Mechanical characterization of CO2 laser beam butt welds of AA5083

Influence of the silicon content on the mechanical properties of AA6xxx laser welds

“…Joint efficiencies around 80% have been obtained after laser welding on 7000 series (7075) [4]. Laser welding of Al-Mg alloys (5000 series) has been investigated and presents a fracture strength joint efficiency varying from 43% to 91%, depending on the process parameters used [6]. These results are in agreement with [7] on the 5754 alloy.…”

“…In fact, it is known that the hot cracking tendency for a binary aluminium alloy shows a maximum close to the solubility limit of the element and decreases rapidly beyond this limit [14,16,17]. However, it is important to note that all the studies cited there [5][6][7] have been carried out without the use of any filler wire and have been focused on the influence of the welding parameters (input power, welding speed, etc.). In the case of 6xxx series alloys, the usual filler wire is constituted of an Al-Si alloy with a low melting temperature such as 4047 (12%Si) or 4043 (5%Si).…”

Microstructure and mechanical properties of aluminum 5083 weldments by gas tungsten arc and gas metal arc welding

“…They have the virtue of being broadly used in nowadays HSTs in China for their well balanced strength, weldability, and formability in contrast to weldments of other types. Some structural and mechanical properties [4][5][6][7] of Al5083 and their weldments have been investigated [8][9][10][11][12][13]. For example, mechanical properties of Al5083 using semi-automatic and automatic pulsed gas metal arc welding were investigated, and it was reported that both welding methods cause considerable softening in the weldments.…”

The Effect of Process Parameters on the Microstructure and Mechanical Performance of Fiber Laser-Welded AA5182 Aluminium Alloys

“…The results indicated that weld penetration was increased significantly as the incident beam angle increased. Ancona et al [8] conducted laser butt welding of AA5083 aluminium alloy. They used the design of the experiment technique to investigate the effects of the variables on the mechanical properties and porosity level and stated that in terms of tensile load the best results were found for high powers and high welding speeds.…”
