Electrode Negativity in Submerged Arc Welding by Ajit Kumar Naik is a document available to read on EtoBox.
The study investigates the effects of electrode negativity (EN) ratio, current, and welding speed on bead profile and arc stability during submerged arc welding of API X80 steel. Results indicate that increasing the EN ratio and welding current reduces the deleterious hump angle and increases the average prior austenite grain size, impacting the microstructure and hardness of the coarse grain heat affected zone. Arc stability analysis using probability density distribution graphs shows improved stability at
