DP780 steel sheets consisting of ferrite and martensite were successfully friction stir spot welded (FSSW) at the rotation rates of 500 to 1500 r/min using a W-Re alloy tool.
A plurality of steel plates including at least one first non-coated steel plate (W1) and at least one metal-coated steel plate (W2) are prepared. The plurality of steel plates are overlaid in such a fashion that at least one of the two steel plates located on the respective sides in the overlaying direction is the first non-coated steel plate. Effect of Welding Current on Weld Formation During resistance spot welding, the welding current is the most important process parameter, which determines the welding heat input and then has a great influence on the welding quality. In present study, the CR590T/340YDP galvanized dual phase steel widely used as automobile material was carried out using resistance spot welding. The effect of welding current on the weld
This paper studies a friction stir spot welding (FSSW) process that has been successfully applied to join aluminum alloy 6061-T6 to transformation-induced plasticity steel (TRIP) 780/800 steel. Cross sections of weld specimens show the formation of a hook with a swirling structure. Friction Stir Resistance Spot Welding of Aluminum Alloy Aug 22, 2018 · Merklein and Giera applied laser-assisted friction stir welding to weld deep drawing steel DC04 and the aluminum alloy AA6016-T4. With the application of the laser, the welding feed speed increased up to 2000 mm/min and the welded tensile strength reached 80% of the aluminum base material.

3.1 Friction stir keyholeless spot welded joints To investigate weld formation in friction stir keyholeless welding (FSKSW) of 3 mm thick AZ31 Mg alloy1 mm thick galvanized mild steel, a design-of- experiments (DOE) was performed , as listed in Table 3. For the purpose of comparison, friction stir spot welding Friction stir spot welding of DP1200 steel - ScienceDirectJan 01, 2013 · Friction stir spot welds were performed in an overlap configuration using 2 strips of 40x100 mm 2 with an overlap distance of 40 mm. Welding tests were carried out in a I-STIR PDS friction stir welding process development system under different welding parameters. Thus rotational speed, dwell time and plunging depth have been varied as shown in Table 1 so that 8 different welding
May 01, 2019 · 1. Introduction. The friction stir spot welding (FSSW) technique was invented by the Mazda Motor Corporation and Kawasaki Heavy Company in 2000 as a variant of the linear FSW method , which can be used to weld not only Al alloys but also high melting materials like steels [, , ].Shortly after the invention, FSSW was developed very quickly and its applications Generating Lap Joints Via Friction Stir Spot Welding on Piccini, J. M., Svoboda, H. G. Effect of pin length on Friction Stir Spot Welding (FSSW) of dissimilar Aluminum-steel joints. Procedia Materials Science . 9 , 504-513 (2015).
Dec 11, 2019 · However, the coating layer often influences the properties of the welds. In this study, friction stir spot welding (FSSW) is used to weld dissimilar metals, i.e., an Al alloy and AlSi-coated HPF steel. The effects of AlSi coating on the mechanical and metallurgical properties of the hook formation on the weld are investigated. Improving the joint strength of the friction stir spot Dec 06, 2018 · The purpose of this paper is to optimize the welding parameters:rotating speed and plunging depth of carbon steel and pure copper joints using friction stir spot welding (FSSW) with the aid of the design of experiments (DOE) method.,Carbon steel and pure copper sheets were welded using the FSSW technique with a cylindrical tool and without a probe.
