Building Better Pipe Faster at Less Cost by Shielded Arc Welding

This new bulletin published by The Lincoln Electric Company, Cleveland, Ohio, contains 14 pages 8-1/2×11 inches and is profusely illustrated with photographs of pipe lines under construction by electric welding. A brief forward reviews the progress of electric welding in pipe line construction from 1928 when the first major pipe line was electric welded up to the present time. A chart showing the percentage of electric welded line to the total lines built from the year 1928 to 1936 inclusive is given to illustrate the steadily increasing use of the process. Following the forward, there is a short explanation of the modern shielded arc process of electric welding together with a summary of tests of pipe welds made by this process. Reasons for the lower cost of pipe line construction with electric welding are indicated, by explanation of the modern shielded arc process of electric welding together with a summary of tests of pipe welds made by this process. Reasons for the lower cost of pipe line construction with electric welding are indicated by explanation of modern pipe welds made by this process. Reasons for the lower cost of pipe line construction with electric welding arc indicated by explanation of modern pipe line construction by the method. Data is given in tabular form on important aspects of welding of pipe lines. Tabulated data include recommended sizes of electrode for pipe line welding, average speed for shielded arc welding, recommended amperage and voltage for various sizes of rod, pounds of electrode per weld and recommended spacing for pipe.
