The present invention relates to the field of residual stress machining deformation control technology, and in particular to a method for controlling workpiece deformation during machining. Background: Machining deformation is primarily caused by four factors: the initial residual stresses in the blank, clamping forces, cutting forces, and cutting heat, as well as residual stresses induced by the machining process.

This book focuses on how to control welding deformation. The contents include the law of welding deformation and the calculation of welding bending deformation of beams and columns, the calculation of pre-arching of the web plate of box girders of welded plate structures, the method of reducing welding deformation

Post-weld stress relief treatment: 1, the overall heat treatment: the degree of stress relief is mainly determined by the composition of the material, organisation, heating temperature and holding time. Low carbon steel and some low alloy steel welding components at 650 degrees, insulation 20 ~ 40h, can basically eliminate all residual stresses
