Best Metallurgy Engineering

Explains each type of welding, including stick, tig, mig, and fluxcore welding, as well as oxyfuel cutting, which receives sparse coverage in other books on welding Tips on the best welding technique to choose for a specific project Required training and certification information. This friendly, step-by-step guide helps you master this commonly used yet complex task, taking you from material evaluation all the way through the welding process. You'll apply finishing techniques, adhere to safety practices, and learn other methods like brazing and soldering. Keep yourself safe — find the right protective gear, manage your workspace, and take care of your equipment. Create cool projects — get started with a basic torch cart and then take it up a notch with a portable welding table and a campfire grill.

Finalist for the Los Angeles Times Book Prize ** A Wall Street Journal Best Book of the Year Rust has been called “the great destroyer,” the “pervasive menace,” and “the evil.” “This look at corrosion—its causes, its consequences, and especially the people devoted to combating it—is wide-ranging and consistently engrossing” ( The New York Times ). This entropic menace destroys cars, fells bridges, sinks ships, sparks house fires, and nearly brought down the Statue of Liberty’s torch. “Jonathan Waldman’s first book, Rust , sounds like a building code violation. At one point, a canning executive hostile to Mr. Waldman’s questions tells him rust is ‘a silly subject to write about.’ It is a testament to Mr. Waldman’s skill and perseverance that this book proves that man so thoroughly wrong.” —Gregory Cowles, The New York Times “Compelling . Mr. Waldman does a masterful job of interweaving elements of the science and technology.” —Henry Petroski, The Wall Street Journal. “It never sleeps, as Neil Young noted: Rust is too busy wrecking our world. The relentless, destructive process has downed planes, sunk ships, crashed cars, dissolved priceless artifacts, and committed countless other crimes of corrosion. The clarity and quiet wit of Waldman’s prose, his gift for narrative, his zeal for reporting and his eye for detail, these things and more put him in a class with John McPhee and Susan Orlean.” —Mary Roach, author of Stiff , Bonk , and Gulp. “In this remarkable book, Jonathan Waldman takes one of our planet’s oldest, most everyday—and most dangerously corrosive—chemical reactions and uses it as the starting point for a literary odyssey. A silent rebuke to the hype of the modern, it never stops its good work of blunting the cutting edge. Jonathan Waldman weaves together cultural history with a history of the stuff on which culture is built, showing how the drama of human striving and renewal are inescapably tied to limit and decay." “Waldman is a bright and curious companion in this lively adventure in search of the scourge of rust and its ingenious opponents.” —Kirkus Reviews. A detailed, fun read with a valuable reminder that every seemingly irrelevant item we take for granted each day is front and center for someone else.” —Publishers Weekly. A Ted Scripps Fellow in environmental journalism at the University of Colorado, Jonathan Waldman grew up in Washington, DC, studied environmental science and writing at Dartmouth, and earned a master’s degree from Boston University’s Knight Center for Science Journalism in 2003. He has spent the last decade writing creatively about science, culture, and politics for Outside , The Washington Post , McSweeney’s , and others.

Miodownik studies objects as ordinary as an envelope and as unexpected as concrete cloth, uncovering the fascinating secrets that hold together our physical world. " Stuff Matters is about hidden wonders, the astonishing properties of materials we think boring, banal, and unworthy of attention...It's possible this science and these stories have been told elsewhere, but like the best chocolatiers, Miodownik gets the blend right." University professor Miodownik accomplishes a bit of a miracle here by making a discussion of materials science not only accessible but witty as well.

A Perfect Red recounts the colorful history of cochineal, a legendary red dye that was once one of the world's most precious commodities. "Elusive, expensive and invested with powerful symbolism, red cloth became the prize possession of the wealthy and well-born," Greenfield writes in her intricate, fully researched and stylishly written history of Europe's centuries-long clamor for cochineal, a dye capable of producing the "brightest, strongest red the Old World had ever seen." Striving to maintain a trade monopoly, Spain fiercely guarded the secrets of cochineal cultivation in Mexico and only after centuries of speculation (was the red powder derived from plant or animal?). Greenfield recounts the wild, clandestine attempts by adventurer naturalists to cultivate both the cochineal insect and its host plant, nopal, beyond their native Mexico, acts of folly driven by the desire for scientific fame and commercial profit. Native to Mexico, the scale insect cochineal was first harvested as a dyestuff by the ancient Aztecs, and once its properties were discovered by European conquistadors, it became the quarry in an international race to obtain a monopoly on its production.
