Why to measure residual stresses?

Manufacturing processes such as machining, welding, shot peening, heat treatment and grinding generate residual stresses. Residual stresses, depending on their sign, magnitude and distribution, can be either beneficial or detrimental. Residual stresses are indiscernible until the visual damage happens.

For the durability of the component it is essential to avoid the harmful effects of residual stresses and introduce the favorable ones. Residual stress measurement is applicable for product development and quality control.

Why to verify heat treatment results?

Heat treatment takes place somewhere in the middle of the component manufacturing process. Unsuccessful heat treatment defaces all the processes before and after heat treatment.

Success of heat treatment cannot be verified visually. With Stresstech solutions heat treatment defects like retained austenite can be detected non-destructively.

Why to detect grinding burn?

The surface of a freshly ground component may appear to be fine, but unseen damages below the surface, when gone undetected, can lead to serious problems for the end user. The grinding process has many parameters that effect grinding quality.

Undetected grinding burn may cause
  • internal quality failure on production line
    • extra costs: rework, scrap
  • external quality failure
    • warranty cases
    • brand value loss
