Welding Deformation and Residual Stress Prevention

Welding Deformation and Residual Stress Prevention

Engineers and designers know that Welding causes deformation (shrinkage, cracks, and distortion) in materials. These deformations will ultimately lead to major failures in structures including bridges, rockets, ships, pipelines and pressure vessels. Therefore, the prediction and reduction of welding deformation is of critical importance.

Although the problem is well researched, there are very few tools to meet the demand. Welding Deformation and Residual Stress Prevention provides a unique computational approach to the prediction of the effects of deformation and residual stress on materials. The book provides:

  1. the basic theories and analysis procedures are described using a simple three-bar model.
  2. One pack of software is provided to perform basic analysis.
  3. Examples of strategic methods and procedures are illustrated to have solved various welding-related problems encountered in the process of construction.
  4. Supplements present data bases for welding residual stresses, temperature dependent material properties.

The goal is to provide engineers and designers with the ability to create their own computational system for predicting and possibly avoiding the problem altogether.
