Book excerpt: This publication is a comprehensive book on the welding of aluminium, aimed primarily at practising engineers and students of welding technology. After describing the properties of wrought and cast aluminium alloys, their applications, alloy designations and composition, both in heat-treatable and non heat-treatable alloys, it goes on to explain the process variables in weld metal transfer mechanisms, the ways of overcoming problems in GAS tungsten ARC welding, and distortion - also providing numerical methods of analysis. A thorough and timely guide to all aspects of aluminium welding.
Download or read book The effect of welding parameters on mechanical properties and microstructural behaviour of Al Alloy 6061 using TIG written by Vishavdeep Singh and published by BookRix. This book was released on 2018-02-27 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated tungsten inert gas welding process involves a method of increasing penetration capability of the arc in TIG welding. This is achieved through the application of a thin coating of activated flux onto the joint surface prior to welding. This leads to strong joint. This paper deals with the study of microstructural and mechanical properties of aluminium alloy AA-6061 weld joints using A-TIG welding. During the experiment the welding current and gas flow rate are used as variable parameters and welding speed kept as constant. In this activated TIG welding process, there were five single component fluxes which are CdCl2, SiO2, MgO, Al2O3 and TiO2 used in the initial experiment to evaluate Welding current, Gas Flow Rate, Flux by joining plates by using A-TIG welds. Based on the higher penetration of weld bead, two single component fluxes SiO2 and TiO2 were selected for actual experiment. The values of optimum welding current and gas flow rate and flux was finding out from the experiment. Welding specimen were investigated using scanning electron microscope, vicker's micro hardness test and tensile strength. The SiO2 flux produced the most noticeable effect in terms of tensile strength and micro hardness.
Download or read book Investigation on the Welding of High Strength Aluminum Alloys written by and published by . This book was released on 1949 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program was to develop methods for improving the strengths of joints in high-strength aluminum alloys. Details of the work during the period May 1, 1949, to October 31, 1949, are also presented. The all-weld-metal strength properties and the aging characteristics were determined for welds made between copper dams and in alloy base plates with aluminum-magnesium alloys containing from 5 to 15 per cent magnesium. Transverse tensile tests of joints made in 61S-T6, 24S-T4, and 75S-T6 plates with these alloys were also carried out. Some cold-welding tests were made. The major effort during the third contract period was devoted to testing two series of aluminum-alloy filler metals. One of these series was based on the Frontier 40E composition (5.5% Zn, 0.5% Mg, 0.2% Ti, 0.5% Cr), the other was a series of aluminum-magnesium alloys covering the range from 5 to 15 per cent magnesium.

Download or read book The Welding of Aluminium and Its Alloys written by G Mathers and published by Elsevier. This book was released on 2002-09-24 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Welding of Aluminium and its Alloys is a practical user's guide to all aspects of welding aluminium and aluminium alloys. It provides a basic understanding of the metallurgical principles involved showing how alloys achieve their strength and how the process of welding can affect these properties. The book is intended to provide engineers with perhaps little prior understanding of metallurgy and only a brief acquaintance with the welding processes involved with a concise and effective reference to the subject.It is intended as a practical guide for the Welding Engineer and covers weldability of aluminium alloys; process descriptions, advantages, limitations, proposed weld parameters, health and safety issues; preparation for welding, quality assurance and quality control issues along with problem solving.The book includes sections on parent metal storage and preparation prior to welding. It describes the more frequently encountered processes and has recommendations on welding parameters that may be used as a starting point for the development of a viable welding procedure. Included in these chapters are hints and tips to avoid some of the pitfalls of welding these sometimes-problematic materials. The content is both descriptive and qualitative. The author has avoided the use of mathematical expressions to describe the effects of welding.This book is essential reading for welding engineers, production engineers, production managers, designers and shop-floor supervisors involved in the aluminium fabrication industry. A practical user's guide by a respected expert to all aspects of welding of aluminium Designed to be easily understood by the non-metallurgist whilst covering the most necessary metallurgical aspects Demonstrates best practice in fabricating aluminium structures
Download or read book Influence of Welding and Heat Treatment on Aluminum Alloys written by Eric B. Hilty and published by . This book was released on 2014 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The welding of structural materials, such as aluminum alloys 6063, 6061 and 6005A, does have an adverse influence on the microstructure and mechanical properties at locations immediately adjacent to the weld. The influence of heat input, due to welding and artificial aging, was investigated on aluminum alloy extrusions of 6063, 6061 and 6005A. Uniaxial tensile tests, in conjunction with scanning electron microscopy observations, were done on the: (i) as-provided alloy in the natural temper, (ii) the as-provided alloy artificially aged, (iii) the as-welded alloy in the natural temper, and (iv) the as-welded alloy subject to heat treatment. The welding process used was gas metal arc (GMAW) with spray transfer at approximately 140-220 amps of current at 22-26 volts. The artificial aging used was a precipitation heat treatment for 6 hours at 360oF. The aluminum alloys of the 6XXX series contain magnesium (Mg) and silicone (Si) and are responsive to temperature. Optical microscopy observations revealed the influence of artificial aging to cause change in both size and shape of the second-phase particles present and distributed through the microstructure. The temperature and time of exposure to heat treatment did cause the second-phase particles to both precipitate and migrate through the microstructure resulting in an observable change in strength of the material. Uniaxial tensile tests were conducted for desired specimen thicknesses for sake of comparison. Section 6.4.2-2 of the 2010 Aluminum Design manual discusses provisions for mechanical properties of welded and artificially aged aluminum light poles, fabricated from aluminum alloy 6063 and 6005A. A basis for these provisions was the result of older round-robin testing programs [2, 3]. However, results of the studies were never placed in the open literature. Hence, the focus of this study was to determine the expected mechanical properties of welded and artificially aged 6063, 6061 and 6005A aluminum alloys and publish the results. Tensile tests revealed the welded aluminum alloy to have lower strength, both yield and ultimate tensile strength, when compared to the as-received un-welded counterpart. The impact of post-weld heat treatment on tensile properties and resultant fracture behavior is presented and briefly discussed in light of intrinsic microstructural effects and nature of loading.
Download or read book The Effect of Preheating and Postheating on the Quality of Spot Welds in Aluminum Alloys written by Wendell Frederick Hess and published by . This book was released on 1947 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of tests show that a slowly rising condenser-discharge preheat current with a rapidly rising welding current afford no less expulsion than a rapidly rising welding current alone, and was inferior to a slowly rising welding current alone. In one case using slowly rising current for preheating and welding proved beneficial although generally, utilizing a raised electrode welding force to decrease expulsion was more practicable. Postheating had no effect on sheart strength until the current sufficient to remelt the welds, which greatly increased the weld diameter and shear strength.
