  1. 1. Design Study of Welded Beam Bracket According to Stress Concentrations in the Weld

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FREDRIK EKLUND; [2021]
    Nyckelord :Plug weld; slot weld; welded beam; welded beam bracket; welded bus chassis; Pluggsvets; svetsad balk; svetsad busschassi; svetsad ram;

    Sammanfattning : In a bus chassis, welded connections are often preferred to other fastening techniques due to low cost and broad competence among suppliers but are usually the weakest parts due to fatigue life. Evaluation of welds is often costly in time and competence. LÄS MER

  3. 2. Researching and Developing Universal Gas Purging Solutions

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

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

    Sammanfattning : 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. 3. Metallurgical investigation in weldability of Aluminium Silicon coated boron steel with different coating thickness.

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Rickard Aldén; [2015]
    Nyckelord :boron steel; AlSi coating; weldability; hot stamping; phase formation;

    Sammanfattning : Hot-pressed aluminium and silicon coated boron steel is used in the car industry where high tensile strength is of great importance, such as in the safety cage of a car where deformation has to be kept to a minimum in case of a collision. After hot-pressing the AlSi-boron steel shows excellent properties with high tensile strength, minimal spring back and also shows good protection against corrosion. LÄS MER
