  1. 16. Fatigue analysis of laser welded hairpins in electric car motors

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Francisco Martín Ruiz; Imanol Iribar Rodriguez; [2022]
    Keywords : ;

    Abstract : Hairpins are copper filaments used in the windings in the stators of electric motors in modern times. For the motor to work, they have to be welded in pairs, normally with laser welding. Studying the fatigue response of the joint of hairpins welded with a set of values of laser welding process parameters is the main objective of this project. READ MORE

  3. 17. Design Study of Welded Beam Bracket According to Stress Concentrations in the Weld

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : FREDRIK EKLUND; [2021]
    Keywords : Plug weld; slot weld; welded beam; welded beam bracket; welded bus chassis; Pluggsvets; svetsad balk; svetsad busschassi; svetsad ram;

    Abstract : 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. READ MORE

  4. 18. Method development for fatigue lifeprediction in welded gearset joints undertorsional loading

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

  5. 19. Design and test of a robotic cell for stud bolt welding in heat exchangers for SWEP International AB

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Amparo Tarazona Ferrandis; [2021]
    Keywords : Technology and Engineering;

    Abstract : This project targeted automating production steps where stud bolts are welded on a heat exchanger within allowed perpendicularity and position requirements. Until now, this has been a manual process where an operator uses steel templates to position the bolts in the right place and manual welding guns to weld the bolts. READ MORE

  6. 20. Design Solution for Ingot Handling and Machining

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Johan Jönsson; [2021]
    Keywords : Mechanical Engineering; Product Development;

    Abstract : At the electro remelting slag (ESR) facility at Uddeholm, cylindrical steel ingots are produced in several different sizes. The ESR process requires a “starting step” that consist of a 20mm thick steel plate and is a little larger than the diameter of the ingot. READ MORE
