Key Terms
Almen Strip
Shot peening technicians expertly use Almen strips to measure the intensity and coverage of shot peening processes, ensuring optimal surface treatment for enhanced metal fatigue resistance. They carefully place Almen strips on parts, analyze arc heights after shot peening, and adjust parameters to maintain consistent shot intensity. Proficiency in interpreting Almen strip readings is critical for verifying process control and meeting industry standards in aerospace, automotive, and manufacturing sectors.
Coverage
Shot peening technicians specialize in applying controlled mechanical impacts to metal surfaces, enhancing fatigue strength and resistance to stress corrosion. Their coverage includes inspecting and preparing components, operating automated peening equipment, and ensuring adherence to industry standards such as SAE J442 and AMS 2432. Proficiency in interpreting technical specifications and verifying uniform surface coverage is critical for optimizing the durability of aerospace, automotive, and industrial parts.
Intensity
Shot peening technicians measure and control the intensity of shot peening to enhance metal fatigue strength. Intensity is a critical parameter determined using Almen strips, ensuring consistent coverage and compressive stress on the workpiece. Precise control of intensity prevents surface damage and improves the durability of automotive, aerospace, and industrial components.
Media Type
Shot peening technicians specialize in operating and maintaining equipment that uses media such as steel, ceramic, or glass beads to improve metal fatigue resistance and surface durability. Proficiency in selecting the appropriate media type is crucial for optimizing shot peening processes across various materials and applications. Mastery of media characteristics directly impacts the quality and longevity of treated components in aerospace, automotive, and manufacturing industries.
Nozzle Angle
Shot peening technicians must precisely control the nozzle angle to ensure optimal surface coverage and stress distribution on metal parts. Maintaining the correct angle, typically between 70 and 90 degrees, maximizes the compressive residual stress needed to improve fatigue strength. Incorrect nozzle angles can lead to uneven peening intensity, compromising the integrity and lifespan of aerospace, automotive, and industrial components.
