A Clean Solution for Shot Peened AluminumShot peening is often referred to as the bombardment of metals with shot, or very small aluminum balls, in order to increase its material properties such as yield stress and porosity. This process can also increase the cycle life on a component, as it is less likely to crack or fracture. Shot peening is very similar to shot blasting, however, shot peening tends to be less abrasive and removes less material from the parent metal, resulting in a smaller amount of dust generation.
Without proper ventilation, shot peening booths can experience a problematic accumulation of aluminum debris on the floor and other surfaces, as well as aluminum dust and shot particles dispersing through the air. These particulates have a high potential for causing fires and explosions, requiring properly engineered equipment and systems to be used to minimize risk. An explosive event could shut down a company’s entire process so that extensive inspections and repairs can be made.
An industrial fabricator of welded aluminum components required for the construction of bridge assemblies utilized a shot peening process to finish their parts. Used extensively in the aerospace industry, shot peening is an effective method of surface finishing that will strengthen and provide stress relief to metal and alloy parts while also helping to prevent the propagation of micro-cracks.
