  In welding process, the deformation produced by weldment is called welding deformation. After welding, the residual deformation of weldment is called residual deformation of welding. The welding residual deformation with longitudinal contraction deformation, transverse shrinkage, angular distortion, bending deformation, distortion and wave distortion and a total of six species, of which longitudinal and transverse shrinkage deformation of weld shrinkage deformation is the basic form of deformation, welding in different, because the number of weld and position distribution of the two different. The deformation and deformation can be expressed as several other different forms.

  Under what conditions does the weldment produce a longitudinal shrinkage deformation? The shrinkage deformation in the direction of the weldment parallel to the length of the weld is called longitudinal shrinkage deformation. When the weld is located on the neutral axis of the weldment or several welds are distributed symmetrically at the neutral axis, the weldment will produce a longitudinal shrinkage deformation. The longitudinal shrinkage deformation of the weld increases with the length of the weld and the cross section area of the weld metal, and decreases with the increase of the cross sectional area of the weldment.
