Describes non-destructive examination practices, visual inspection criteria, welder qualification tests, and the importance of quality workmanship SMAW-Equipment and Setup 5 Hours Describes SMAW welding and welding safety. Explains how to connect welding current and setup arc welding equipment. Each section is composed of one or more chapters that describe processes, explain procedures, or present general information relating to the topic of that section.

A section can be studied independently or in sequence with other sections. The fi rst section provides general information about welding. The topics presented in these chapters include welding careers safety an overview of welding and cutting processes a brief discussion of the physics behind welding information about welding-related math, measurement, and layout a close look at the different weld joints and welding positions and information about drawings and welding symbols.

Sections 2—8 present detailed information about welding and cutting processes. This study of processes begins in Section 2 with a close look at shielded metal arc welding. The subsequent sections present detailed information about gas metal and fl ux-cored arc welding, gas tungsten arc welding, plasma arc cutting, oxyfuel gas processes, and resistance welding. The fi nal section discusses technical information that is of practical importance to welders.

The topics covered in these chapters include pipe and tube welding, special welding and cutting processes, robotics in welding, inspecting and testing welds, and welder certifi cation. The end of the book contains several useful appendices and an extensive glossary of technical terms. You may begin your study of welding with any section and progress in any desired sequence from section to section.

In a first step, DFM methods intend to assist the manufacturing process and material selection, and in a second step, they seek to improve the design to optimize manufacturing costs. Traditional DFM methods are those assessing part-manufacturing difficulties. Therefore, the focus is on optimizing the design for individual production processes, such as casting, stamping, injection molding and machining processes. Cost estimation models have also been developed as DFM quantitative tools to evaluate manufacturability [ 6 , 9 ].

Some of these methods are feature-based evaluation tools. Cost indices are provided for processing the different features using parametric models and a library of manufacturing knowledge bases. Although DFM has traditionally been focusing mainly on part forming processes with regard to welding, Schreve et al.

This cost model uses a times and rates approach but does not focus on output quality. In the methods described above, the type of products in which DFA and DFM are usually applied are those that can be complex in geometry and that contain large numbers of parts. However, in these products, geometry is not highly linked to functionality. This fact allows easy geometrical modifications to solve manufacturing difficulties, as well as product structure modifications to solve assembly difficulties.

These actions are aimed at reducing time and cost during production. Nevertheless, as mentioned in the introduction, welded aircraft structures are products made of geometries closely linked to functionality.

Thus, manufacturing variation in key product characteristics becomes a critical issue. Therefore, for this type of application, producibility criteria cannot solely rely on the time and cost spent during the manufacture and assembly but also on the quality built into the product, as suggested by the authors in previous studies [ 33 , 34 ]. The objective then becomes to reduce quality-related failures during production, thereby minimizing rework costs.

Under the umbrella of quality, recent research in the area of variation management has been focusing on reducing quality failure and related costs [ 15 , 35 , 36 ].

Welding is a high-tech industry that can take you places all over the world.

From ladders to aircraft carriers, from NASCAR to national defense, and from the laboratory to sales and repair, the varied welding industry impacts virtually every industry. Technology is creating more uses for welding in the workplace. For example, new ways are being developed to bond dissimilar materials and non-metallic materials, such as plastics, composites, and new alloys. Also, advances in laser beam and electron beam welding, new fluxes, and other new technologies and techniques all point to an increasing need for highly trained and skilled workers.
