Longitudinal shrinkage in welding
Webdistortion, the transverse shrinkage and the longitudinal shrinkage. The levels of the welding distortion depend mostly the heat input and the thickness of the plate and they can be determined either by experiment or by thermal-elastic-plastic analyses. It is relatively easy to predict the welding distortion in a simple specimen in a laboratory. WebWelding distortion can be classified into six types (modes) as illustrated in Fig. 1.Three of them are in plane, namely, transverse shrinkage, rotational distortion, and longitudinal shrinkage, and three are out of plane, namely, angular distortion, longitudinal bending (also known as bowing or camber distortion), and buckling distortion.

This type of crack is delayed in forming and may take up to 72 hours to appear. It generally occurs because of hydrogen embrittlement or residual stresses that exceed the strength of the filler metal or base materials.

WebLongitudinal shrinkage is one of dimentional change in parallel of butt weld joint and bead weld. It is important in welding of sheet metal , because it is the mean factor to buckling along the weld line . Researchers dimentional changes as longitudinal shrinkage have studies by analytical, numerical and finite element methods. http://mgok.muszyna.pl/mfiles/aartjes.php?q=weld-shrinkage-b8d4c
