Effect of welding parameters on the corrosion behavior of underwater wet welds with new oxyrutile WW70 and commercial rutile E6013 electrode

Journal of Materials Research and Technology
In this work, the corrosion resistance of underwater wet welds produced with the new oxyrutile electrode Wet Weld 70 (WW70) was investigated, under different welding currents and depths in DCEP, and compared with the commercial rutile electrode E6013 ...

Effect of Welding Parameters on Weld Bead Shape for Welds Done Underwater [PDF]

International Journal of Mechanical Engineering and Applications, 2014
The desire to model a control system so as to optimize the welding process parameters and the effect of the environment during underwater wet welding makes it necessary to study the effects of these parameters as it affects the weld bead geometry of welds achieved in underwater welding. The objective of this paper is to analyze how welding arc current,
