Pipe Welding Procedures

A standard reference for decades, this new edition of Pipe Welding Procedures continues to reinforce the welder's understanding of procedures. Drawing on his extensive practical and teaching experience in the field, the author describes in detail the manipulating procedures used to weld pipe joints. You will find useful information on heat input and distribution, essentials of shielded metal-arc technology, distortion, pipe welding defects, welding safety, essentials of welding metallurgy, and qualification of the welding procedure and the welder.

Welding Practices and Procedures for the Pipe Trades focuses on welding equipment, welding practices and procedures, and testing used in the pipe trades. Based on selected content from the industry leading Welding Skills textbook, this helpful resource presents targeted topics including welding safety, shielded metal arc welding, gas tungsten arc welding, gas metal arc welding, and other welding and pipe joining processes. Weld evaluation, welding metallurgy, and related welding qualifications are also included. Detailed illustrations and step-by-step procedures throughout the book reinforce fundamental concepts and common applications.

The welding of tubes is an essential requirement in the fabrication of components in many industries. The original idea for this book came from a seminar organized by The Welding Institute which attracted over 100 specialists concerned with design, fabrication, production and quality assurance and yielded a number of valuable papers. "Process Pipe and Tube Welding" contains some of these papers together with additional chapters to provide comprehensive coverage of all aspects of tube welding from initial design considerations through production to final inspection. In the first three chapters the authors outline the process and equipment options available for both manual and mechanized welding. This is essential for design and production planning when faced with the choice of competing processes such as MMA, MIG, TIG or plasma, helping engineers make the right choice for particular applications and ensuring the most cost effective welding techniques are employed. Five further chapters are devoted to the application of tube welding in the aero-engine, ship building, power generation, petrochemical and chemical plant industries with numerous details on processes, materials, techniques and equipment. The welding parameters and production data provided by the authors are a valuable source of information and will help engineers to overcome problems in production.This title includes Process options and manual techniques for welding pipework fabrications; Mechanised arc welding process options for pipework fabrications; Process techniques and equipment for mechanised TIG welding of tubes; Welding pipes for aero-engines; TIG welding pipework for ships; Automatic tube welding in boiler fabrication; TIG and MIG welding developments for fabrication of plant for the chemical, petrochemical, and offshore oil and gas industries; Fabrication of aluminium process pipework; A fabrication system for site mechanical construction; Qualification of welding procedures for the chemical process industry; Non-destructive examination of welds in small diameter pipes.

An investigation of aluminum pipe welding techniques for field construction is documented. Information from the Aluminum Association and the Aluminum Company of America (ALCOA) was evaluated to see whether their methods would be feasible for use by the Army Corps of Engineers. These procedures were then tested on aluminum piping commonly used in Corps construction (6061-T6 and 3003-H18). The investigation verified that these methods were viable for military applications. The information gained during this investigation was used as a basis for recommending guidance on aluminum welding which can be incorporated into Corps of Engineers and Army welding guidance. Among these recommendations are: (1) Use of appropriate cleaning procedures on the joint before welding; (2) Use of push-button to control the weld contactor; (3) Use of the gas tungsten-arc welding process; (4) Use of the extended land joint configuration; and (5) Use of current limits set by the Aluminum Association and ALCOA.
