CHARACTERIZATION AND PROCESSING OF FRICTION STIR WELDING ON COPPER WELDS

Abstract

FSW(Friction Stir Welding) is a welding technology will be a part of different metals with sensible properties. During this paper, fsw attachment b/n steel, aluminum and copper plates with thicknesses of 3 millimeter was welded. Here we tend to had considered completely different completely different} materials with different combinations i.e copper and copper, copper and aluminum, aluminum & stainless steel, stainless steel & copper. Friction Stir Welding experiments were employed to get the good wieldable properties by maintaining the rpm speeds to 1120 revolutions per minute and attachment speed within the limit of 14112 mm/min and here we can adjust the pin profile of the location respect to the line butt. Micro struc analysis can be done for examine the parent and the welded material. Cutting and sectioning of the welded pieces for metallographic analysis of the planes which are perpendicular for the attachment and the travelling direction & which is parallel to the friction welding was done. Here the mechanical properties of welding which was were determined by employing the same standard micro hardness and also tensile hardness testing and finding the maximum elongation of the metals to the properties of fsw. From experimental fsw process it can be found the pin profile and also the rotational speed, feed is an important in manufacturing of free welds in fsw of aluminum, copper and steel.
