Feasibility test on calcium oxide-silica-calcium fluoride system with other consumables as the flux on spheroidal graphite (S.G.) core wire for multi-pass manual metal arc welding of S.G. iron base metal and malleable iron (M.I.) base metal has been carried out with a constant pre-heat of 500°C. Under similar conditions of welding, the same flux system on high carbon steel core wire has also been tried on M.I. base metal alone. Structure compatibility between the weldment and the base metal in as-welded condition was aimed at, by welding in a groove design used by Schaeffler and Schumbacker. The metallurgical factors involved in the welding process have been studied. The results obtained are promising and favourable. The structures obtained in the weldment are amenable to post weld heat-treatment and resulted in completely favourable microstructures.- A Study on the Solderability of Pure Nickel with Different Tin-Lead Solders using Resin and Zinc Ammonium Chloride Fluxes

Nickel and its alloys can be successfully soldered using tin-lead solders. For several engineering and electronic applications, either nickel and its alloys or other metallic materials coated with nickel are to be soldered. Even though the soldering practice for nickel has been in use for some years, data concerning systematic fundamental studies on the solderability of nickel with different solders and fluxes under different conditions of soldering are scarce in literature. In this work, an attempt has been made to study the effect of solder composition, nature of flux and soldering temperature on the efficiency of soldering and on the joint strength of butt and lap soldered joints of pure nickel.- A Note on the Spreading Characteristics of Some Tin-Lead Solders on Cast Iron
