3.1 Hammering during welding
3.1.1 Principle and role of hammering during welding
This treatment, which is preferably applied to thick, full-thickness chamfered parts in C-Mn and austenitic Cr-Ni stainless steels, consists in subjecting each pass to surface hammering to generate localized plastic deformation that produces the following two effects:
compensation of the various welding deformation components to ensure precise geometric tolerances;
