6. Laser Arc Hybrid Welding of Thicker 6000-series Aluminium Alloy : Laser-MIG butt welding of 8 mm 6082-t6
Master-uppsats, KTH/Industriell produktionSammanfattning : 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
7. Applikationer för effektiv inlinekontroll inom svetsande industri : Möjligheter och utmaningar vid implementering av nya kontrollmetoder
Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Svetsning är en viktig fogningsmetod, och kvalitet på svetsar kan ha hög inverkan på prestanda och livslängd för svetsade produkter. För att kunna garantera att svetsar lever upp till de krav som ställs används ofta oförstörande provning. LÄS MER
8. Design Study of Welded Beam Bracket According to Stress Concentrations in the Weld
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In a bus chassis, welded connections are often preferred to other fastening techniques due to low cost and broad competence among suppliers but are usually the weakest parts due to fatigue life. Evaluation of welds is often costly in time and competence. LÄS MER
9. Modelling of contacts in Adams flex bodies using Mamba
Master-uppsats, KTH/FordonsdynamikSammanfattning : Simulations are a powerful tool used to reduce development time and cost in the vehicle industry. However, the models used in simulations are simplifications of reality, and there are commonly contradicting requirements between accuracy and computational efficiency. LÄS MER
10. Laser ablation of aluminium before welding : Effect of weld preparation on number and sizes of pores
Uppsats för yrkesexamina på avancerad nivå, KTH/MaterialvetenskapSammanfattning : 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. LÄS MER
