This book is entitled to laser welding processes. The objective is to introduce relatively established methodologies and techniques which have been studied, developed and applied either in industries or researches. State-of-the art developments aimed at improving or next generation technologies will be presented covering topics such as monitoring, modelling, control, and industrial application.
Discovered almost fifty years ago at Bell Labs (1964), the Nd:YAG laser has undergone
an enormous evolution in the years, being now widely used in both basic research and
technological applications. Nd:YAG laser is extremely versatile in its output
characteristics, yielding emission from continuous wave to very large energy pulses or
very high peak-power pulses. Also, it covers a large spectral range, namely near
infrared, visible (second harmonic) and ultraviolet (third to fifth harmonic).
Despite the wide availability of literature on welding processes, a need exists to regularly update the engineering community on advancements in joining techniques of similar and dissimilar materials, in their numerical modeling, as well as in their sensing and control.
In both the United Kingdom and the United States of America,
there is a legislative framework that assigns a very large measure
of responsibility to employers for the health and safety of their
employees. The detailed approach is slightly different and readers
need to familiarise themselves with the requirements. Where they
have doubts, they should consult the enforcing authorities for
• The Health and Safety Executive (United Kingdom)

Assembly is a very important part of most product realization processes.
Aluminum is the second most plentiful element on the earth and it became a
competition in 19th century. The huge demand of aluminum is projected to get 70
million tons, over 30 millions being obtained from recycled scrap. The scope of
aluminum ranges from household to space vehicles.
