Abstract: | One of the main welding processes used in the industries for the purpose of fabrication of huge sized structures is Submerged Arc Welding process. The key features of this process are high deposition rates and long weld runs. The important process variables in submerged arc welding are: welding current, arc voltage, welding speed, nozzle to plate distance etc. The effects of these process variables are determined through their effects on weld bead geometry. Design of experiment using response surface methodology was used to conduct experiment and to develop relationship for predicting weld bead geometry, which enables to quantify the direct and interaction effects. The response factors, namely penetration, bead width, and bead height, as affected by arc voltage, current welding speed and nozzle-to-plate distance have been investigated and analysed. The models developed have been checked for their adequacy and significance by using the F-test and the t-test, respectively. ... |
