# Chapter 5 Aircraft Welding 

## Introduction 

Welding can be traced back to the Bronze Age, but it was not until the 19$^{th}$ century that welding as we know it today was invented. Some of the first successful commercially manufactured aircraft were constructed from welded steel tube frames. 

As the technology and manufacturing processes evolved in the aircraft and aerospace industry, lighter metals, such as aluminum, magnesium, and titanium, were used in their construction. New processes and methods of welding these metals were developed. This chapter provides some of the basic information needed to understand and initiate the various welding methods and processes.
