When a welding process is done on a metal component of an aircraft exhaust system or engine mount, it undergoes two main types of changes. The metal expands when it’s heated and on cooling down it contracts. These changes in the form of the metal affect the aviation welding quality. An expert aviation welding technician must factor this in while applying welding on the metal so that it remains in perfect shape after the cooling process.

Unevenness is a problem

When metal expands in an uneven manner, it also compresses in an irregular pattern. It results in warping and buckling of the metal pipes and other components. It is of pivotal nature that the welding process is carried out while keeping in mind the changes that will happen on heating and cooling. It will enable the welder to adjust the welding temperature, precision, and accuracy so that after cooling down the pipe results in the desired shape and form.

Leaving the margin

It’s very important to leave the margin of contraction and expansion while performing the welding process. It requires expertise, practical knowledge in the field, and mastery, to predict and assess what and how much will the change be in the metal so that he can do his job accordingly.

The touch and finesse of a master welder will minimize or completely eradicate the chances of warping and buckling of metal after a welding process. The uneven shape of metal pipes in an aircraft exhaust system or in the engine mount can cause problems to the fitting, performance, and safety of the aircraft.

How much margin should be given to the metal while welding it depends on several factors, such as the thickness and type of metal sheet being used. This is what an expert aviation welding technician knows well. They know how to deal with different types of metal sheets and components when welding them, keeping in mind the changes it would undergo during and after the welding process.

It’s not about the looks

It’s not just a matter of appearance. The uneven and irregular surface may cause serious cracks, leakage, and other problems to the exhaust pipes. It can further cause serious damage to the aircraft.

If we talk about the aircraft engine mounts, it’s all about the precision and accuracy of the pipes. A minor change in the form of the mount can make it unfit. The slightest of bends can cause complete replacement of the engine mount. It will not only take lots of time but it’s also costly. Even if a deformed engine mount or even an exhaust system is installed somehow, it can cause catastrophic consequences. It’s crucial not to make any compromises when the welding job has not gone exactly how you planned it. If there is any slightest of changes in the form, shape, or condition of the metal, adequate measures must be taken.

The plane should only be cleared for flight if the welding job has been done perfectly and the installation is done without any mistakes and imperfections.
