1. 1. Optimization of adaptive control for spot welding

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

   Author : Felix Lindblom; [2021]
   Keywords : ;

   Abstract : In December 2015 Scania Oskarshamn started production in their new facility for the body in white (BiW) production. Heat capacity control (HCC) is used to control the RSW process for all the welding robots in this facility for BiW at Scania Oskarshamn. 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.)

   Author : Mattias Högsäter Myhr; [2020]
   Keywords : Adhesives; Automotive industry; Resistance Spot Welding; RSW; Weldability; Weld-bonding; Welding parameters; Fordonsindustri; Limning; Limpunktsvetsning; Motståndssvetsning; Punktsvetsning; Svetsbarhet; Svetsparametrar;

   Abstract : Increased understanding of improving the weld-bonding process is essential in order for the automotive industry to constantly develop their designs and production processes for the energy-efficient vehicles of the future. The joining method of weld-bonding, a hybrid method of adhesive joining and resistance spot welding, has introduced new challenges in the manufacturing and design of auto bodies. READ MORE

5. 4. Resistance Spot Welding of AlSi-coated Ultra High Strength Steel : An experimental study

   University essay from KTH/Materialvetenskap

   Author : Kristofer Hjelmtorp; [2019]
   Keywords : RSW; resistance spot welding; usibor; boron steel;

   Abstract : The automotive industry of today faces ever harder requirements from regulatory bodies to increase the fuel efficiency, reduce the carbon footprint and increase the safety of their vehicles. The problem is being tackled in different ways; one of them being the use of innovative materials to reduce the overall weight while improving the crash safety of the vehicle. READ MORE

6. 5. Innovative Methods for Welding Ultra High Strength Steel with Resistance Spot Welding

   University essay from KTH/Industriell produktion

   Author : Rickard Aldén; [2018]
   Keywords : ;

   Abstract : Resistance spot welding (RSW) is the most frequently used method for welding thin sheets in manufacturing industries such as the automotive industry, because of the high productivity of RSW. In order to reduce CO2 emissions the automotive industry strives towards creating structures of light weight, this is partly achieved by the use of lightweight materials such as Aluminum and composite materials.
