot welding system and simulation of robot operation. Optimization of operation cycles. Weldability of welded products and accessibility of robot tools in welding performance.
