Welding and soldering (see solder) are techniques for joining metals metallurgically. Extractive metallurgy is the study and practice of separating metals from their ores and refining them to produce a pure metal. This article discusses the extraction of metals in general terms, but methods for ...
It is intended for undergraduate and graduate students of metallurgy, as well as those attending specialist welding courses.It is also a valuable source of reference for practising engineers and metallurgists concerned with joining processes. The text covers the metallurgical changes that take place ...
Joining Technologies for Powder Metallurgy Planetary CarriersPlanetary gear arrangements, in the simplest explanation, are comprised of a central, or "sun" gear, pinion or "planet" gears which drive or are driven by the sun gear, and an outer ring gear. Planetary carriers provide the housing ...
Planetary gear arrangements, in the simplest explanation, are comprised of a central, or "sun" gear, pinion or "planet" gears which drive or are driven by the sun gear, and an outer ring gear. Planetary carriers provide the housing for the planet gears, pinion pins, and associated bearings...
One of the most important production processes in metallurgy is fusion welding, the joining of two metallic objects in mutual contact by melting the surface regions and letting the weld metal resolidify. Many different methods of creating the molten zone have been developed, but they all have in...
Despite this obvious advantage of PM processes, joining materials synthesised from powders has been associated with difficulties related to their inherent characteristics, like porosity, contamination and inclusions, at levels which tend to influence the properties of a welded joint. This chapter presents...
JOHN C. LIPPOLD, PhD, is a professor in the Welding Engineering Program at The Ohio State University and leader of the Welding and Joining Metallurgy Group. A Fellow of both the American Welding Society and ASM International, Dr. Lippold has received numerous awards, including the Charles H. ...
Joining is the most important mechanical process necessary for PM parts to perform in actual service conditions expected in automobile parts and structural parts. Despite apparent advantages of PM processes, joining PM parts has been a tedious process, due to challenges associated with inherent ...
Cutting and grinding processes (turning, milling, shaping, planning, slotting, broaching, sawing, grinding). Joining processes (welding, bolting, riveting). A glossary of technical terms concludes this part of the book. 展开 年份: 1982
In addition, welding is commonly associated with resultant distortion, whereas PM parts are known to provide good dimensional and geometrical accuracy and thus, if machining operations are to be avoided, distortion must be minimised via selection of appropriate joining technology. Therefore, widespread ...
