  1. 6. High Temperature Tribology in Hot Stamping

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Evan Kurnia; [2019]
    Keywords : high temperature tribology; hot stamping; acoustic emission; condition monitoring; hardfacing;

    Abstract : Many automotive components are made of Al-Si coated ultra-high strength boron steel (UHSS) and are produced by hot stamping process. In this process, the workpiece is heated to an austenitizing temperature and is then formed and quenched simultaneously between the tools to achieve the desired shape and high strength. READ MORE

  3. 7. 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

  4. 8. Modelling of the temperature field in TIG arc heat treated super duplex stainless steel samples

    University essay from Högskolan Väst/Avdelningen för maskinteknik och naturvetenskap

    Author : Chamara Kumara; [2016]
    Keywords : CFD modelling; Heat affected zone; OpenFOAM; Temperature field; TIG weld-ing; Phase transformation;

    Abstract : Super Duplex Stainless Steels have superior corrosion resistance properties and strength compared to conventional steels. However, these properties are influenced by the different phases that precipitate during the heat treatment process. READ MORE

  5. 9. 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.

  6. 10. MIG/MAG brazing with Cold Metal Transfer

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : MARIE ALLVAR; [2012]
    Keywords : CMT; Cold Metal Transfer; forceTIG; Plasmatron; brazing; arc brazing; laser brazing; automotive; zinc coated; galvanised; lap joint; CMT; Cold Metal Transfer; forceTIG; Plasmatron; lödning; båglödning; laserlödning; fordonsindustri; förzinkad; överlappsfog;

    Abstract : In the automotive industry a commonly used material is thin steel sheets coated with a thin layer of zinc for corrosion resistance purposes. Welding of this material, with the high temperatures involved, causes problems with zinc burn-off leading to reduced corrosion resistance. READ MORE
