Is Welding All Aircrafts the Same?

Welding techniques and procedures vary depending upon the aircraft. Specifications of the aircraft determine what to do and how to do it.

Well, a question might pop up in your mind that aviation welders have to weld every aircraft in the same manner. One type of welding doesn't fit all the aircraft. This rule does not apply to the aviation welding industry. Every aircraft has some specifications that are not common to other aircraft types. Some of these specifications are under discussion in this article.

Difference in Metal

Aircraft manufacturers use different metals to manufacture various types and models of aircraft. As welding is all about the metal components, it varies with the type of metal. Iron parts will not be welded in the same way as they will weld an aluminum component.

Different metals have different characteristics as they behave differently upon heating during welding. Therefore, welding experts need to weld different metals in varying ways.

Different State of The Metal

Another thing is the metal's current state, which determines how the aviation welding professionals will execute their repairing procedures. Type of welding, heat, execution, and preprocess preparations are some of the things that depend on the condition of the metal.

Also, the primary decision of whether to weld or not to weld relies on the metal's state. If it is quite old, such as a vintage aircraft, there might be no use in welding it after a certain period.

Aircraft's Size

The size of the aircraft is proportional to the weight and pressure it puts on the metal components. Therefore, the welding technicians have to be concerned and attentive about applying the procedure. The welding joint must be able to withstand the weight and size of the aircraft.

Bigger aircraft do have not only more weight but also larger metal surfaces to deal with. The welding arc, the heat control, and other technical aspects vary depending on the aircraft's size.

Type of Engine

An aircraft's engine type determines at what speed an aircraft will fly. The speed enhances or reduces the pressure on the components such as the wings, propellers, and engine mount. The welding experts also need to look at the speed factor for ensuring they do the repair work accordingly.

Frequency of Flights

If there are two identical aircraft, one flies once in a month, and the other touches the sky every day, there is a huge difference. The welding process will require different strengths, approaches, and executing techniques for these two aircraft.

More flights mean more chances of wear and tear. Increased wear and tear call for a more durable and robust welding job to enable it to withstand. On the other hand, the aircraft that seldom goes midair will require extended repair work. Even when the repair work is necessary, it will not be an extensive one unless the aircraft meets an accident.

The Torque An Aircraft Has

Different aircraft have varying torques. Torque plays a significant role in the welding methods and requirements of the engine mount and engine components. When the aircraft starts, it takes a jerk due to its engine's torque when it is turning off. During the flight also, it affects the strength of the welding joints and repair work.

Capacity For Passengers

The number of passengers in an aircraft determines its weight during the flight. Weight is also a critical factor for the welding procedures and requirements of the technicians. Increased weight causes the components to weaken sooner as compared to an aircraft having lesser capacity. This is also a factor that varies the welding methods and execution techniques.

Professional experts know best which aircraft need welding to ensure its safety and prolonged life components. You must ensure your aircraft undergoes regular inspection and repair work by the best professional aviation welding technicians
