  2. 6. Technical development of the laser welding process

    Author : Klas Nilsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : This thesis describes the technical development of the laser welding process and presents the results from a number of experimental investigations. The seven papers that make up the thesis investigate various aspects of the technical development of the laser welding process mechanism as well as industrial applications. READ MORE

  4. 7. Hot forming tribology : galling of tools and associated problems

    Author : Leonardo Pelcastre; Ewald Badisch; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements; Centrumbildning - Centrum för högpresterande stål CHS ; Centre - Centre for High Performance Steel CHS ;

    Abstract : In recent years, the use of ultra high-strength steels (UHSS) as structural reinforcements and in energy-absorbing systems in automobiles has increased rapidly; mainly in view of their favourable strength to weight ratios. However, due to their high strength, the formability of UHSS is poor, thus complex-shaped UHSS components are invariably produced through hot-metal forming processes. READ MORE

  5. 8. Simulation of manufacturing sequences for verification of product properties

    Author : Mats Werke; Torsten Kjellberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing engineering and work sciences; Produktion och arbetsvetenskap;

    Abstract : The manufacturing sequence may to a large extent influence properties like residual stresses and hardness and, as a consequence, the fatigue life and shape accuracy of a component. By simulating the manufacturing sequence and extract important accumulated data, the possibilities of early analysis of a design concept of a component and optimisation of the complete manufacturing sequence may increase.
