“…Hard and brittle precipitates occur at the weld bead due to the difference in peak temperature of UFSW compared to air friction stir welding (AFSW), making it more problematic. [5][6]. A curved interface forms due to increased materials mixing at the advancing side, resulting in a linear hardness gradient across the dissimilar weldment.…”

This work focuses on optimizing process parameters in underwater friction stir welding to study their impact on the mechanical characteristics of aluminum 2014 T6 and 6082 T6 joints. The aluminum plates are precisely machined to provide the necessary polish for the underwater friction stir welding process (UFSW). Experiments are designed using Taguchi L-9 orthogonal array, considering three process parameters: speed, transverse speed, and tool angles at three levels each. The aluminum plates of series 2014-T6 and 6082-T6 are securely installed in the machine. The plates will be welded using the UFSW process using a taper pin tool. The welded plates are next subjected to tests to assess their mechanical qualities. Tests for tensile strength, hardness, and impact strength are conducted on the welded area of the plate to determine its mechanical qualities. An ANOVA was conducted to determine the significant influence of each variable. The optimal values achieved are Tensile Strength of 185.592 N/mm2, Hardness of 75.1 (BHN), and Impact Strength of 21.236 Joules at a speed of 1120 rpm, transverse speed of 80 mm/min, and tilt angle of 2 degrees.

“…Research on FSW and SFSW welding are in a continuous dynamic on an international level and aims to analyze the possibilities of application to different types of metal materials used in the mentioned top industrial fields, such as e.g. aluminum alloys, but also magnesium alloys, steels and copper alloys [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. FSW welding in liquid working environment is indicated for materials where plasticization occurs at moderate temperatures but plasticization can become excessive in a short time (e.g.…”

Friction stir welding is an important topic within ISIM Timisoara, with several research projects being implemented in this field. Friction stir welding in liquid working environment aims to avoid overheating of the welding tool and device during the joining process and achieve better results compared to FSW welding in ambient environment. The paper presents results obtained by ISIM Timisoara in the framework of a national research project (in progress), regarding the friction stir welding in liquid environment (SFSW) of the EN AW 1200 aluminum alloy. The experimental research aimed at an analysis of the SFSW welded joints for the EN AW 1200 aluminum alloy, made with four different welding tool geometries, under the same working conditions regarding the FSW welding machine and the technological process parameters.
