Metallurgy and Mechanics of Welding: Processes and Industrial Applications

---

What a long story welding is! Seeing the light of day at the end of the 19th
century in the mind of scientists, it passed quickly into the hands of technicians, first
of all with the oxyacetylene technique, then with arc welding and resistance welding
techniques. Other processes (we will not quote them all in this introduction) then
followed and the 20th century ended with laser welding which had its origins in the
1980s.

However, it must be said that only since the 1950s has welding been the main
means of assembly, as riveting was the most used method up to that point.
In fact, after abandoning this method to some extent, scientists renewed their
involvement in the 1930s. In France, at the time, Albert Portevin set out Les bases
scientifiques de la soudure autogène and a higher education teaching programme
began in 1931 at L’Institut de soudure. In the 1930s welding was implicated in
bridge failures, notably in Germany and Belgium, then during World War II came
the failure of Liberty ships constructed in great numbers thanks to the technique of
welding. Other later catastrophic failures affected pressure vessels. It is in this
context that in 1948 L’Institut international de la soudure (IIS/IIW) was founded. It
met the need for international collaboration, in particular with regard to safety and
research, expressed by different national bodies and by the whole welding world,
from scientists to users. Today in 2008, the IIS/IIW holds its 61st annual meeting: 16
commissions, with sub-commissions and study groups, cover the whole field of
welding, from design to performance and safety, including teaching and research.
This demonstrates the importance of this collaboration and the richness of its
contribution.

Welding can be regarded, like the language of Aesop, as the best and worst of
things. Indeed, it makes it possible to bond almost all materials, from metals to
plastics, with continuity; however, this does not imply homogenity. The processes
and hence possibilities are very numerous depending on the types of assemblies to
be made, the properties required and evident economic constraints to be respected.
At the same time welding can be regarded as the weak link of the majority of
constructions as it is often called into question when problems arise. In the examples
cited above (bridges, Liberty ships, pressure vessels) it is the welding that is called
into question each time – often it must be added linked to a parent metal whose
resistance to a sudden failure is insufficient.
