  1. 6. 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.

  4. 8. Offline study of next generation EUV pellicle materials and performances : From experimental design to material characterization

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Susanna Licheri; [2019]
    Keywords : Semiconductors; Nanotechnology; EUV Lithography; EUV Pellicle; Qualification study; Halvledare; nanoteknik; EUV litografi; EUV Pellicle; kvalificerings studie;

    Abstract : Lithography is the most crucial step in the semiconductor microfabrication workflow. Continuous features size shrinking co-occurs with the reduction of the exposure wavelength: a move from 193 nm light to extreme ultra-violet (EUV) at 13.5 nm is performed. The change poses a vast number of challenges that have been overcome in the past years. READ MORE

  5. 9. Characterization of Stainless Steel Welding Fume Particles : Influence of Stainless Steel Grade, Welding Parameters and Particle Size

    University essay from KTH/Materialvetenskap

    Author : Nanxuan Mei; [2016]
    Keywords : welding fume; stainless steel; chromium; manganese; particles;

    Abstract : Welding is a widely used method to join two pieces of stainless steel. Since it produces a large amount of fume during the process, it can cause adverse health effects. The welding fume particles contain many elements. Among them Cr, Mn and Ni are of concern. READ MORE

  6. 10. Improved inert gas protection - for laser weld and metal deposition processes

    University essay from KTH/Industriell produktion

    Author : Andreas Grindeland; [2011]
    Keywords : ;

    Abstract : The purpose of this thesis was to create a requirement specification for a shielding gas chamber for laser welding and/or laser metal deposition. This to improve the understanding of requirements that are needed for a chamber being able to be used in full production at Volvo Aero, Trollhättan. READ MORE
