It prepares and orients you to the basic as well the advanced. It contains all necessary information and data in one volume, making it possible for the workman to use one source for securing a knowledge of both principle and practice, preparation and finishing of the work, and both large and small repair work as well as manufacturing methods used in metal working. With almost a hundred illustrations, the 50,084-word Welding Course will guide you step-by-step towards learning the art and craft of joining and cutting metals...\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003ePREFACE\u003cbr\u003e\u003cbr\u003eIn the preparation of this work, the object has been to cover not only the\u003cbr\u003eseveral processes of welding, but also those other processes which are so\u003cbr\u003eclosely allied in method and results as to make them a part of the whole\u003cbr\u003esubject of joining metal to metal with the aid of heat.\u003cbr\u003e\u003cbr\u003eThe workman who wishes to handle his trade from start to finish finds that\u003cbr\u003eit is necessary to become familiar with certain other operations which\u003cbr\u003eprecede or follow the actual joining of the metal parts, the purpose of\u003cbr\u003ethese operations being to add or retain certain desirable qualities in the\u003cbr\u003ematerials being handled. For this reason the following subjects have been\u003cbr\u003eincluded: Annealing, tempering, hardening, heat treatment and the\u003cbr\u003erestoration of steel.\u003cbr\u003e\u003cbr\u003eIn order that the user may understand the underlying principles and the\u003cbr\u003ematerials employed in this work, much practical information is given on the\u003cbr\u003euses and characteristics of the various metals; on the production, handling\u003cbr\u003eand use of the gases and other materials which are a part of the equipment;\u003cbr\u003eand on the tools and accessories for the production and handling of these\u003cbr\u003ematerials.\u003cbr\u003e\u003cbr\u003eAn examination will show that the greatest usefulness of this book lies in\u003cbr\u003ethe fact that all necessary information and data has been included in one\u003cbr\u003evolume, making it possible for the workman to use one source for securing a\u003cbr\u003eknowledge of both principle and practice, preparation and finishing of the\u003cbr\u003ework, and both large and small repair work as well as manufacturing methods\u003cbr\u003eused in metal working.\u003cbr\u003e\u003cbr\u003eAn effort has been made to eliminate all matter which is not of direct\u003cbr\u003eusefulness in practical work, while including all that those engaged in\u003cbr\u003ethis trade find necessary. To this end, the descriptions have been limited\u003cbr\u003eto those methods and accessories which are found in actual use today. For\u003cbr\u003ethe same reason, the work includes the application of the rules laid down\u003cbr\u003eby the insurance underwriters which govern this work as well as\u003cbr\u003einstructions for the proper care and handling of the generators, torches\u003cbr\u003eand materials found in the shop.\u003cbr\u003e\u003cbr\u003eSpecial attention has been given to definite directions for handling the\u003cbr\u003edifferent metals and alloys which must be handled. The instructions have\u003cbr\u003ebeen arranged to form rules which are placed in the order of their use\u003cbr\u003eduring the work described and the work has been subdivided in such a way\u003cbr\u003ethat it will be found possible to secure information on any one point\u003cbr\u003edesired without the necessity of spending time in other fields.\u003cbr\u003e\u003cbr\u003eThe facts which the expert welder and metalworker finds it most necessary\u003cbr\u003eto have readily available have been secured, and prepared especially for\u003cbr\u003ethis work, and those of most general use have been combined with the\u003cbr\u003echapter on welding practice to which they apply.\u003cbr\u003e\u003cbr\u003eThe size of this volume has been kept as small as possible, but an\u003cbr\u003eexamination of the alphabetical index will show that the range of subjects\u003cbr\u003eand details covered is complete in all respects.
