The Practical Reference Guide for Welding Titanium

1999-01-01
Titanium need not be all that hard to weld! In industrial sectors the common opinion is that titanium alloys are difficult to weld. While it is true that titanium alloys can be embrittled by carless welding techniques, it is equally true that these materials are much more weldable than their reputation suggests. This reference guide discusses the difficulties that originate from several basic sources when welding titanium and titanium alloys. The high reactivity of titanium with other materials, poor cleaning of parts before joining, and inadequate protection during welding can lead to contamination, porosity and embrittlement of the completed joints. Topics Covered: • Weld Cleaning • Gas Shield Arc Welding Processes • Gas Tungsten Arc Welding • Gas Metal Arc Welding • Plasma Arc Welding • Other Welding Processes

Hyperspectral Remote Sensing

2012-01-01
Hyperspectral remote sensing is an emerging, multidisciplinary field with diverse applications that builds on the principles of material spectroscopy, radiative transfer, imaging spectrometry, and hyperspectral data processing. While there are many resources that suitably cover these areas individually and focus on specific aspects of the hyperspectral remote sensing field, Hyperspectral Remote Sensing provides a holistic treatment that captures its multidisciplinary nature. The content is oriented toward the physical principles of hyperspectral remote sensing as opposed to applications of hyperspectral technology. Readers can expect to finish the book armed with the required knowledge to understand the immense literature available in this technology area and apply their knowledge to the understanding of material spectral properties, the design of hyperspectral systems, the analysis of hyperspectral imagery, and the application of the technology to specific problems.
