Description
  • Welding in the aerospace industry has seen some
    very fascinating and exciting developments in
    recent years. The ever improving knowledge of
    welding material, designs and welding as a whole
    are paving the way for welding being implemented
    in aeronautics.
  • Welds have been replacing rivets and bolts since
    World War 2 and hence, has become a favourite for
    the military, ship building and the aeronautics
    industry. This is for the simple reason that
    welding is cost-effective as compared to rivets,
    welds require less year-on-year maintenance,
    welding is structurally sound while being
    light-weight and rivets simply just add on to the
    weight of the aircraft or of the project.
  • Preferred types of welding in this industry are
    diffusion welding, laser welding and
    electron-beam welding. There are a few other very
    promising welding methods which are slowly
    gaining popularity and establishing quick effects
    too. These are, friction stir welding and
    variable polarity plasma welding.
  • While welding in aerospace is making
    ground-breaking improvements, there are certain
    challenges that are posed in the aerospace
    defense industry. Lets have a look at those

  • Uncommon Materials
  • Materials used in welding for the aerospace and
    defense industry are often different from the
    common usage. Why? They need more malleable,
    ductile yet at the same time sturdy and
    lightweight metals.
  • Thus, exotic metals and materials are used in
    aerospace applications. These are materials like
    stainless steel, and aluminium to begin with and
    high-end materials like inconel and titanium are
    widespread.
  • Complex Joint Designs
  • With unique and new structures in this industry,
    there are many complex joints and designs that
    have to be aced. Welding is the right choice for
    it, because rivets cannot do a job as smooth and
    seamless and very importantly, as lightweight as
    welding can. This requires efficient processes in
    the assembly line as well as the best of the best
    methods of welding.
  • For the purposes of overcoming the challenge of
    joints and uncommon designs of megastructures,
    electron-beam welding and laser welding are the
    best choices to weld two complicated parts and
    metals.

  • Airtight Sealing
  • In case of both aerospace as well as military
    counterparts of it, airtight sealing is required
    to protect sensitive material, both electronic
    and otherwise. Expensive gear that has to be
    uncompromised at all points, without any other
    failures and at all costs need this hermetic
    approach to be followed through.
  • This would not be possible without welding, and
    thus welding is not just a great choice, but also
    a must.
  • High thermal conductivity
  • Most metals, alloys and materials used in these
    industries have a very high thermal conductivity.
    Along with this, these materials also have a high
    crack sensitivity which makes it challenging for
    the welder.
  • The materials are difficult to weld with the
    common methods of welding since high standards of
    quality, airtight sealing and more is required of
    them. Therefore, more advanced ways of welding
    like electron-beam welding and laser welding are
    the preferred methods.
  • These are a few among the many challenges that
    one faces in the aerospace industry while
    welding. But its a vast universe in itself, and
    a very interesting one at that!
