Operations such as rough machining and cold forming can generate residual stresses in parts. If not removed, these stresses can release themselves in an uncontrolled fashion causing dimensional issues. In stress relieving, parts are taken to and held at an appropriate temperature to relieve the residual stresses created in the prior operations.
Operations such as rough machining and cold forming can generate residual stresses in parts. If not removed, these stresses can release themselves in an uncontrolled fashion causing dimensional issues at subsequent operations. This process is required on welded material to keep them stress-free.
