Journal ArticleDOI
The prediction of seam welds quality in aluminum extrusion
Lorenzo Donati,Luca Tomesani +1 more
TL;DR: In this paper, a review and comparison of methods for evaluating the quality of seam welds in aluminum extruded profiles is presented, with the aim to evaluate the fields of pressure, flow stress and velocity on the welding surface.
Journal ArticleDOI
The influence of arc transfer mode in hybrid laser-mig welding
TL;DR: In this paper, the stability condition of a hybrid laser CO 2 -GMAW welding process was investigated by analyzing the influence of several process parameters, such as the filler metal transfer mode on the stability of the whole process.
Journal ArticleDOI
The effect of die design on the production and seam weld quality of extruded aluminum profiles
Lorenzo Donati,Luca Tomesani +1 more
TL;DR: In this article, an extensive investigation of the correlation between die design and the extrusion process of AA6082 aluminum alloy is presented, where a profile with a central seam weld line suitable for mechanical testing is extruded under different processing conditions, by varying the dimensions of the die feeder, the length of the welding chamber, the billet preheating temperature and the process speed.
Journal ArticleDOI
Characterization of seam weld quality in AA6082 extruded profiles
TL;DR: In this article, the performance of the extruded profile in subsequent manufacturing processes such as bending or forming is limited by the strength of the weakest weld, and the results were compared with unwelded profiles.
Journal ArticleDOI
Solid state bonding in extrusion and FSW: Process mechanics and analogies
TL;DR: In this paper, the solid state bonding occurring in extrusion and in friction stir welding (FSW) processes is investigated through FEM models previously developed and validated in particular for the AA6082-T6 aluminum alloys, such as strain, strain rate, effective stress and pressure.
