Abstract

The Indian Institute of Welding completes its journey through 25 years for which all associated with it, directly or indirectly, can justifiably be proud of. The Institute has now grown adult and turned itself into one of the centres of assimilation and dissemination of informations on Welding Technology in this country. We must thank the founding fathers for their foresight and their pioneering efforts to make this happen.

The process of Indian Economic reforms appears to have considerably slowed down - thanks to the stock scam. On top of this monsoon which has been hesitant so far this year has added uncertainty so far as growth prospects are concerned.

Abstract

One would perhaps accord a guarded welcome to the new economic policies being persued by the Government, which has culminated in the 'Watershed' central budget and the new Exim policy. This has undoubtedly freed the economy from the inefficiencies of licence-permit raj and exposed the Indian industry to international competition.

Abstract

The completion of the general elections to the tenth Lok Sabha and formation of a Govt, under the leadership of Shri PV Narashimha Rao has set at rest, at least for the time being, the uncertainties- political, social and economic - tint had engulfed the country for more than a year or so. One only hopes that the tensions caused first by temple - masjid fiasco and then by tragic assassination of former Prime Minister Mr. Rajiv Gandhi would soon be replaced by sober socio-political tolerance by all cross-section of people.

The National Welding Seminar 1990 held in Bombay last November evoked tremendous response from all those who matter in the welding industry in India. The seminar can stand out as one of the finest in recent memory in respect of the richness of the subjects covered when one considers the depth and span of the knowledge and the interactions that have emerged.

Abstract

Energy costs have often been disregarded as being a minor part of the total welding co st.lt is discussed here that an inefficient power source consumes unnecessary extra energy which can be avoided by the right design and choice of the equipment.

There are also big differences in energy consumption between the welding methods & processes. Besides the energy costs, heat input also plays a major role with great significance for the metallurgical effects and thermal distortion.

On the macro level, one has to also consider the enormous savings in installation of new power stations apart from the adverse environmental effects of unnecessary power consumption. The problems with electromagnetic compatibility and the possible harmful effects from the electromagnetic fields on human beings is another issue.
