1. 21. 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

3. 22. Evaluation of current welding robot and improvement proposals for future use

   University essay from KTH/Marina system

   Author : Joakim Nilsson; [2018]
   Keywords : ;

   Abstract : Welding of elements, a heat exchanging component, is one of the most essential processes during the manufacturing of Tubel evaporators. Weld joints consists of fillet welds of thin tubes against a plate on one end, and on the other end against a thicker pipe with entry holes for the tubes. READ MORE

4. 23. 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. 24. 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

6. 25. Overlay welding of FeCrAl alloys

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Lezan Rashid; [2016]
   Keywords : Overlay welding; FeCrAl; TIG; MIG; welding evaluation;

   Abstract : In this master thesis different overlay welding methods suitable for boiler application has been investigated. The purpose of this project is to define advantages and disadvantages for each overlay welding methods and suggest some evaluation criteria on some commercial and experimental alloys aimed for overlay welding material.
