1. 1. Sample quality effects of laser cutting : An empirical study on the heat affected zone and the surface quality in laser cut samples

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Emma Bevin; Matilda Björklund; [2020]
   Nyckelord :Laser cutting; Laser cutting quality; Heat affected zone; Surface quality; Surface angularity; Laserskärning; Laserskärnings-kvalité; Värmepåverkad zon; Ytkvalité; Ytvinkel;

   Sammanfattning : This study has been conducted with the aim to examine the extent of the heat affected zone in order to use laser cutting when making samples for tensile testing. When cutting with a laser the material absorbs heat energy from the laser beams which causes changes in the microstructure. LÄS MER

   Magister-uppsats, Institutionen för teknikvetenskaper

   Författare :Marina Malmberg; [2013]
   Nyckelord :Laser; laserskärning; dragprov; dragprovstav; slagprov; slagprovstav; värmepåverkan; hårdhet;

   Sammanfattning : An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. LÄS MER
