Study of the Friction Stir Welding For A516 Low Carbon Steel

The main objective of present work is to describe the feasibility friction stir welding (FSW) forjoining low carbon steel with dimensions (3 mm X 80 150 mm). A matrix (3×3) weldingparameters (welding speed and tool rotational speed) was used see influence each parameter onproperties welded joint .Series experiments were conducted using CNC milling machineutilizing wide range transverse machine. Effect on mechanical properties weld joints investigated different testsincluding (tensile microhardness tests ). Micro structural change during process wasstudied zones optical microscope. weldingexperiments that show can be withmaximum efficiency (100.02%) in terms ultimate tensile strength best result ofwelding parameters (700 RPM, 25 mm/min, respectively and0.2 plunging depth tool) ,there afirst time we obtain reach to100.02 % this type by FSW. corrosion resistance measure whichis new test way obtained from ontraditional processes for thiswelding plate better than base metal. Maximum temperature has been calculated numerically byusing ANSYS program. peak 1102°C, percentage minimum themelting point .
