Identifies different types of distortion of welded materials and describes techniques to be used to control and eliminate the distortion. This book of 15 chapters takes the mystery out of distortion control, and includes the following information: • The different modes of distortion and how welded fabrications are affected • Descriptions of various metal types and how the coefficient of expansion, thermal conductivity, yield strength, and modulus of elasticity affect distortion • Design strategies and shop practices which should be learnt as the first basic step to controlling shrinkage • Situations where appropriate restraining devices can make the difference between a quality product or a distorted weldment • Various methods for correcting distortion, including flame shrinkage • Procedure for bending and cambering beams using the power of weld shrinkage and flame straightening • Applications of rapid cooling procedures and heat build up preventatives • Tack welding skills combined with presetting techniques to overcome shrinkage problems when assembling weldments • Tips on using mechanical aids and procedures for teaching simple weldment assembly • Tools and devices, and how they are used to control distortion • Measuring and monitoring methods using a variety of techniques and instruments • Procedures for controlling distortion when welding and repairing light gauge sheet metal • Description of jigs and fixtures and their uses when welding both mild steel and nickel alloy sheet • Basic principles of pipe welding with practical examples of controlling distortion in problem areas • Information on preheating and different forms of post heat treatments • Techniques for preventing problems and controlling distortion during flame cutting •http://johnstewartbooks. weebly. com/
