- Chapter 5: Aircraft Welding › Shielded Metal Arc Welding (SMAW)
usually referred to as “stick” welding. The equipment consists of a metal wire rod coated with a welding flux that is clamped in an electrode holder that is connected by a heavy electrical cable to a low voltage and high ... prevent oxidation. The molten flux covers the weld and hardens to an airtight slag that protects the weld bead as it cools. Some aircraft manufacturers, such as Stinson, used this process for the welding of 4130 steel fuselage structures. This…

engine manufacturer specifies their use. Self-locking nut bases are made in several forms and materials for riveting and welding to aircraft structure or parts. [Figure 7-29] Certain applications require the installation of self-locking nuts in channels ... use in aircraft structures. Sheet spring nuts, such as speed nuts, are used with standard and sheet metal self-tapping screws in non-structural locations. They find various uses in supporting line clamps, conduit clamps, electrical equipment, access doors…
- Chapter 5: Aircraft Welding
With the right equipment and instruction, almost anyone with some basic mechanical skill, dexterity, and practice can learn to weld. There are three general types of welding: gas, electric arc, and electric resistance. Each type of welding has several variations ... addresses the welding equipment, methods, and various techniques used during the repair of aircraft and fabrication of component parts, including the processes of brazing and soldering of various metals. Types of Welding Gas Welding Gas welding is accomplished by heating…
