Welding Productivity and Economy

Abstract

The weldwg group of the National Committee on Science and Technology (NCST) reports that in India, presently 95% of the total weld metal deposited is by Manual Metal Arc Welding (MMAW) using coated stick electrodes and forecasts that even after 10 years from now, this will remain at 90%.

In this context, this paper briefly explains some of the factors that will contribute for improving productivity and bringdown the cost of welding by MMAW process.
