  1. 6. FE-model for prediction of welding distortions in components made of preformed stainless steel sheets

    University essay from KTH/Hållfasthetslära

    Author : Tom Glansholm; [2020]
    Keywords : Welding simulation; distortions; Ferritic stainless steel; EN1.4509; FEM; Solid mechanics; Residual stresses; Svetssimulering; deformationer; restspänningar; Ferritiskt rostfritt stål; EN1.4509; Finita elementmetoden; Hållfasthetslära;

    Abstract : This master thesis was carried out at Scania CV AB. The focus for this thesis is the prediction of welding distortions that can cause problems in the manufacturing process of Scania's after-treatment system. The after-treatment system is mainly assembled by sheet metal plates of the ferritic stainless steel EN 1.4509. READ MORE

  3. 7. Techniques for Improving Weldability and Testing of Weld-bonded Joints

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Mattias Högsäter Myhr; [2020]
    Keywords : Adhesives; Automotive industry; Resistance Spot Welding; RSW; Weldability; Weld-bonding; Welding parameters; Fordonsindustri; Limning; Limpunktsvetsning; Motståndssvetsning; Punktsvetsning; Svetsbarhet; Svetsparametrar;

    Abstract : Increased understanding of improving the weld-bonding process is essential in order for the automotive industry to constantly develop their designs and production processes for the energy-efficient vehicles of the future. The joining method of weld-bonding, a hybrid method of adhesive joining and resistance spot welding, has introduced new challenges in the manufacturing and design of auto bodies. READ MORE

  4. 8. Pitting Corrosion Evaluation of Post-Weld Cleaning Methods for Stainless Steel Welds

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

    Author : Jimmy Holgersson; Klara Trydell; [2019]
    Keywords : ;

    Abstract : Welding stainless steel creates an oxide film, heat tint, on the surface and around the joint. It disrupts passivation and influence the corrosion resistance for the material. The result is often a decrease in pitting corrosion resistance for the joint and surrounding area. The heat tint is therefore commonly removed by post weld cleaning. READ MORE

  5. 9. 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. 10. Optimization and development of the welding system for fiber-optic duct joints

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Jiatong Duan; [2019]
    Keywords : Electrofusion welding; Fiber-optic duct; Current Measurement; dsPIC33FJ16GS404; Capacitor bank;

    Abstract : At present, the fiber optic ducts are connected by a mechanical type of joint. In this method, two ducts cut in the right angle are pushed in from both sides of the joint, and takes approximately one second to joint ducts together. READ MORE
