1. 6. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Bakhtiar Afzalan; [2021]
   Keywords : Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

   Abstract : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. READ MORE

3. 7. 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

4. 8. Modelling, Evaluation and Assessment of Welded Joints Subjected to Fatigue

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Prajeet Rajaganesan; [2020]
   Keywords : Welded joints; Fatigue Assessments; Hot Spot method; Python Automation; Post-processing; Abaqus;

   Abstract : Fatigue assessment of welded joints using finite element methods is becoming very common. Research about new methods is being carried out every day that show a more accurate estimation of the fatigue life cycle than the previous ones. READ MORE

5. 9. Fillet Weld Fatigue Lifetime : Parametric Finite Element Analysis

   University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Author : Vishal Singaravadivelu; Sai Krishna Vemulapalli; [2020]
   Keywords : Fatigue Strength; Fillet weld; Weld toe radius; Effective notch stress method; Parametric Finite Element Analysis - PFEA;

   Abstract : The fatigue life time of welded components is the dominant factor at the design of mechanical and automotive structures and components where fatigue failure has a crucial outcome in use of fillet welded structures and it commences mostly from the weld toe and propagate to the parent material or even to the weld root area. Fillet welds are the imperative type of weld used in many industries because of the geometry and fabrication cost of the structure. READ MORE

6. 10. 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
