  1. 1. Study of process parameters in laser beam welding of copper hairpins

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Dan Lönn; David Spångberg; [2022]
    Keywords : Laser Welding; Hairpin Welding; Copper Laser Welding; Process Parameter; Multi-Physical Simulation; Computed Tomography Scan; Design of Experiment;

    Abstract : This study had the purpose to further the use of industrial lasers in the manufacturing of hairpin electric motors by optimizing the process of contacting the hairpins. A problem with laser beam welding of copper is the porosity created in the process which can lead to increased resistance of the welded region along with degraded mechanical properties. READ MORE

  3. 2. Design Study of Welded Beam Bracket According to Stress Concentrations in the Weld

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

    Author : FREDRIK EKLUND; [2021]
    Keywords : Plug weld; slot weld; welded beam; welded beam bracket; welded bus chassis; Pluggsvets; svetsad balk; svetsad busschassi; svetsad ram;

    Abstract : In a bus chassis, welded connections are often preferred to other fastening techniques due to low cost and broad competence among suppliers but are usually the weakest parts due to fatigue life. Evaluation of welds is often costly in time and competence. READ MORE

  4. 3. Development of a Beam for a Vibration Motor

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Kalle Nysell; Charlie Adam; [2021]
    Keywords : Finite element method; CAD; Inventor; mechanics; strength of materials; stress; development; design; Autodesk; Nastran; screen machine; material fatigue;

    Abstract : This project is centered around the use of finite element analysis for developing a beam for a new type of motor used in a screening machine. Essentially the main purpose of the developed beam is to transfer vibrations to the screen machine that it will be attached to. READ MORE

  5. 4. Infuence of the modelling of truss joints made of hollow tube sections in finite element models

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

    Author : Mattheüs Lucassen; [2019]
    Keywords : Truss joints; Circular Hollow Sections CHS ; Fatigue; Finite Element Modelling FEM ; Crane; Boom section; Local joint exibility LJF ; Stress concentration factors SCF ; Fackverksled; Cirkulära ihåliga proler; Utmattning; Finita Elementmetoden FEM ; Kran; Kranarmsektion; Lokal ledexibilitet; Spänningskoncentrationsfaktorer.;

    Abstract : Several boom segments form the crane boom. These segments are often truss structures formed out of circular hollow sections, which are welded together forming the truss joints. A adequate modelling of these truss joints is very important for operational strength and life. READ MORE

  6. 5. A Study in How Welding Parameters Affect the Porosity in Laser Welded High Pressure Die Cast AM50 Magnesium Alloy

    University essay from KTH/Materialvetenskap

    Author : Edwin Bergstedt; [2017]
    Keywords : Laser welding; AM50; Die Cast; Magnesium; Porosity;

    Abstract : There are a need for reducing the weight of vehicles, one solution is to implement cast lightweight materials such as the high pressure die cast AM50 magnesium alloy. The weldability of this cast alloy is poor and to implement the use of the alloy commercially a welding process is needed that limits the porosity of the weld. READ MORE
