1. 1. Evaluation of pretension losses in heated screw joint

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

   Author : Joel Svensson; [2022]
   Keywords : screw joint; clamping force; thermal load;

   Abstract : The heated flow within the silencers of heavy transport vehicles can easily reach temperatures of hundreds of degrees Celsius. The thermal loads can cause problems for certain components on a silencer. READ MORE

3. 2. 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. Welding methods for electrical connections in battery systems

   University essay from Uppsala universitet/Institutionen för teknikvetenskaper

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

   Abstract : 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. READ MORE

5. 4. Phased Array Ultrasonic Testing of Austenitic Stainless Steel Welds of the 11 T HL-LHC Dipole Magnets

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Marcus Lorentzon; [2018]
   Keywords : Phased Array Ultrasonic Testing; PAUT; Non-Destructive Testing; Austenitic Stainless Steel; Welds; CERN;

   Abstract : A routine non-destructive test method based on Phased Array Ultrasonic Testing (PAUT) has been developed and applied for the inspection of the first 11 T dipole prototype magnet half shell welds, and the test results are compared with the radiography and visual inspection results of the same welds. A manual scanner and alignment system have been developed and built to facilitate the inspection of the 5. READ MORE

6. 5. Control strategies and inspection methods for welded part

   University essay from Avdelningen för maskin- och materialteknik

   Author : Divyank Baradi; [2013]
   Keywords : Visual inspection; WPS; impressions; throat size gauge; radius gauge; liquid penetrant test; magnetic particle testing; eddy current; radiography; ultrasonic PAUT TOFD ; thermography; control plan; cost per hour.;

   Abstract : Present and future demonstrator designs were used to demonstrate the quality assurance of welds. The NDT methods tested on prototype demonstrator parts are: visual inspection, radius gauges, throat size gauge, liquid-penetrant testing, magnetic particle testing and ultrasonics with pulse echo and phased array.
