Blueprint Reading for Welders

The fourth edition of Blueprint Reading for Welders provides a detailed interpretation of the welding symbols as presented in the American Welding Society Standard A2. 4-86 Standard Symbols for Welding, Brazing and Nondestructive Examination. The engineering drawing is the medium vy which the engineer/designer conveys information to machinists and welders. To use the drawing, the welder is required to understand both conventional drafting symbology and specialized welding symbols. The text begins with simple drafting concepts and sketching techniques, then covers the metal structural shapes commonly used by welders. More advanced drafting techniques are described, including auxiliary views, detail views, projections, sections and detail and assembly drawings. Once the learner is familiar with basic drafting concepts and components of drawing, the welding symbol is introduced. The balance of the text examines the weld symbol, its representation on a drawing, dimensioning requirements, and specific meaning in different situations. An entire unit is devoted to explaining basic joints for weldment fabrications. Other topics explained in detail include pipe welding symbols and their application, applied metrics and dual dimensioning, and inspection testing. The appendix section includes updated specification sheets for structural metal shapes, including pipes, and tables for converting decimal, fractional, and whole inches to millimeters. Folded tear out drawings at the back of the text reproduce selected assignment drawings in a larger size.
