  1. 16. A digital image correlation method for detection of fatigue cracks in non-load carrying T-joints

    University essay from KTH/Lättkonstruktioner

    Author : Björn Jonsson; [2018]
    Keywords : ;

    Abstract : In dynamical loaded welded structures fatigue life is often a limiting factor. Common practise is to reduce nominal stress by increased material thickness which leads to oversized, heavy structures. Those practises are replaced by improvement of production and designingtechniques to utilize better properties of high strength steels. READ MORE

  3. 17. Evaluation of an External Axis for Tool Manipulation in Robotized Laser Beam Welding

    University essay from Högskolan Väst/Avdelningen för produktionssystem (PS)

    Author : Civan Ulucan Dayan; [2017]
    Keywords : Welding applications; manipulation; twincat; external axis; osition accuracy;

    Abstract : Laser beam welding applications are widely used in the industry. However, laser beam welding applications have a very small position tolerance to an offset. In this project, the offset is defined as the distance between the point, which the laser tool welds, and the point which laser tool should weld the weld joint. READ MORE

  4. 18. Welding of dissimilar metals in different welding positions

    University essay from KTH/Materialvetenskap

    Author : Mimmi Bäck; [2016]
    Keywords : ;

    Abstract : The three boiling water reactors (BWR) in Oskarshamn produce about 10 % of the electrical power in Sweden. The combination of intense radiation fluxes and high temperatures in nuclear reactors creates an extraordinary environment. READ MORE

  5. 19. Strengthening of I-girder bridges : Fatigue endurance

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Olle Edström; [2016]
    Keywords : ;

    Abstract : Structures have always been subjected to the detrimental consequences of the fatigue phenomenon. The consequences due to this damaging effects leads to crack initiation and the ultimate result being complete failure. Fatigue appears on structures that has to endure fluctuating loads over a long period. READ MORE

  6. 20. Fracture Simulation of Electrofusion Joining.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Amir Alizadeh; [2015]
    Keywords : ;

    Abstract : This Master thesis investigates mechanical failures of electrofusion joints. This type of joints are used for weld high density polyethylene pipe systems where tting and pipe will be welded together by the heat caused by the resistance of the copper cables to electric current.
