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. The Nordic Keyhole : quantitative analysis of its use in productreformulation and development

   University essay from SLU/Department of Molecular Sciences

   Author : Cecilia Andersson; [2021]
   Keywords : The Nordic Keyhole; Criteria; Food groups; FOPNL; Health;

   Abstract : Front of pack nutrition label (FOPNL) could be used to guide consumers to healthier choices. FOPNL were therefore used as a tool for consumers to give guidelines in choosing healthy food. READ MORE

6. 5. En utredning av Nyckelhålet med fokus på miljömässig hållbarhet : ger kriterierna vägledning för Livsmedelsverkets kostråd ”ät grönare”?

   University essay from SLU/Department of Molecular Sciences

   Author : Elsa Ramberg; [2019]
   Keywords : Nyckelhålet; miljömässig hållbarhet; hälsa; Vegetabiliska alternativ till kött och mejeri; SLVFS 2015:1;

   Abstract : Diskussionen om klimat och miljö tar allt större plats i vår vardag och under de senaste åren har livsmedelsproduktionens koppling till dessa ämnen uppmärksammats. Medvetenheten om vilka livsmedel som är miljömässigt hållbara ökar och mycket forskning tyder på att livsmedel baserade på vegetabiliska råvaror har lägre klimatpåverkan i koldioxidutsläpp såväl som vattenanvändning och landanvändning än animaliska livsmedel.
