  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. Laser Arc Hybrid Welding of Thicker 6000-series Aluminium Alloy : Laser-MIG butt welding of 8 mm 6082-t6

    University essay from KTH/Industriell produktion

    Author : Björn Lindeberg Nilsson; [2022]
    Keywords : ;

    Abstract : Laser arc hybrid welding presents many benefits but has many parameters that must be optimised for it to work. It becomes even more challenging when welding thicker aluminium with the process. Welding of thicker aluminium alloys involves a lot of different challenges, on itself. READ MORE

  4. 3. Implementation of thermomechanical laser welding simulation : Predicting displacements of fusing A AISI304 T-JOINT

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Anton Rolseth; Anton Gustafsson; [2021]
    Keywords : Laser welding; Finite element method; ABAQUS; Thermomechanical simulation; Heat source models; DFLUX; Element activation;

    Abstract : Laser welding is an advanced joining technique with the capability to form deep, narrow, and precise welds. Numerical models are used to simulate the process in attempts of predicting distortions and stresses in the material. This is done to reduce physical testing, optimize processes and enable integrated product- and process development. READ MORE

  5. 4. 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.

  6. 5. 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
