At present, the Narrow Gap Submerged Arc Welding is an advanced welding technology. As the weld is very deep and narrow, the slag is difficult to clean and will have impact on the quality of welding seam. Therefore, a new kind of narrow gap submerged arc welding slag cleaning device is designed to clean the welding slag. It is consisted of welding walking tractor, height adjuster, slag masher, slag cleaner and slag collector. The narrow gap submerged arc welding slag removal device used for the welding process can realize the cleaning that manpower cannot finish. It is a kind of time-saving, energy-saving and high efficient welding cleaning method.

In this study the fluxes of the submerged arc welding were designed with the help of ternary phase diagram CaO_SiO_2_Al_2 O_3 & CaO_TiO_2_Al_2 O_3 flux systems. Various combinations of flux constituents and caching parameters for performing submerged arc welding. Orthogonal array of Taguchi L9 were used for designing the flux. 3 variable of flux constituents were varied at three levels. Total number of 18 fluxes were designed for the study. 9 each for TiO2 and SiO2 based flux system. At open circuit voltage bead on the plate weld was performed i.e. 34Volt. By this study, an effort has been done to study/experiment the arc stability of SiO2 and TiO2 based flux system. Current and voltage transient were recorded by the use of high speed data procurement system. MATLAB 9 and Sigma plot 11 were used to plot the graph of time v/s voltage and current, to visualize the behavior of arc at different duration of weld for both types of flux systems. In SiO2 flux system, flux no 4 gave optimized results whereas in TiO2 flux system, flux no1 gave the better results.
