1. 1. Laser-arc hybrid welding of high strength steel : Weld quality and process stability

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

   Author : David Lohse; [2021]
   Keywords : Laser; arc; hybrid; welding; high; strength; steel; high-strength; HSLA; weld quality; process stability;

   Abstract : The development of high strength steel enables constructions to be made with less material than with previous used steel grades. The possibility of creating lightweight constructions with the same or even better mechanical properties is of high focus in the steel industry today. READ MORE

3. 2. Weld Quality in Aluminium Alloys

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Rujira Ninni Deekhunthod; [2014]
   Keywords : Weld Aluminium Alloys MIG MAG;

   Abstract : The aims of this project are to present an understanding in what happens when aluminium-(Al) alloys are welded, and to investigate how the Mg-, Si- and Cr-contents in AA6005A influence the weld strength and cracking susceptibility. It is known that heat from welding affects the mechanical properties (strength) of the material. READ MORE

4. 3. MIG/MAG brazing with Cold Metal Transfer

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : MARIE ALLVAR; [2012]
   Keywords : CMT; Cold Metal Transfer; forceTIG; Plasmatron; brazing; arc brazing; laser brazing; automotive; zinc coated; galvanised; lap joint; CMT; Cold Metal Transfer; forceTIG; Plasmatron; lödning; båglödning; laserlödning; fordonsindustri; förzinkad; överlappsfog;

   Abstract : In the automotive industry a commonly used material is thin steel sheets coated with a thin layer of zinc for corrosion resistance purposes. Welding of this material, with the high temperatures involved, causes problems with zinc burn-off leading to reduced corrosion resistance. READ MORE
