Distortion Control is a welder's responsibility
Note the half ring type yokes welded to turbine blades to minimize distortion during the welding operation
Without proper preparation a project of this magnitude would be scrapped.
A welder who is familiar with all of the distortion control procedures is a key man in any shop.
Distortion Control
LEARN PROVEN TECHNIQUES To control distortion before it happens
Distortion Control is Everyone's Responsibility: every once in a while, though, something goes awry on the shop floor that results in twisted and warped work, and requires extra labor and unnecessary expenses to correct, if correction is at all possible.
Quite often the job may have to be scrapped. Most of the time, no one really knows who is to blame, although the finger is easily, and sometimes unfairly, pointed at the welder or his boss.
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 learned 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
