1. 1. FE-Modelling of Composite Girder tests

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Holger Berggren; Bergstedt Ola; [2024]
   Keywords : shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

   Abstract : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. READ MORE

3. 2. Automating a robot cell welding process

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Elias Ljunglöv; [2022]
   Keywords : stud bolt welding quality; accuracy in automated welds; welding unit fail-safe; brazed plate heat exchangers; programmable logic controller; human-machine interface; Technology and Engineering;

   Abstract : Today, the importance of sustainable and effective energy usage is rapidly growing. SWEP International AB leads the manufacturing of brazed plate heat exchangers that offer effective heating and cooling applications used in a wide range of systems and industries. READ MORE

4. 3. Characterization of Fiber Orientation and Weld Line Effects in Reinforced Plastics with Reduced CO2eq Emissions

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Anders Tolf; Markus Johannesson; [2022]
   Keywords : Fiber-reinforced plastics; GFRP; Reduced carbon dioxide equivalent materials; Experimental; Uniaxial tensile test; Uniform fiber orientation plate; Tensile strength; Fiber orientation; Weld line; Fracture analysis; Microscopy;

   Abstract : With increasing emphasis and regulations on the environmental footprint in industries, the integration of reduced carbon dioxide equivalent (CO2eq) plastic materials is desirable. Fiber-reinforced plastic materials mechanical properties differ with varying fiber orientations. READ MORE

5. 4. Modelling of Laser Welding of Aluminium using COMSOL Multiphysics

   University essay from KTH/Materialvetenskap

   Author : Jie Chen; [2020]
   Keywords : laser welding process; aluminium alloy; thermal-mechanical; COMSOL Multiphysics; hot cracking; thermal model; CFD model; mechanical model; Marangoni effect; lasersvetsningsprocess; aluminiumlegeringar; termisk-mekanisk; COMSOL-flerfysik; hetsprickning; termisk modell; CFD-modell; mekanisk modell; Marangoni-effekt;

   Abstract : This thesis presents a modelling approach of laser welding process of aluminium alloy from the thermo-mechanical point of view to evaluate the occurrence of hot cracking based on simulation results and relevant criteria. The model was created stepwise in COMSOL Multiphysics, starting with the thermal model where heat conduction of solid and liquid phase was computed. READ MORE

6. 5. Researching and Developing Universal Gas Purging Solutions

   University essay from KTH/Maskinkonstruktion (Avd.)

   Author : Ludvig Briheim; Dennis Ståhl; [2020]
   Keywords : Gas Purging Plug; Pipe Purging; Root Shielding; Shielding Gas; Pipe Welding; Rotgasplugg; Rotgasskydd; Skyddsgas; Rörsvetsning; Rörrengöring;

   Abstract : In the welding of more sensitive metals such as stainless steel, titanium and some specific nickel alloys, the presence and application of a protective gas is essential. Without the use of a nonreactive shielding gas, defects occur in or adjacent to the weld joint, which vary from light discoloration of the weld bead to the direct onset and propagation of cracks.
