As the head of the technical service department of his firm, Mr. Nadkarni's job was to advise customers on the correct use of welding. This involved visiting welding shops all over the country and discussing welding jobs and problems with the technical men concerned. Over the years, he has gathered experiences, some amusing and some distressing, which arose from popular fallacies regarding welding. Some of the fallacies die hard, others get removed in course of time as men gather experience or new men specialised in Welding take over. In the course of this short lecture, he dealt with a few of those fallacies, which gave rise to a lively constructive discussion.- "Standard Procedures in Manual Arc Welding"

WELDING PROCEDURE is defined in IS: 812-1957, "Glossary of Terms relating to Welding and Cutting of Metals", as a 'specified course of action to be followed in welding, including a list of materials and tools to be used'. The welding procedure must be planned well in advance, taking into consideration the existing standard codes and specifications wherever they are applicable and with an understanding of the various types of electrodes and equipment available or necessary for the job, and, finally, in consultation with the men on the shop floor. A well-planned procedure ensures a most economical and efficient welded fabrication, and, in the case of a production job, consistent quality of production.- Mild Steel Weld Metal

Mild steel weld metal is an important engineering material on which depends the overall strength and efficiency of welded fabrications in mild steel such as pipelines, bridges, ships, boilers, penstocks and locomotive fireboxes. In manual metallic arc welding, the weld metal is deposited from an electrode by the fusion of its metallic core wire in the electric arc formed between the electrode and the work-piece. The flux covering of the electrode also melts in the arc and provides slag that refines and modifies the weld metal and forms a solid blanket over it on solidification.
