Procedure Control of Fillet Welds

The Sputniks, Flying Saucers and atomic reactors have excited people all over the world, but their fabrication problems have only been solved by the use of welding. Even in such an age there had unfortunately been a stop-gap of a few years in application of welding in important constructional work, such as, bridge girders, etc. This seemingly, brought a disapointment amongst WELDING ENGINEERS in the country. At the time it appeared, that welding industry as a whole and application of welding in constructional work in particular had been set back. It also appeared that as a result of this, progress in science and technique of welding would lag behind that in other countries. In 1954, it was a fortunate incidence that construction of a Road-cum Railway Bridge over the River Ganga at Mokameh was proposed and taken in hand. Constructional engineers all over the world were interested in it and submitted alternative designs of the superstructure in partly rivetted and partly welded construction. The competition in saving of steel was so keen that each designer had to devise means to use steel to the barest minimun. To fulfil this condition in their design, they had to adopt welding as a major tool of fabrication. Finally, a design was adopted with the majority of members in the main girder of H. T. Steel in rivetted construction and a few members of the main girders and the entire floor systems of mild steel in welded construction.
