  1. 16. 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.

  3. 17. A comparative study between conventional fixed and advanced adaptive control system for resistance spot

    University essay from KTH/Industriell produktion

    Author : Caroline Bohlin; [2018]
    Keywords : RSW; Resistance spot welding; HCC; Heat Capacity Control; adaptivity; automotive;

    Abstract : Resistance spot welding is the main welding method used in the automotive industry to weld thin sheet metal. Today adaptive control systems have been developed for RSW, which means it can adjust the parameters in the weld process automatically during welding. READ MORE

  4. 18. Residual stresses in Ti-6Al-4V from low energy laser repair welding

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Peter Ericson; [2018]
    Keywords : Micro laser welding; Low energy welding; Ti-6Al-4V; Ti64; Residual stress; Response Surface Methodology; Repair welding; Welding simulation; Mikrolasersvetsning; Lågenergetisk svetsning; Lågenergisvets; Ti-6Al-4V; Ti64; Restspänningar; Response Surface Methodology; Reparationssvets; Svetssimulering;

    Abstract : Millimeterstora och svårupptäckta defekter kan uppstå internt i stora och komplexa gjutgods av Ti-6Al-4V, ibland går dessa oupptäckta tills detaljen genomgått mekanisk bearbetning och en stor kostnad redan har gått in i den. Dessa defekter och andra industriella olyckshändelser leder till ett behov av additiva reparationsmetoder där den för tillfället rådande metoden är TIG-svetsning. READ MORE

  5. 19. Numerical simulation of residual stresses in a weld seam : An application of the Finite Element Method

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Maciej Maczugowski; [2017]
    Keywords : Finite element method; residual stresses; temperature distribution; fatigue life; weld power; time step; T-joint weld model; Butt weld model.;

    Abstract : Articulated haulers are fundamental equipment to transport material. The load carrying structure on a hauler consists mainly of welded frames. During welding of the frames high residual stress will be introduced. These stresses may have a significant impact on the fatigue life of the frames. READ MORE

  6. 20. A Study in How Welding Parameters Affect the Porosity in Laser Welded High Pressure Die Cast AM50 Magnesium Alloy

    University essay from KTH/Materialvetenskap

    Author : Edwin Bergstedt; [2017]
    Keywords : Laser welding; AM50; Die Cast; Magnesium; Porosity;

    Abstract : There are a need for reducing the weight of vehicles, one solution is to implement cast lightweight materials such as the high pressure die cast AM50 magnesium alloy. The weldability of this cast alloy is poor and to implement the use of the alloy commercially a welding process is needed that limits the porosity of the weld. READ MORE
