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 mass saving potential of light-weight materials, such as Al alloys, is beneficial for fuel economy and reducing CO 2 emissions. However, the wide-spread use of these alloys has been long hindered due to the difficulty in fusion joining as well as their high cost. Welding of Al alloys, which are considered to be difficult to weld through conventional arc welding, is now possible by either of low heat input arc welding, high-power density fusion joining, such as laser beam welding and electron beam welding, or friction stir welding. Particularly, friction stir welding can be successfully applied to these materials owing to the fact that no melting takes place in the weld nugget. The aim of this overview is to summarize the developments in the joining of Al alloys over the recent years. This study is also intended to provide guidance for the industry and researchers dealing with joining of these alloys.

Aluminium and its alloys are used in fabrications because of their low weight, good corrosion resistance and weldability. Although normally low strength, some of the more complex alloys can have mechanical properties equivalent to steels. The various types of aluminium alloy are identified and guidance is given on fabricating components without impairing corrosion and mechanical properties of the material or introducing imperfections into the weld. As pure aluminium is relatively soft, small amounts of alloying elements are added to produce a range of mechanical properties. The alloys are grouped according to the principal alloying elements, specific commercial alloys have a four-digit designation according to the international specifications for wrought alloys or the ISO alpha - numeric system. The alloys can be further classified according to the means by which the alloying elements develop mechanical properties, non-heat-treatable or heat-treatable alloys.
Aluminium alloys or aluminum alloys ; see spelling differences are alloys in which aluminium Al is the predominant metal. The typical alloying elements are copper , magnesium , manganese , silicon , tin and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al—Si , where the high levels of silicon 4. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required. Alloys composed mostly of aluminium have been very important in aerospace manufacturing since the introduction of metal-skinned aircraft.
Weldability is a function of three major factors: base material quality, welding process, and design. This article focuses on base-metal weldability of aluminum alloys in terms of mechanical property degradation in both the weld region and heat-affected zone, weld porosity, and susceptibility to solidification cracking and liquation cracking. It provides an overview on welding processes, including gas metal arc welding, gas tungsten arc welding, resistance spot and seam welding, laser beam welding, and various solid-state welding processes. A review on joint design is also included, mainly in the general factors associated with service weldability fitness. The article also provides a discussion on the selection and weldability of non-heat-treatable aluminum alloys, heat treatable aluminum alloys, aluminum-lithium alloys, and aluminum metal-matrix composites.

И ради этого стоило убивать. Когда Беккер наконец вышел из Гиральды в Апельсиновый сад, утреннее солнце уже нещадно пекло. Боль в боку немного утихла, да и глаза как будто обрели прежнюю зоркость. Он немного постоял, наслаждаясь ярким солнцем и тонким ароматом цветущих апельсиновых деревьев, а потом медленно зашагал к выходу на площадь. В этот момент рядом резко притормозил мини-автобус.
Беккер встал и бесцельно побрел по калле Делисиас, раздумывая на ходу, что бы предпринять. Мощенный брусчаткой тротуар под ногами постепенно сливался в одну темную гладкую полосу. Быстро опускалась ночь.
Фонтейн долго молчал. Потом, тяжело вздохнув, скомандовал: - Хорошо. Запускайте видеозапись. ГЛАВА 117 - Трансляция видеофильма начнется через десять секунд, - возвестил трескучий голос агента Смита. - Мы опустим каждый второй кадр вместе со звуковым сопровождением и постараемся держаться как можно ближе к реальному времени. На подиуме все замолчали, не отрывая глаз от экрана.
Но колокольный звон растекался по улочке, призывая людей выйти из своих домов. Появилась вторая пара, с детьми, и шумно приветствовала соседей. Они болтали, смеялись и троекратно целовали друг друга в щеки.
