An examination will show that the greatest usefulness of this book lies in
the fact that all necessary information and data has been included 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.
An effort has been made to eliminate all matter which is not of direct
usefulness in practical work, while including all that those engaged in
this trade find necessary. To this end, the descriptions have been limited
to those methods and accessories which are found in actual use today. For
the same reason, the work includes the application of the rules laid down
by the insurance underwriters which govern this work as well as
instructions for the proper care and handling of the generators, torches
and materials found in the shop.
Special attention has been given to definite directions for handling the
different metals and alloys which must be handled. The instructions have
been arranged to form rules which are placed in the order of their use
during the work described and the work has been subdivided in such a way
that it will be found possible to secure information on any one point
desired without the necessity of spending time in other fields.
The facts which the expert welder and metalworker finds it most necessary
to have readily available have been secured, and prepared especially for
this work, and those of most general use have been combined with the
chapter on welding practice to which they apply.
