'Residual stresses' presentation slideshows

The 4 of the common types of NDT used when assessing weldments are:

Non Destructive Testing. We use Non Destructive Testing ( NDT ) when we wish to assess the integrity of a structure without destroying it. The 4 of the common types of NDT used when assessing weldments are:. Penetrant Testing. Magnetic Particle Testing. Ultrasonic Testing.

Stress Relieving

Stress Relieving. What are Residual stresses :. Developed in the weldment mainly due to the restraint provided to the shrinkage strains. In thin materials, the shrinkage strains are accommodated by distortion of the plates.

Rolling mill

Rolling mill. Introduction to Rolling. Rolling is a bulk deformation process in which the thickness of the work is reduced by compressive forces exerted by two opposing rolls. The rolls rotate to pull and simultaneously squeeze the work between them. Introduction to Rolling.
