Excerpt from A Text Book on Welding and Cutting Metals The oxy-acetylene welding and cutting torch has become so popular in the last few years, that almost every issue of the trade papers in any branch of work contains interesting accounts of new successes in the use of this powerful tool. The first application of the process, to commercial use, dates back to 1903, and its rapid growth in popularity is due to the ease and economy with which its intense heat 15 applied to any of the metal trades, to join two pieces by welding, or separate them by cutting without the stroke of a hammer. A notable example of the saving that may be effected by using this process is in the event of repairing a broken loco motive cylinder shown in Fig. 1. This cylinder had a piece broken out of the wall including a portion of the flange. Previous attempts to weld this piece in place by other methods had proven disastrous, and resulted in making the fracture larger. The oxy-acetylene process was then 'brought into use, and in less than a day's time a new piece was welded in as shown in Fig., 2. The cylinder was rebored, drilled, and the job finished without removing it from the locomotive. A great sawing in this case is credited to the fact that the loco motive was put back into service in a comparatively short time, and the repairs were made without dismantling. The durability of this work 1s illustrated in fact that this cylinder was welded July loth, 1910, and is still in successful operation.

Excerpt from A Text Book on Welding and Cutting Metals It is only a short time since the second edition was issued, and it is gratifying to find that the supply is nearly exhaused. There are many mechanics and autogenous welders who desire short, clear and practical instructions on the subject of acetylene welding and it is the purpose of this book to fill this demand. A comprehensive treatise on this subject would necessarily include much technical material that would he useless to the practical man who wishes to acquaint himself with only enough theory to thoroughly master the performance of his duties. and for this reason we have excluded nearly everything of a strictly technical nature. The Chapters on chemistry. physics and metals are of the most elementary nature, and cover in the plainest language only the subjects that are vital to the welders information. At the same time they are sufficiently explicit to give him a thorough working knowledge of the subjects that pertain to his work. In compiling these pages we have consulted the works on the Manufacture and Properties of Iron and Steel. By II. II. Campbell. The Metallurgy of Iron and Steel, by Bradley Stoughton, and Autogenous Welding, by Granzon and Rosemberg: and some of the text relating to generators and welding has been condensed from papers which we contributed to a few of the leading magazines.
