  1. 1. Accuracy Improvement and Joint Stiction Relieve in Robot Arms Movement Applying Torque-Based Cartesian Impedance Control With Dithering

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Salvador Monzó Martínez; Altin Zejnullahu; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Robots are nowadays present and essential in a wide range of applications, and robot arms in particular are capable of performing various tasks such as inspection, material handling, and welding. They can be classified into several types, depending on their structure and purpose. LÄS MER

  3. 2. Adaptive Welding Trials – Into Robotic Systems : A pre-welding study to see the possibilities and challenges for adaptive welding implementation

    Master-uppsats, KTH/Produktionsutveckling

    Författare :Holger Johansson; [2023]
    Nyckelord :;

    Sammanfattning : This diploma project investigates a practical approach to adaptive welding. The goal was to evaluate the possibility for implementation of adaptive welding, and the diploma work comprised theoretical work and evaluations of adaptive welding of one of the welds on a front frame.

  4. 3. Projection Nut Welding to High- and Ultra-high Strength Steels

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Love Englund; [2023]
    Nyckelord :mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

    Sammanfattning : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. LÄS MER

  5. 4. 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
