  1. 1. Resistance Spot Welding of AlSi-coated Ultra High Strength Steel : An experimental study

    University essay from KTH/Materialvetenskap

    Author : Kristofer Hjelmtorp; [2019]
    Keywords : RSW; resistance spot welding; usibor; boron steel;

    Abstract : The automotive industry of today faces ever harder requirements from regulatory bodies to increase the fuel efficiency, reduce the carbon footprint and increase the safety of their vehicles. The problem is being tackled in different ways; one of them being the use of innovative materials to reduce the overall weight while improving the crash safety of the vehicle. READ MORE

  2. 2. Alloy 718 manufactured by AM Selective Laser Melting : Evaluation of microstructure and weldability

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

    Author : Valeri Ivanov Petkov; [2018]
    Keywords : Inconel 718; Selective Laser Melting; Additive Manufacturing; Heat Treatment; Weldability;

    Abstract : Inconel 718 is one of the main superalloys that are used in hot structures of jet engines today, because of its excellent mechanical properties at high temperatures and its good weldability. This material has been extensively used and studied in cast and wrought forms during the past decades. READ MORE

  3. 3. Residual Stresses Induced by Welding in High Performance Steel

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand; Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Rebecca Erlingsdotter Stridsman; Felicia Månsson; [2018]
    Keywords : Residual Stresses; High Performance Steel; Heat transfer; Abaqus; Welding;

    Abstract : Today, high performance steel as a construction material is treated as conventional steel in the European standards. Referring to the Eurocodes, the buckling curves for dimensioning of steel constructions only presents values up to steel grade S460, meaning that the full potential of high performance steel is not considered.

  4. 4. 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

  5. 5. Metallurgical investigation in weldability of Aluminium Silicon coated boron steel with different coating thickness.

    University essay from KTH/Materialvetenskap

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

    Abstract : 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. READ MORE
