  1. 11. Thermo-electric temperature measurements in friction stir welding : Towards feedback control of temperature

    Författare :Ana Magalhães; Gunnar Bolmsjö; Jeroen De Backer; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FSW; Robotic; Temperature; TWT; Plunge; Control; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Friction Stir Welding has seen a fast uptake in many industry segments. Mechanical properties superior to fusion welding, the ability to weld "unweldable" aluminium alloys and low distortion are often described as the main reasons for the fast industrial implementation of FSW. Most existing applications consist of long straight welding joints. LÄS MER

  3. 12. Affordable automation for airframe assembly : developing of key enabling technologies

    Författare :Henrik Kihlman; Mats Björkman; Giorgos Nikoleris; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Building aircraft is a challenging field. An aircraft has a life expectancy of 40 years, compared to just 10 years for a car. Given the vibrations of flying at close to Mach one at an altitude of 10,000 meters, these machines must function flawlessly in a tough environment. This demands high quality in the assembly processes. LÄS MER

  4. 13. Imaging and analysis methods for automated weld inspection

    Författare :Patrik Broberg; Tadeusz Stepinski; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Welding; materials; Manufacturing and materials engineering; Produktions- och materialteknik; Experimental Mechanics;

    Sammanfattning : All welding processes can give rise to defects, which weakens the joint and can eventually lead to the failure of the welded structure. In order to inspect welds for detects, without affecting the usability of the product, non-destructive testing (NDT) is needed. LÄS MER

  5. 14. Monitoring and Control of Robotized Laser Metal-Wire Deposition

    Författare :Almir Heralic; Alexander Kaplan; Högskolan Väst; []

    Sammanfattning : The thesis gives a number of solutions towards full automation of the promising manufacturing technology Robotized Laser Metal-wire Deposition (RLMwD). RLMwD offers great cost and weight saving potentials in the manufacturing industry. LÄS MER

  7. 15. Energy Reduction of Robot Stations with Uncertainties

    Författare :Mattias Hovgard; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robot station; Stochastic uncertainties; Energy optimization; Industrial robot;

    Sammanfattning : This thesis aims to present a practical approach to reducing the energy use of industrial robot stations. The starting point of this work is different types of robot stations and production systems found in the automotive industry, such as welding stations and human-robot collaborative stations, and the aim is to find and verify methods of reducing the energy use in such systems.
