Welding is a complex process, is increasingly automated, and operates at higher speeds in more difficult environments. Defects also need to be detected as they arise to ensure efficient, high-quality production. All these needs have led to a growing interest in the use of sensors to provide accurate, robust, realtime monitoring where this cannot be achieved by more traditional testing and inspection techniques. This important book reviews the range of monitoring techniques available and their applications.

Spite the critically important role welding plays in nearly every type of human endeavor, most books on this process either focus on basic technical issues and leave the science out, or vice versa. In Principles of Welding, industry expert and prolific technical speaker Robert W. Messler, Jr. takes an integrated approach--presenting a comprehensive, self-contained treatment of the welding process along with the underlying physics, chemistry, and metallurgy of weld formation.
Promising to become the standard text and reference in the field, this book provides an unprecedented broad coverage of the underlying physics and the mechanics of solidification--including peritectic and eutectic reactions--and emphasizes material continuity and bonding as a way to create a joint between materials of the same general class. The author supplements the book with hundreds of tables and illustrations, and correlates the science to welding practices in the real world.
Principles of Welding departs from existing books with its clear, unambiguous presentation, which is easily grasped even by undergraduate students, yet given at the advanced level required by experienced engineers.

Engineering Plasticity and Impact
Publisher: World Scientific
Pages: 340
2002-04-15
ISBN 9810248032
PDF 15 MB
Plasticity and impact dynamics are two important areas in engineering practice, which includes structural engineering, crashworthiness, metal formation and new structural materials. The application of engineering plasticity and impact dynamics has resulted in significant achievements both technically and economically. This book presents the state-of-the-art developments in the above fields. It contains over 15 chapters written by experts in engineering plasticity and impact dynamics. It covers a wide range of theoretical developments and engineering applications, including fundamentals of energy absorption, applications of new materials, crashworthiness, bifurcation in plasticity, microdynamics, penetration, wave propagation, fracture, laser impact and particle-impact-induced erosion.

Highways Department (HyD) of Hong Kong SAR is turning their idea for a world class bridge across
Rambler Channel at the entrance to Kwai Chung Container Port into reality. Due to the spectacular
location, HyD selected the concept for the bridge through an international design competition. The
competition took place in the first half of 2000 and the winning concept was a cable-stayed structure
with freestanding towers located between twin box girder decks. The 1018m main span is in steel,
while the four back spans each side are in concrete. The two towers stand on shore, providing
unobstructed access to the busy container port with a minimum navigation headroom of 73.5m.
A number of modifications were introduced to the scheme during subsequent technical review.
Detailed design started in March 2002. Tender was called in August 2003 and returned in December
2003. The construction contract was awarded to the Maeda-Hitachi-Yokogawa-Hsin Chong Joint
Venture, and construction began in April 2004. At the end of 2007, the concrete back spans were
complete and the towers were well on their way to their final heights of 298m forming significant
landmarks against the backdrop of Hong Kong harbour. Major sections of the steel deck, fabricated in
China, are now on site, with the areas around each tower erected by a 4000T heavy lift strand jacking
scheme. The first of the prefabricated parallel wire stay cables have been erected. Completion of the
bridge is scheduled for 2009.
