SUBMERGED ARC WELDING : Intermediate (Book with DVD) (Workbook Included)

Submerged Arc Welding: Intermediate comprehends various diverse practical and visual skills with knowledge of specialized materials and techniques. Submerged-arc welding (SAW) involves the formation of an arc between a continuously fed electrode and the work piece. A blanket of powdered flux, which generates a protective gas shield and a slag (and may also be used to add alloying elements to the weld pool), protects the weld zone. A shielding gas is not required. The arc is submerged beneath the flux blanket and is not normally visible during welding. This process can be performed both indoors and outdoors, wherever it is most convenient to place the equipment. 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 competencies that a person must achieve to weld pipe components as specified by layout, blueprints, diagrams, work order, welding procedure or oral instructions using SAW welding equipment.
About the Submerged Arc Welding Industry
Submerged arc welding, often abbreviated SAW, is a specific and popular type of arc welding where the area being melted and welded is covered by a blanket of flux. This provides welders with several advantages, from reducing UV radiation to providing a higher quality weld. Traditional arc welding uses an electric current to create an arc of electricity between an electrode and the metal being worked on. This electrical arc melts and joins the materials together, and the electricity can be provided by either a direct current (DC) or alternating current (AC). The difference between traditional arc welding and submerged arc welding is the layer of flux that covers the materials. Flux is a material that, when melted, creates a pathway for the electrical arc to travel through. The arc travels from the electrode, through the flux, and to the material that needs to be welded. This method can also use either a direct or an alternating current. 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
