  1. 21. Evaluation of welding joint methods for a prismatic battery cell module

    University essay from Lunds universitet/Innovation

    Author : William Hellingwerf; [2021]
    Keywords : Aluminium welding methods; Battery module; Prismatic cell; Weld strength; Weld analysis; Weld temperature simulation; Technology and Engineering;

    Abstract : Prismatic battery cells swell due to a number of different factors, such as state of charge, temperature and irreversibly with charge cycling. Cell health can be improved by restricting the swelling of the cell, and therefore, the container which holds the cells, the module, should be able to restrict the swelling, and thus withstand the force exerted by the cells.

  3. 22. Laser-arc hybrid welding of high strength steel : Weld quality and process stability

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : David Lohse; [2021]
    Keywords : Laser; arc; hybrid; welding; high; strength; steel; high-strength; HSLA; weld quality; process stability;

    Abstract : The development of high strength steel enables constructions to be made with less material than with previous used steel grades. The possibility of creating lightweight constructions with the same or even better mechanical properties is of high focus in the steel industry today. READ MORE

  4. 23. Modernized 6 and 10-ton Dock Levelers

    University essay from Lunds universitet/Innovation

    Author : Viola Nilsson; Rebecka Karlsson; [2021]
    Keywords : Dock leveler; FEM; stress; sheet metal; load case; Technology and Engineering;

    Abstract : This Master Thesis is made in collaboration with ASSA ABLOY Entrance Systems and addresses the issues and problem areas of two dock leveler models; 60 kN and 100 kN to find a new improved design. After the following product development process, a new concept was created which could withstand applied forces exceedingly. READ MORE

  5. 24. 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

  6. 25. Laser ablation of aluminium before welding : Effect of weld preparation on number and sizes of pores

    University essay from KTH/Materialvetenskap

    Author : Olivia Taivalkoski; [2021]
    Keywords : ;

    Abstract : Welding aluminium often results in porosity in the weld. One way to reduce porosity is by carful weld preparation and cleaning. In this master thesis report laser ablation was done on aluminium plates before welding to remove dirt and the surface oxide layer. READ MORE
