  2. 1. Modelling of Electric Arc Welding : arc-electrode coupling

    Author : Alireza Javidi Shirvan; Isabelle Choquet; Håkan Nilsson; Alexei Heintz; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric welding; arc welding simulation; electrode; plasma; cathode layer; sheath; arc discharge; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Arc welding still requires deeper process understanding and more accurateprediction of the heat transferred to the base metal. This can be provided by CFD modelling.Most works done to model arc discharge using CFD consider the arc corealone. READ MORE

    Abstract : Manufacturing of aero engine components requires attention to residual stress and final shape of the product in order to meet high quality product standards.This sets very high demands on involved manufacturing steps to meet design requirements. READ MORE

  6. 4. Simulation of welding and heat treatment : modelling and validation

    Author : Henrik Alberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : Many aerospace components with complex geometry are fabricated from smaller parts using joining techniques such as welding. Welding and the heat treatment which usually follows, can result in unwanted deformation and stresses. READ MORE

  7. 5. Simulation of robot paths and heat effects in welding

    Author : Mikael Ericsson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsteknik; Welding; Automation; robotics; Off-line programming; Robotics; Automatiska system; Production technology; control engineering; Finite Element Analysis; reglerteknik; robotteknik;

    Abstract : The objective of this thesis is to develop a simulation tool and a method by which robot trajectories, temperature histories, residual stresses and distortion can be analysed and optimized off-line. This was performed by integrating robot simulation software with finite element analysis software. READ MORE
