The Welding of Aluminium and Its Alloys (Woodhead Publishing Series in Welding and Other Joining Technologies)

The Welding of Aluminium and its Alloys provides a basic understanding of the metallurgic principles underpinning how alloys achieve their strength and how welding can effect their properties. A practical guide for the shop-floor engineer, the book covers weldability of aluminium alloys, process description, advantages, limitations, proposed weld parameters, health and safety issues, preparation for welding, quality assurance and quality control issues, and problem solving. The book covers parent metal storage and preparation prior to welding, describes the more frequently encountered processes, and presents recommendations on welding parameters that may be used as a starting point for the development of a viable welding procedure. Providing hints and tips that help you avoid some of the pitfalls of welding these sometimes problematic materials, the book's content is both descriptive and qualitative. The Welding of Aluminium and its Alloys is a concise and effective reference for engineers who may have little prior understanding of metallurgy and only a brief acquaintance with the welding processes involved. # Welding of Aluminum - Mathers.pdf......Page 1 Front Matter......Page 2 Preface......Page 5 Table of Contents......Page 0 Back Cover......Page 6 Table of Contents......Page 7 1.1 Introduction......Page 10 1.2 Characteristics of Aluminium......Page 13 1.4 Welding: A Few Definitions......Page 15 2.2 Strengthening Mechanisms......Page 19 2.3 Aluminium Weldability Problems......Page 27 2.4 Strength Loss Due to Welding......Page 40 3.2 Alloying Elements......Page 44 3.3 CEN Designation System......Page 45 3.4 Specific Alloy Metallurgy......Page 49 3.5 Filler Metal Selection......Page 55 4.2 Storage and Handling......Page 60 4.3 Plasma-Arc Cutting......Page 61 4.4 Laser Beam Cutting......Page 67 4.5 Water Jet Cutting......Page 72 4.6 Mechanical Cutting......Page 73 4.7 Cleaning and Degreasing......Page 75 5.1 Introduction......Page 78 5.2 Access for Welding......Page 79 5.3 Welding Speed......Page 80 5.5 Edge Preparation and Joint Design......Page 81 5.6 Distortion......Page 93 5.7 Rectification of Distortion......Page 97 5.8 Fatigue Strength of Welded Joints......Page 98 6.2 Process Principles......Page 106 6.3 Mechanised/Automatic Welding......Page 123 6.4 TIG Spot and Plug Welding......Page 124 7.2 Process Principles......Page 125 7.3 Welding Consumables......Page 139 7.4 Welding Procedures and Techniques......Page 144 7.5 Mechanised and Robotic Welding......Page 150 7.6 Mechanised Electro-Gas Welding......Page 152 7.7 MIG Spot Welding......Page 153 8.2 Plasma-Arc Welding......Page 156 8.3 Laser Welding......Page 159 8.4 Electron Beam Welding......Page 164 8.5 Friction Welding......Page 169 9.1 Introduction......Page 175 9.2 Power Sources......Page 176 9.3 Surface Condition and Preparation......Page 178 9.4 Spot Welding......Page 180 9.5 Seam Welding......Page 184 9.6 Flash Butt Welding......Page 185 10.2 Welding Procedures......Page 190 10.3 Welder Approval......Page 200 11.2 Defects in Arc Welding......Page 208 11.3 Non-Destructive Testing Methods......Page 214 Appendix A: British and ISO Standards Related to Welding and Aluminium......Page 225 Appendix B: Physical, Mechanical and Chemical Properties at 20°C......Page 235 Appendix C: Principal Alloy Designations: Cast Products......Page 236 Appendix D: Alloy Designations: Wrought Products......Page 237 Bibliography......Page 239 Index......Page 244 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
