Abstract
The paper contains a general description of the process of electric arc welding and discusses some of the general principles involved in this work. Some of the principal difficulties encountered in electric arc welding are described and comparison is made of its advantages over other methods of welding. The author concludes that there are very few cases of welding which cannot be more satisfactorily done with the electric arc than by any other means, provided the operator is sufficiently skillful. He also considers that less practise is required by operators to make successful electrical welds than is necessary with any other process. The paper concludes with some operating costs of different types of electric arc welding machines.
