Editorial

In this issue we have two papers on joining of non-ferrous metal and alloys-one from the group of Dr. G. Madhusudhan Reddy who are all most regular contributor to IWJ and other from the group of Dr. V. Balasubramanian who are also equally contributing to IWJ. The paper on "Studies on partially melted zone and pitting corrosion resistance of A 356 aluminium-silicon alloy GTA welds" is of practical importance as the suitability of available techniques in improving weld performance is always demanded by the industries. Furthermore, the corrosion resistance affected by microstructural aspects of Al-Si welds would be interest to the researchers as well.
