In this study different tool shoulder plunge depth was applied on the work surface during friction stir welding of copper. The hardness and tensile strength of welded joints were investigated. The welded joint prepared with 0.3 tool plunge depth exhibited better tensile strength and hardness with good bead appearance. The tool pin wear was also analyzed with the multiple distance of welding. The understanding of the plunge depth and tool wear would be advantageous to estimate the tool pin profile shape and weld parameters during welding of copper.

“…The working principle of Friction stir welding and processing is explained elsewhere [6][7][8]. P. Sahlot et al, (2018) [9] studied the effect of tool rotational speed, tool traverse speed and tool traverse distance on tool wear of FSW of Copper. The maximum tool wear occurred on the tool tip and less wear was observed on the tool root.…”

The article discusses the basic issues related to the technology of friction stir welding (FSW). A short description of technology is provided. The following section provides the analysis of effect of technological parameters (tool rotation and welding speed) on the mechanical properties of the prepared joint (strength, ductility, microhardness). In both cases the analysis refers to aluminum alloys (6056 and AA2195-T0). The comparative analysis showed the phenomenon of the increase in weld strength along with the increase in the rotational speed of the tool during welding. Similarly, with the increase in welding speed, an increase in weld strength was observed. Some exceptions have been observed from the above relations, as described in the article. In addition, examples of material hardness distribution in the joint are presented, indicating their lack of symmetry, caused by the rotational movement of the tool. The analyses were performed basing on the literature data.

“…In published literature [20,52,54,55], it was reported that the tool wear rate decreased with an increase in traverse speed and decrease in tool rotational speed, which suggests that the tool life can be improved by adjusting the welding parameters. The relative hardness of the tool and workpiece material at welding temperature conditions significantly affected the tool wear [21,52]. The increase in rotational speed enhanced the relative velocity at the tool/workpiece interface [56,57], which resulted in the higher tool temperature.…”

“…During the joining of high-temperature/high-strength alloys like titanium, nickel and steels, the tool wear is an important issue [20]. The tool debris in weld nugget considerably influenced the mechanical properties of FS-welded joints [13,21,22]. Insufficient heat input may lead to wear of the tool pin due to lack of softening, which results in inadequate plastic deformation of the material [11].…”

In this research, numerical as well as experimental analysis on friction stir welding (FSW) of dissimilar steels, i.e. DH36 steel and AISI 1008 steel, was performed. A 3D heat transfer FE model based on Abaqus/CAE using Fortran code via DFLUX subroutine was developed to investigate the effect of FSW parameters (i.e. rotational speed and traverse speed) on temperature distribution during the welding. It was observed that decreasing the traverse speed, increasing the rotational speed and shoulder diameter enhanced the peak temperature due to higher heat input. Based on the experimentally obtained sound quality welding parameters, the FE model was successfully validated with a maximum percentage error of 5.57% for peak temperature. Experimental results revealed that the higher heat generation reduced the grain size by increasing the rotational speed and decreasing the traverse speed. The inhomogeneous hardness distribution was observed across the weld cross section due to grain size variation. The higher grain refinement at a rotational speed of 600 rpm with a traverse speed of 70 mm/min produced the maximum value of the hardness and impact toughness. The tensile weld samples were fractured in the base metal zone (i.e. AISI 1008 steel) and experienced the tensile strength within the range of the AISI 1008 steel. The microstructure in the SZ exhibited the Widmanstatten ferrite in AISI 1008 steel and acicular-shaped bainite ferrite in DH36 steel. EDS analysis of the fractured surface of impact specimens confirmed the embedment of tungsten carbide particles in the weld zone due to the tool wear.
