Many hours have been spent in welding the various parts together that make up the total sheet metal system. Managing the welding operation of the contractors business is a vital part of the total operation. Back in the early ~O S, heet Metal and Air Conditioning Contractors' National Association, Inc. (SMACNA) seeing the need for more information and guidelines published the first edition of the manual. It was out of an out growth of concerns that the sheet metal contractor was in need of more specific guidelines on the welding operation. The first edition attempted to collect information from the various facets of welding as it applied to the sheet metal business, but from the non-expert perspective. It was recognized that the manager had to be able to make business udgements and needed the tools to help in the process. Things such as weld productivity, quality, equipment selection, training, hiring, estimating, process, standards and safety were examined from the managers prospective. The purpose of the new edition as in the past was to provide the sheet metal manager with the tools to manage the welding operation of the business. In the last decade there have been changes that have effected the welding operations in many respects. The Welding Committee of SMACNA developed this new edition after reviewing the needs of the Contractor and revised the guide to reflect the latest technology and methods. It was hoped that the revised guide will help Contractors managing their welding operation more profitably. This edition includes updated coverage for welding processes such as submerged arc; flux cored wire guidelines; power supplies and spool guns. An expanded safety chapter cover such item as health effects, hazards, controls, and OSHA. The latest methods of joint design are included with updated figures and drawings. New guidelines for developing a welding procedure are provided in the chapter on standards, codes and specifications. Weld quality is updated and includes coverage for burn table applications. Estimating is expanded and provides both a short and long method of estimating welding cost and examples are given. Welder training is updated and covers the Nation Training Fund (NTF) program and welder qualification. Integration of the metric standards are incorporated into the text using a soft conversion. Welding in the sheet metal business is a joining process that is part of the contractors' operation and it is a significant pari of the business. SMACNA through its welding committee working with members, chapters, and the welding industry is committed to providing sheetmetal contractors with guide-lines for managing their welding. SMACNA sincerely appreciates the contributions of the welding industry and the input of concerned and interested individuals.
