· When welding Al 7075-T651, close values were obtained except for the size that defines the wear of the front surface of the shoulder of the welding tool.
The high degree of wear can be attributed to: - large friction surface between the tool shoulder and the welding materials (~ 351mm2) - high pressure of the plastified material moving during the process - high hardness of Al 7075-T651 alloy (160-180HV).
· Following the tests on the durability of the tools, when welding Al 7075-T651, compared to Al 99.5, the tool with threaded cylindrical pin behaved well in terms of wear, but for the shoulder, if it is necessary to achieve considerable lengths of welded material (in industrial applications), it is recommended to use a stronger and harder material than X38CrMoV5 (AISI H11) - hardness 52-54 HRC, such as X40CrMoV5 (AISI H13) - hardness 63-66 HRC, X210Cr12 (AISI D3) - hardness 58-64HRC or X155CrVMo121 (AISI D2) - hardness 55-62 HRC

The simulation of the pearlite formation was performed by Nakajima et al. [11].
Steinbach et al. [12] extended this phase field approach considering the stress and strain.
The numerical formulation is based on the generalized multi-phase field (MPF) approach developed by Steinbach et al. [3-5] and is an extension of the phase field.

S.Valls et al. [7] revealed that dry sewage sludge could decrease the mechanical properties of concrete appreciably and most studies also reported a decrease of compressive strength of mortars and concrete when sewage sludge ash (SSA) was used as a cement [8, 9] or sand replacement [10].

Such alloy is a solid solution hardened Al–Mg alloy, offering moderate strength, typically used in engineering structural applications such as pressure vessels, tanks, fitting, boat hulls, and van bodies.
As far as the s-e curves obtained on the welds are compared with that of the base alloy, it can be seen that the tensile strength of the joints is systematically lower than that of the BM-H111, according to the results obtained by Simoncini and Forcellese on similar and dissimilar FSWed joints in AA5754 and AZ31 sheets [10] and by Wonoh et al. on five different sheets in 6111-T4, 5083-H18, 5083-O aluminum alloys, dual-phase steel and AZ31 magnesium alloy [11].
behaviour can be explained by taking into account the effect of the rotational speed and welding speed on temperature, heat generation and cooling, as also shown by Leal at al. [12] and Nandan et al. [13].
