23、EFACE This is Volume Three of the Eighth Edition of the Welding Handbook. The title of this third volume, Materials and ApplicationsPart 1, suggests correctly that the Eighth Edition will have a fourth volume, Materials and ApplicationsPart 2. Volume Three begins the process of updating and substant
24、ially expanding the material previously presented in Volume Four of the Seventh Edition and Volume 5 of the Sixth Edition. Originally, the Welding Handbook Committee had planned to publish the Materials and Applications title as a single publication. However, as the Committee began to compile the te
25、xt, it became apparent that the material was too voluminous to be contained in a single text. Therefore, it was necessary to separate Materials and Applications into two volumes. Unfortunately, this decision was made after the first two volumes of the Eighth Edition had been published, and so the fr
26、ont matter in Volumes One and Two indicate Volume Three to be the Materials and Applications material in its entirety. Volume Three, Materials and ApplicationsPart 1, covers many nonferrous metals, plastics, composites, ceramics, and new specialized topics: maintenance and repair welding and underwa
27、ter welding and cutting. Volume Four, Materials and ApplicationsPart 2, will contain information mostly on ferrous materials, but it also will cover titanium, clad and dissimilar metals, tube-to- tubesheet welding, and the reactive, refractory, and precious metals and alloys. Volume Four, Materials
28、and ApplicationsPart 2, is scheduled to be published two years following the publication of Volume Three, Materials and ApplicationsPart 1. This volume represents a considerable expansion of the information on these topics contained in previous editions. As with the first two volumes of this Eighth
29、Edition, practical application data and color illustrations have been added. This volume, like the others, was a voluntary effort by the Welding Handbook Committee and the Chapter Committees. The Chapter Committee Members and the Welding Handbook Committee Member responsible for each chapter are rec
30、ognized on the title page of that chapter. Other individuals also contributed in a variety of ways, particularly in chapter reviews. All participants contributed generously of their time and talent, and the American Welding Society expresses its sincere appreciation to them and to their employers fo
31、r supporting this work. The Welding Handbook Committee expresses its appreciation to the AWS staff members who assisted with this volume, especially the Technical Division staff engineers for technical assistance, Deborah Givens for editorial assistance, and Doreen Kubish for editorial and productio
32、n assistance with text, graphics, and layout. The Welding Handbook Committee welcomes your comments on the Welding Handbook as well as your potential interest in contributing to future volumes.

37、 IS JOINED with most of the known joining processes. It is readily joined by welding, braz- ing, soldering, adhesive bonding, or mechanical fasten- ing. In many instances, aluminum is joined by the conventional equipment and techniques used with other metals. Occasionally, specialized equipment or t
38、echniques, or both, are required. The alloy, joint con- figuration, strength requirement, appearance, and cost are factors that dictate the choice of joining process. Each process for joining aluminum has certain advan- tages and limitations. GENERAL CHARACTERISTICS OF ALUMINUM ALUMINUM IS LIGHT in
39、weight, yet some of its alloys have strengths exceeding mild steel. It retains good ductility at subzero temperatures, has high resis- tance to corrosion, and is not toxic. Aluminum has good electrical and thermal conductivity as well as high reflectivity to both heat and light. It is nonsparking an
40、d nonmagnetic. Aluminum is easy to fabricate. It can be cast, rolled, stamped, drawn, spun, stretched, or roll-formed. It can also be hammered, forged, or extruded into a wide vari- ety of shapes. Machining ease and speed are important factors in using aluminum parts. Aluminum can be given a wide va
41、riety of mechanical, electromechanical, chemical, or paint finishes. Pure aluminum melts at 1220 F (660 C). Alumi- num alloys have an approximate melting range of from 900 to 1220 F (482 to 660 C), depending upon the alloy. There is no color change in aluminum when heated to the welding or brazing t
42、emperature range. This necessitates a welder assuming a position where the melting of the base and filler metals under the arc or flame can be witnessed. High thermal conductivity (as compared to steel) necessitates a high rate of heat input for fusion welding. Thick sections may require preheating.
43、 When resistance spot welding, aluminums high thermal and electrical conductivities require higher current, shorter weld time, and more precise control of the welding variables than when welding steel. Since aluminum is nonmagnetic and no arc blow is experienced when welding with direct current, alu
44、mi- num is being used for backing and fixtures in welding. Aluminum and its alloys rapidly develop a tenacious, refractory oxide film when exposed to air. This naturalALUMINUM AND ALUMINUM ALLOYS oxide film can be removed using either a protective atmosphere or fluxes suitable during arc welding, br
45、az- ing, or soldering. Exposure to the elevated temperatures of thermal treatments or exposure to moist environ- ments cause the aluminum oxide film to markedly thicken, necessitating removal prior to joining. Heat-treated aluminum can have an exceptionally thick aluminum oxide film that causes poor
46、 wetting and flow of filler metal. Aluminum oxide melts at about 3700 F (2037 C) and should be removed by chemical or mechanical means prior to welding. The composition and melting range of an aluminum alloy are the pri- mary considerations for selection of the joining process. Anodic electrolytic t
47、reatments applied to aluminum result in forming thick, dense oxide coatings that must be removed prior to fusion welding, brazing or solder- ing. The anodic coatings can resist 400 volts or more, so welding arcs cannot be initiated. This oxide must be removed not only from the joint but also at the
48、location of the work lead when arc welding. The properties and performances of aluminum parts are influenced by microstructural changes that occur during any elevated-temperature joining process. The strength, fatigue life, ductility, and formability originally in the parts are changed depending upo
49、n the amount of annealing, overaging, and formation of cast structure occurring during the joining process. The results of these changes are presented in subsequent sections of this chapter devoted to specific joining processes. ALUMINUM FORMS PURE ALUMINUM IS readily alloyed with many other metals to produce a wide range of physical and mechanical properties. Table 1.1 lists the major alloy- ing elements in the wrought aluminum alloys. The means by which the alloying elements strengthen aluminum are used as the basis to classify aluminum alloys into two categories: nonheat-trea
