1. 1. Resistance Element Welding of Ultra High Strength Steel to Aluminium

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

   Author : Malte Eriksson; [2023]
   Keywords : ;

   Abstract : The automotive industry strives towards decreased vehicle weight in order to decrease green house gas emissions. To create lighter vehicles, new lighter materials need to be implemented. One issue with new materials is that the traditional joining methods in many cases meet their limitations. READ MORE

3. 2. Evaluation of Shunt Distance in Resistance Spot Welding

   University essay from KTH/Materialvetenskap

   Author : Daniel Fredriksson; Milou Carlfors Göransson; [2020]
   Keywords : Resistance spot welding; RSW; Shunt effect; Shunting; Shunt distance; One-dimension welding lobe; Punktsvetsning; RSW; Shunt effekt; Shuntning; Shuntavstånd; Endimensionell svetslob;

   Abstract : The purpose of this study was to generate a greater understanding of how the shunt distance affects the shunting phenomena which occurs when working with resistance spot welding (RSW). Shunting affects the quality of the weld and the goal of the study was to create guidelines for RSW to minimize its impact on the weld quality. READ MORE

4. 3. Techniques for Improving Weldability and Testing of Weld-bonded Joints

   University essay from KTH/Maskinkonstruktion (Inst.)
