FLUX-CORED ARC WELDING : Advanced (Book with DVD) (Workbook Included)

Flux-Cored Arc Welding: Advanced comprehends various diverse practical and visual skills with knowledge of specialized materials and techniques. Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant-voltage or, less commonly, a constant-current welding power supply. An externally supplied shielding gas is sometimes used, but often the flux itself is relied upon to generate the necessary protection from the atmosphere, producing both gaseous protection and liquid slag protecting the weld. The process is widely used in construction because of its high welding speed and portability. This book will introduce the knowledge and skills for those studying and/or working in welding industry to interpret and convey information in response to workplace requirements.

About this Book

This book covers the information consists of basic to core competencies that a person must achieve to weld alloy steel plates and pipes components as specified by layout, blueprints, diagrams, work order, welding procedure or oral instructions using FCAW welding equipment.

About the Flux-Cored Arc Welding Industry

Flux-Cored Arc Welding (FCAW) utilizes a continuously-fed tubular electrode, electrical power to melt the electrode, and may or may not use shielding gas from an externally supplied source when depositing material in the weld joint. The flux-cored electrode is a composite tubular filler metal consisting of a metal sheath with a core of mineral compounds and powdered metals. The resulting weld bead is covered by a residual slag (melted and solidified flux) which helps to protect and shape the finished weld, and is generally easily removed upon completion of the weld. Flux Cored Welding combines the high productivity of MIG welding using a solid electrode with the ability to weld on more contaminated base material. When compared with MIG welding, higher deposition rates are possible, especially when welding out of position. Welders fabricate and assemble metal structures and equipment through the use of welders, cutters, shapers and measuring tools. Welders set up, operate and maintain welding equipment. They understand and implement personal and company safety measures by wearing specialized goggles, helmets and gloves. Communication skills are essential to work with team members and converse with customers and clients. A job as a Welder falls under the broader career category of Welders, Cutters, and Welder Fitters. Welders operate and maintain the machines that fabricate and repair metal structures, equipment and machinery. Welders are qualified for positions in a variety of fields based on their skill level and experience, including shipbuilding, automotive, construction and manufacturing industries. Opportunities are expected to be better for skilled welders trained in the latest technologies due to the difficulty employers are facing finding qualified workers.
