  1. 1. Isocyanates formation from thermal degradation of polyurethane foam during welding of district heating pipes

    University essay from KTH/Ergonomi

    Author : Muhammad Akram; [2023]
    Keywords : Polyurethane; Isocyanates; District Heating Pipes; Oxy-fuel Welding; Manual Metal Arc Welding;

    Abstract : Polyurethane insulation foam, which is used as insulation on district heating steel and copper pipes, is made from polymerisation of polyol and diisocyanates monomers. Installation of new district heating pipes or replacement of old pipes involves masses of welding activities. READ MORE

  3. 2. Resistance Element Welding of Ultra High Strength Steel to Aluminium

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Malte Eriksson; [2023]
    Keywords : ;

    Abstract : The automotive industry strives towards decreased vehicle weight in order to decrease green house gas emissions. To create lighter vehicles, new lighter materials need to be implemented. One issue with new materials is that the traditional joining methods in many cases meet their limitations. READ MORE

  5. 4. Projection Nut Welding to High- and Ultra-high Strength Steels

    University essay from KTH/Hållfasthetslära

    Author : Love Englund; [2023]
    Keywords : mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

    Abstract : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. READ MORE

  6. 5. The implementation of collaborative robots in production environments : a review of academic literature and industrial applications

    University essay from KTH/Industriell produktion

    Author : Daniele Marrone; [2022]
    Keywords : ;

    Abstract : The evolution of the global market that happened after the second world war has made competition between manufacturing companies much more difficult than before. In contrast to the days of Fordism, where mass production allowed companies to cut costs and have a profit margin through high productivity, flexibility is currently considered the key to surviving the competition and it require new production systems: information management systems and automated production systems that enable the expansion in product variety.
