This book was released on 2018-01-11 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust. Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials Welding plays a crucial role or say as a back bone of manufacturing industry to join the components. Friction stir welding (FSW) is a relatively new joining process that has been demonstrated in a variety of metals such as steel, titanium, lead, copper and aluminium. The unique properties of friction stir welds make possible some completely new structural designs with significant impact to ship design and construction. Friction stir welding is especially advantageous for joining aluminium and has been exploited commercially around the world in several industries. In the present work the effects of welding speed have been investigated on the microstructural and mechanical properties of friction stir welded aluminium alloy 6063. FSW was carried out at rotational speed of 1300 rpm (constant) and transverse speeds of 35, 50 and 65 mm/min. Mechanical performance has been investigated in terms of hardness, wear resistance and tensile strength. To study the effect of post welding heat treatment on properties of friction stir welded joint, the artificial ageing was carried out at 1600 C for a soaking period of 20 hours in the muffle furnace. The study revealed that friction stir welded joint prepared at welding speed of 35 mm/min exhibited better tensile strength, hardness and wear resistance. Better mechanical properties of the joint prepared at welding speed of 35 mm/min may be attributed due to fine, homogeneous and equaxed grain structure of stir zone. Post welding heat treatment of friction stir welded joint improved the wear resistance and microhardness of the joint. However tensile properties deteriorated with the post welding heat treatment of joint.

This book was released on 1963 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation was designed to show the effect of the following variables on the mechanical properties of heat treated low alloy steel repair welded without subsequent re-heat treatment: (1) Base metal composition and thickness; (2) percent penetration of repair; (3) repair welding filler composition; (4) weld composition being repaired; and (5) heat treat level of the base metal. The heat treat level or percent penetration ranges considered had little effect. With the use of a sufficiently strong repair weld filler, the failures occurred in the heat affected zone of the base metal. Variation of gage had a sizeable effect. The 4340 steel with deep hardening characteristics showed higher ''as repaired'' properties than 4130 steel. All the chosen fillers air hardened more readily than the base metal, hence their effect was small. (Author).

Download or read book Evaluation of Heat Affected Zone and Weld Metal Toughness in Selected Steels, Phase II written by and published by . This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume I reports on an assessment of a series of submerged arc welds prepared using 2 different wire-flux combinations giving weld metals alloyed with Ti-B, and Mo respectively and using different procedural variables such as heat input, post weld heat treatment, interpass temperature and joint restraint. Volume 2 explains the CVN and CTOD toughness of 4 gas metal arc welds prepared using Argon-5% carbon dioxide shielding gas and 3 consumable wires giving weld deposits alloyed with Mn-Mo, Mn-Si, and Ti-B respectively. All welds were made at 3.0 kJ/mm heat input, and the one with Ti-B weld metal was examined in the stress relieved condition also. The welds were examined for composition, strength, microstructure and inclusion distributions. Volume 3 examines a series of 14 welded assemblies prepared using the gas shielded flux cored arc welding process to examine the effect of welding procedural variables on weld metal toughness. All the welds were made using one of 3 different commercially available consumables and the Ar-25% CO2 gas shielding. Procedural variables studied included heat input, post weld heat treatment, and welding position lateral joint restraint. Their influence was assessed by microstructure characterization, deposit composition, CVN and CTOD toughness.

Book Synopsis Process Variables And Post Weld Heat Treatment Effects On Steel Weld by : Oluyemi Olawale
Download or read book Process Variables And Post Weld Heat Treatment Effects On Steel Weld written by Oluyemi Olawale and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents the outcome of our investigation that was conducted to correlate process variables in shielded metal-arc welding and post weld heat treatment on some mechanical properties of low carbon steel weld. From the results obtained we observed that welding current and post weld heat treatment temperatures influences the tensile strength, impact strength and hardness of welded low carbon steel. As the welding current increases the hardness and strength increases but impact strength reduces, while hardness and strength continuously reduces but impact strength increases as post weld heat treatment temperatures increases. This outcome will help to eliminate much of the "guess work" often employed by welders to specify welding parameters and help them to properly select them for a given task to provide a good weld quality. With this finding welder can now adequately select welding currents and post weld heat treatment temperatures for low carbon steel that will yield quality weld in shielded metal-arc welding without guess work.
