Synopses & Reviews
Welding is a crucial manufacturing technique in creating countless numbers of commonly used items. From buildings to bridges and cars to computers, many of these items would be virtually impossible to produce without the use of welding.
Welding Processes Handbook is a concise, explanatory guide to commonly used and commercially significant welding processes. It describes processes and equipment applicable to all instruction levels, and takes the novice or student through the individual steps involved in each process in a clear and comprehensible way. Topics such as welded joint design, quality assurance, and costing are all covered in detail.
The handbook provides an up-to-date reference on the major applications of welding as they are used in industry. It is poised to become the leading guide to basic welding technologies for those new to the industry.
