  1. 1. Investigating Primer Effects on Top Coat Structure : A Study Made at Volvo GTO, Umeå

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Johan Fors; [2020]
    Keywords : ;

    Abstract : Quality control is an integral part in all production industry. One important part of this control is the examination of the surface structure. This is especially important in automotive industries where the visual appearance is a big part of the general perception of quality for the customer. READ MORE

  2. 2. The effect of printing parameters on the deformation and microstructure of Inconel 718 : A study in pulsed laser and powder based directed energy deposition additive manufacturing

    University essay from KTH/Materialvetenskap

    Author : Elias Repper; [2020]
    Keywords : Laser; Additive Manufacturing; Metal; Deposition; Quasi-continuous-wave; Pulsed; Ni-base superalloy; Laves; Deformation; Residual stresses;

    Abstract : Additive manufacturing has the power to redefine how we create components. In order to minimize removal of printed material, deformation must be kept a minimum. When deposition rate is increased during directed energy deposition so is the power requirement for melting the feedstock. READ MORE

  3. 3. Traceability of Human Error Production Defects in Automotive Manufacturing

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Chiara Lucatello; Chatchai Sornkarn; [2019-11-12]
    Keywords : Error detection; in-and-out; logging process; Inputting process; Technological frames; Usability; Traceability; Process improvement; Factory automation;

    Abstract : Many global automotive industries have movedtowards factory automation, yet several still rely on collectingmanual data from the plant floor and manually inputting thedata into the management quality system in the assembly line. Inthis case study research, the objective of our study was to observehow technology advancement can be supported for human errorlogging in the quality assurance process. READ MORE

  4. 4. EB-PBF additive manufacturing of Alloy 718 : Effect of shot peening on surface characteristics and high temperature corrosion performance

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik
