  1. 11. Numerical simulation of residual stresses in a weld seam : An application of the Finite Element Method

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Maciej Maczugowski; [2017]
    Keywords : Finite element method; residual stresses; temperature distribution; fatigue life; weld power; time step; T-joint weld model; Butt weld model.;

    Abstract : Articulated haulers are fundamental equipment to transport material. The load carrying structure on a hauler consists mainly of welded frames. During welding of the frames high residual stress will be introduced. These stresses may have a significant impact on the fatigue life of the frames. READ MORE

  3. 12. 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. 13. 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. 14. Robotic 3D friction stir welding : T-butt joint

    University essay from Högskolan Väst/Avd för automationssystem

    Author : Cheng Zhang; [2015]
    Keywords : Friction stir welding; robotic friction stir welding; three-directional welds;

    Abstract : This Master Thesis was performed in terms of robotic three dimensional friction stir welding with T-butt joint. Friction stir welding (FSW) is a solid state welding method that achieves the weld temperature by friction of a rotating non-consumable tool with the workpiece. READ MORE

  6. 15. Weld Quality in Aluminium Alloys

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Rujira Ninni Deekhunthod; [2014]
    Keywords : Weld Aluminium Alloys MIG MAG;

    Abstract : The aims of this project are to present an understanding in what happens when aluminium-(Al) alloys are welded, and to investigate how the Mg-, Si- and Cr-contents in AA6005A influence the weld strength and cracking susceptibility. It is known that heat from welding affects the mechanical properties (strength) of the material. READ MORE
