  1. 1. Study of process parameters in laser beam welding of copper hairpins

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Dan Lönn; David Spångberg; [2022]
    Nyckelord :Laser Welding; Hairpin Welding; Copper Laser Welding; Process Parameter; Multi-Physical Simulation; Computed Tomography Scan; Design of Experiment;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Industriell produktion

    Författare :Björn Lindeberg Nilsson; [2022]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

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

    Sammanfattning : 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. LÄS MER

  5. 4. Jämförelse mellan vågformsstyrda processer och konventionell spraybåge vid användning av solidtråd : Möjligheter att uppnå av Volvo CE ställda krav och potentiella vinster

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :DANIEL KARLSSON; [2021]
    Nyckelord :Gas metal arc welding; MAG; spray transfer; waveform controlled processes; solid wire; penetration; toe transition; weld trials; Volvo; fillet welds; industry; Gasmetallbågsvetsning; MAG; spraybåge; vågformsstyrda processer; solidtråd; inträngning; fattningskanter; svetsförsök; Volvo; kälsvets; industri;

    Sammanfattning : Detta arbete har genomförts vid Volvo Construction Equipment i Braås. I nuläget används konventionell spraybågssvetsning med metallpulverfylld rörtråd i produktionen. Ett alternativ som övervägs är att byta till solidtråd. Huvudsyftet med detta arbete har varit att utreda huruvida några utvalda processer med 1. LÄS MER

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

    Master-uppsats, Lunds universitet/Innovation

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

    Sammanfattning : 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.
