3. 2. 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. 4. Characterization of the ethylene-vinyl acetate copolymer and the influencing parameters of the weld in intravaginal rings

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Ludwig Kaindl; [2020]
   Keywords : Ethylene-vinyl acetate; Intravaginal rings; DSC; Thermal properties EVA; Welding; Pharmaceutical Technology; Läkemedelsteknologi; Technology and Engineering;

   Abstract : The aim of this thesis was to characterize the mechanical and thermal properties of three different ethylene vinyl acetate (EVA) polymers with varying vinyl acetate (VAc) content and to investigate the influential parameters when welding the polymer into intravaginal rings. A second purpose in this study was to compare two different produced EVA polymers with the same VAc content to find thermal and structural differences. READ MORE

6. 5. Modelling of Laser Welding of Aluminium using COMSOL Multiphysics

   University essay from KTH/Materialvetenskap

   Author : Jie Chen; [2020]
   Keywords : laser welding process; aluminium alloy; thermal-mechanical; COMSOL Multiphysics; hot cracking; thermal model; CFD model; mechanical model; Marangoni effect; lasersvetsningsprocess; aluminiumlegeringar; termisk-mekanisk; COMSOL-flerfysik; hetsprickning; termisk modell; CFD-modell; mekanisk modell; Marangoni-effekt;

   Abstract : This thesis presents a modelling approach of laser welding process of aluminium alloy from the thermo-mechanical point of view to evaluate the occurrence of hot cracking based on simulation results and relevant criteria. The model was created stepwise in COMSOL Multiphysics, starting with the thermal model where heat conduction of solid and liquid phase was computed. READ MORE
