4. Thermomechanical treatment of welded assemblies
SCROLL TO TOP
4.1.1 Principle
Using a mechanism identical to that created by welding,
hot shrinkage straightening is a simple, effective method that involves
very localized heating, either in the skin (thick parts) or in the
thickness (thin parts), which generates, through thermal expansion
plasticity, a contraction of the plasticized zone as it cools. The
resulting deformation components are :
