    Sammanfattning : In arc welding the quality of the weld is strongly influenced by the thermal history of the workpiece which is itself governed by the electric arc heat source. The models for predicting weld properties thus need a good evaluation of the distribution of the heat input from thearc to the workpiece. LÄS MER

  4. 33. Simulation and execution of autonomous robot systems

    Författare :Magnus Olsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Elektronik och elektroteknik; sensor simulation robotics; Electronics and Electrical technology; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Traditional off-line programming is not enough in order to use the full potential of virtual models and simulation system in industrial robot applications. The interface between off-line programming system and the robot controller is today restricted to program transfer. LÄS MER

  5. 34. Simulation of multipass welding to reduce intergranular stress corrosion cracking

    Författare :Erika Hedblom; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : This thesis describes the use of the finite element method for simulation of multipass welding. The simulations have been used to find welding procedures that minimises tensile residual stresses on the inside of the studied pipes. This will lead to a reduced risk for Inter Granular Stress Corrosion Cracking. LÄS MER
