Journal ArticleDOI
Thin sheet welding of Al 6082 alloy by AC pulse-GMA and AC wave pulse-GMA welding
TL;DR: In this paper, an investigation on microstructure, weld bead geometry, dilution and mechanical properties of butt and overlap weld joints of thin aluminium sheets 1 mm of 6082 Al alloy produced by using AC P-GMA welding was carried out.
Journal ArticleDOI
Simulation of weld solidification microstructure and its coupling to the macroscopic heat and fluid flow modelling
Vitaliy Pavlyk,Ulrich Dilthey +1 more
TL;DR: In this article, the formation of a dendritic morphology during the directional solidification in gas-tungsten-arc welding is analyzed using a numerical macroscopic finite element modeling calculation of the weld pool fluid flow and temperature distribution.
Prospects by combining and coupling laser beam and arc welding processes

Journal ArticleDOI
Laser welding with filler wire
TL;DR: In this article, a process-internal signal, recorded by a sensor, helps to solve the problem of vertical distance variations between wire tip and weld pool, as this causes globular metal transfer and would result in strongly rippled, unclean welds.
Journal ArticleDOI
Welding of thin sheet of Al alloy (6082) by using Vario wire DC P-GMAW.
TL;DR: In this article, the micro-structure, weld bead geometry, dilution rate and mechanical properties of the butt and overlap weld joints of 1-mm-thick 6082 aluminium alloy sheet were investigated.
