Why are airplanes riveted and not welded

Why are airplanes riveted and not welded? In this video, we will reivewe science, metallurgy, and engineering behind aircraft joining methods. We compare riveting vs welding, examine heat-treatable aluminum alloys (2024, 6061, 7075), discuss heat-affected zones in aluminum welding, and explore why fusion welding is rarely used on commercial airliners. You’ll learn how airplanes meet critical performance requirements such as high specific strength, lightweight structure, corrosion resistance, fatigue resistance, vibration tolerance, uniform material properties, and distortion-free assembly. The video explains how conventional welding changes aluminum properties, reduces strength, and creates unpredictable deformation—making riveting the preferred method for fuselage, wings, frames, and skin panels.
