GAS WELDING : Intermediate (Book with DVD) (Workbook Included)

Gas Welding: Intermediate comprehends various diverse practical and visual skills with knowledge of specialized materials and techniques. Gas welding Metal joining process in which the ends of pieces to be joined are heated at their interface by producing coalescence with one or more gas flames (such as oxygen and acetylene), with or without the use of a filler metal. 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

The information in this book consists of competencies that a person must achieve to perform gas welding in alloy steel plates and tubes components as specified by layout, blueprints, diagrams, work order, welding procedure or oral instructions using Gas Welding equipment.

About the Gas Welding Industry

Gas welding, also called oxy-fuel welding, is a system of welding that uses one of various gases and oxygen to ignite a torch. Welding is defined as the process of combining two materials, usually metal, by heating them until both ends become molten. Filler materials are generally added into this molten material, and the two ends are joined together and allowed to cool, forming one solid piece. Common gases used in gas welding include natural gas, propane, hydrogen, liquefied petroleum, propylene, and acetylene, with acetylene being the most common. In many cases, one gas is not beneficial over another, although in some situations a specific gas may be preferable. For example, one gas may heat higher or lower than another, making it more convenient to use with certain metals. A variety of metals can be joined using gas welding techniques, although a skilled torch operator is necessary in order to ensure a smooth weld. Not all metals melt at the same temperature, so the welder must know how long to heat varying types of materials. There is also a certain level of skill required for gas welding, to ensure that the weld is flawlessly done. A job as a Gas 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.
