Welding aircraft engine components can extend the life of the aircraft and keep it flying in the air. There are various types of welding processes and things that aviation welding technicians use to ensure the engine remains in perfect working condition. With the passing of time, technology has emerged, and as a result, technicians now have various opportunities to repair aircraft engines. There are multiple types of processes and welding techniques which are in play these days.

Let's take a look at the various ways in which welding technicians weld an aircraft's engine components.

Using arc welding

TIG welding is also known as Tungsten Inert Gas welding. It’s one of the most typical processes to manufacture and repair aircraft engine components. TIG welding includes using a type of procedure that has a pulse of high frequency. Also, keyhole plasma welding was a common type of welding that welding technicians used in the past.

There's now another type of welding called Metal Inert Gas (MIG) welding. This type of welding is under testing by industry experts. MIG welding is in the testing stage to use with a reduced spatter for the time being. We'll have to wait to see how the testing progresses and what comes out to be the final and tested variant of the process.

Using power beam welding

As time is progressing, advancements are becoming more and more frequent. The Ytterbium fiber lasers are one example that has made revolutionary changes in the landscape of aviation welding. It has introduced improvements in two significant elements of welding. The efficiency of the beam has seen enhancement to quite an extent. It has improved the quality of welding the components, which is very important when dealing with an aircraft's engine components. Secondly, the beamtime is now more and up to a limit that makes it easier to pull off the job with more precision, accuracy, and quality.

Electron beam deflection and other advancements in the probing techniques also play a vital role in increasing the welding processes.

Using linear friction welding

Linear friction welding (LFW) is another type of welding process aviation technicians use in the manufacture and repair of an aircraft's engine components. LFW is a very common, tested, and trusted technology. Most of the famous gas turbine aircraft engine manufacturers use this process. This process helps fabricate the bladed disks assemblies where blisks are another name you may use for bladed disks, as experts of the industry use it conventionally.

Using laser additive manufacture

People recognize this term also as LAM. You may call it a direct metal laser disposition (DMLD), direct metal disposition (DMD), or direct laser disposition. This process uses a laser to make a melt pool on the surface of the metal. While this process is going on, ceramic powder or metal powder is added through a nozzle to the melt pol. This process creates a 3D geometry.

There's yet another variation to this process that you can call selective laser melting (SLM). This process uses a bed of powder in which a focused beam fuses the powder placed priorly in a readymade form through scanning of the cross-section that the 3D CAD model of the surface of the powder bed creates.
