WebJan 27, 2015 · DEFINITION OF PEENING: Peening is a cold working process in which the surface of the component is deliberately deformed, in the basic method, by hammering. During peening, the surface layer attempts to expand laterally but is prevented from doing so by the elastic nature of the sub-surface, bulk material. This results in the development of ... WebMar 20, 2024 · Ultrasonic peening. The Ultrasonic Peening (UP) is a cold-working surface treatment process for fatigue life improvement of welded parts. It is called called utrasonic treatment or simply peening sometimes. The main objective of the ultrasonic peening is the release of the residual stresses generated by thermal effect of the welding process.
WebWelding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood. The completed welded joint may be referred to as a weldment. Some materials require the use of specific processes ...
