The relative motion between the tool and the substr AbstractThis paper reports the tensile fracture location characterizations of dissimilar friction stir welds
Friction Stir Welding Solheim Manufacturing Science The presence of different materials is vividly visible in the macrographs of dissimilar alloys FSW butt welds. For better understanding the materials transport will be studied by the aid of scanning electron microscope (SEM) equipped with Energy-dispersive X-ray spectroscopy (EDX). The ability to produce near net shape components, with tailored characteristics to meet durability and damage tolerance requirement, is one of the profound features of friction stir welding
The welded plates displayed an ultimate tensile strength of about 389 MPa, which lies between the ultimate tensile strength of St37 and St52 steels, 373 and 526 MPa, respectively. Moreover, the yield strength of the dissimilar joint was found to be about 272

Dec 01, 2012 · In the present study, 3 mm-thick plates of 304 stainless steel and st37 steel were welded together by friction stir welding at a welding speed of 50 mm/min and tool rotational speed of 400 and 800 rpm.X-ray diffraction test was carried out to study the phases which might be formed in the welds. Metallographic examinations, and tensile and microhardness tests were used to analyze the
Microstructure and Mechanical Properties of Dissimilar May 01, 2017 · In the present study, St37 low-carbon steel and 304 stainless steel were welded successfully, with the thickness of 2 mm, by a friction stir spot welding process carried out at the tool dwell time of 6 s and two different tool rotational speeds of 630 and 1250 rpm.
Microstructure, mechanical properties and microtexture of Friction stir welding is an efficient manufacturing method for joining dissimilar alloys, which can dramatically reduce grain sizes and offer high mechanical joint efficiency. Lap FSW joints between dissimilar AZ31B and Al 6061 alloy sheets were made at various tool rotation and travel speeds.
A friction stir welding tool and process for lap welding dissimilar materials are detailed. The invention includes a cutter scribe that penetrates and extrudes a first material of a lap weld stack to a preselected depth and further cuts a second material to provide a beneficial geometry defined by a plurality of mechanically interlocking features.Characterizations of dissimilar friction welding of ST37 Download PDF:Sorry, we are unable to provide the full text but you may find it at the following location(s):http://link.springer/conte (external link)
