    Författare :Alec Chamberlain; Harald Larsson; Louise Nilsson; Daniel Vasquez; Samir Schouri; Elin Myrsell; Sally Walin; [2019]
    Nyckelord :Resistance spot welding; laser beam welding; ultrasonic welding; battery cell; electrical performance; weld quality; cost analysis; automation degree; production yield;

    Sammanfattning : The demand for high energy battery assemblies is growing in sectors such as transportation. Alongwith it is the need for reliable, efficient and cost-effective ways to electrically connect the batteries toensure their performance. Battery cells are most often put into modules or packs when produced forelectrically driven vehicles. LÄS MER

  2. 2. Lasersvetsning : En genomförbarhetsstudie av stora rotationssymmetriska komponenter med varierande materialsorter

    Master-uppsats, KTH/Industriell produktion

    Författare :Johan Nilsson; [2018]
    Nyckelord :;

    Sammanfattning : A big problem with welding is that it is hard to predict how a high heat canaffect different materials. The effects that can appear is shape changes in thematerial and brittle structures. The brittle structures will affect the strengthof the material and if the shape changes are big, the fatigue strength of thecomponents will be limited. LÄS MER

  3. 3. Innovative Methods for Welding Ultra High Strength Steel with Resistance Spot Welding

    Master-uppsats, KTH/Industriell produktion

    Författare :Rickard Aldén; [2018]
    Nyckelord :;

    Sammanfattning : Resistance spot welding (RSW) is the most frequently used method for welding thin sheets in manufacturing industries such as the automotive industry, because of the high productivity of RSW. In order to reduce CO2 emissions the automotive industry strives towards creating structures of light weight, this is partly achieved by the use of lightweight materials such as Aluminum and composite materials.

  4. 4. Using gallium nitride nanowires as STM probes

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Karolis Sulinskas; [2018]
    Nyckelord :STM; STS; Nanowire; GaN; InAs; Semiconductors; Physics and Astronomy;

    Sammanfattning : Gallium nitride (GaN) nanowires grown using catalyst-free metal organic vapor phase epitaxy were used as scanning tunneling microscope (STM) probes. The probes were prepared by placing a GaN nanowire on a tungsten STM probe using a nanomanipulator in a scanning electron microscope (SEM) and welding them together using an electron beam induced platinum deposition.
