In metallurgy, peening is the process of working a metal's surface to improve its material properties, usually by mechanical means, such as hammer blows, by blasting with shot (shot peening), focusing light (laser peening), or in recent years, with water column impacts (water jet peening) and cavitation jets (cavitation peening).

Sep 20, 2019 · The term “peening” refers to any metalworking process that’s intended to improve the physical properties of metal. When executed correctly, it can make raw metal stronger and less ductile. Most forms of peening are mechanical, such as hammer peening.

Aug 7, 2023 · In this article, we’ll explore the fascinating world of shot peening, a process that enhances metal surfaces through high-speed projectile blasting. Get ready to discover how this innovative technique works its magic, from boosting fatigue resistance to improving wear and corrosion resistance.

Jan 11, 2024 · Shot peening is a cold working process that alters the mechanical properties on the metal’s surface and creates a compressive residual stress layer. Its primary purpose is to prevent the spread of microcracks on a surface.

Mar 23, 2023 · Peening involves striking a metal surface with a specialized peening hammer or other hard object to create a compressive stress layer. This process is commonly used in welding to improve the strength and durability of the weld joint.

Dec 20, 2019 · Peening is an effective method used to balance the shrinkage of a weld puddle as it cools down. Generally, peening the weld bead thins it out by stretching it over the surface. This helps reduce the stresses induced by the contraction of the metal as it gets cooler. Peening is considered a cold working process.

Jan 19, 2025 · Shot peening is a cold working process used to enhance the mechanical properties of metal components by preventing fatigue and stress corrosion failures. It involves bombarding the metal surface with small spherical particles, or shot, made of materials like steel or ceramics.

Jul 19, 2024 · Peening is a surface modification process used to improve a material by the application of a mechanical force. It is used to strengthen a metal surface, thereby making it more resistant to external degradation and corrosion factors. There are two main types of peening: hammering and blasting.

Apr 12, 2024 · At its core, shot peening is a cold working process that utilizes the impact of spherical media, typically steel, ceramic, or glass beads, to create a layer of compressive stress on the surface of a material.

Jul 30, 2023 · Shot peening is a forming technique that uses high-speed shot flow to strike the surface of a metal sheet, causing plastic deformation in the impacted surface and the underlying metal material, thereby gradually causing the sheet to bend towards the peened surface, achieving the desired shape.
