Overview

Randomized trial evaluates mechanical properties of welds in metal components, highlighting spindle speed importance.

Key Points

  • This investigation aims to evaluate the mechanical properties of welds produced by rotary friction welding, focusing on spindle speed effects.
  • Fabricated welds using rotary friction welding on aluminium-aluminium, steel-aluminium, and steel-steel materials.
  • Conducted tensile tests, ultrasonic inspections, hardness tests, and metallographic analyses to assess weld quality.
  • Measured weld performance and micro structural characteristics at varying spindle speeds.
  • Optimal mechanical performance observed at 1,250 RPM, indicating the highest strength and hardness levels.
  • Loss of elastic resistance correlated with increased spindle speed due to micro-structural softening.
  • Ultrasonic testing confirmed all weld seams were free of defects, demonstrating quality at optimal conditions.
