GMAW/FCAW Libri GmbH GMAW/FCAW Welding Techniques

Running a bead is easy. Producing a strong, consistent, code-conscious weld-and knowing exactly what to change when something goes wrong-requires a deeper understanding of the process.GMAW/FCAW Welding Techniques bridges the gap between welding theory and practical shop-floor judgment. Instead of giving you settings to memorize, it explains why the arc, wire, gas, equipment, and technique behave the way they do, helping you diagnose problems and adapt confidently when conditions change.
Inside, you'll learn how to: - Understand GMAW and FCAW from the arc outward, including short-circuit, globular, spray, and pulsed spray metal transfer.- Set up equipment correctly, from power sources and wire feeders to drive rolls, contact tips, liners, guns, and work connections.- Select shielding gases and electrodes for carbon steel, stainless steel, aluminum, indoor fabrication, and field work.- Choose voltage, wire feed speed, stickout, and travel speed for thin material, heavy sections, and out-of-position welding.- Improve gun manipulation and bead control across flat, horizontal, vertical, and overhead positions.- Diagnose common weld defects, including porosity, incomplete fusion, undercut, spatter, burn-through, cracking, slag inclusions, and distortion.- Understand welding symbols, WPS requirements, inspection methods, AWS/ASME code concepts, and welder qualification.- Use quick-reference appendices covering welding parameters, wire classifications, welding symbols, positions, and troubleshooting.Written for apprentices, working welders, instructors, fabricators, and serious hobbyists, this guide is designed to make every hour under the hood more productive.Build better welding judgment, troubleshoot with confidence, and take your GMAW/FCAW skills beyond trial and error-get your copy today.
