This process consists in heating with a flame very quickly punctually or over a narrow area a sheet or a welded set of pieces. This operation allows to rectify the distortions on the thermally affected zone during the welding cycle.

This shrinking process, particularly used in the shipyards, can be performed with carbon sttels and stainless steels. Gases used for the heating flame are oxygen and acetylen.
