  1. 1. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Bakhtiar Afzalan; [2021]
    Keywords : Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

    Abstract : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. READ MORE

  4. 3. Electrical connection for aluminium conductors in automotive applications : Prestudy of available solutions for electrical connection methods of aluminium cables

    University essay from KTH/Materialvetenskap

    Author : Emilia Hamedi; [2017]
    Keywords : Connector; electrical contact; termination; aluminium conductor;

    Abstract : Due to increasing weight of electrical component and wiring harnesses in a vehicle contrary to the demand of light constructed vehicles as well as the constantly increasing and fluctuating price of copper compared to aluminium’s stable and far lower price, the use of aluminium conductors as an alternative have been promoted.  This thesis work lay theoretical research of the available methods used for electrical connection of aluminium conductors in order to increase the knowledge about the available termination techniques.
