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

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap; 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

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

    University essay from Lunds universitet/Produktutveckling

    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. 3. 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. 4. 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

  5. 5. 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
