Prediction and control of weld bead geometry and shape relationships in submerged arc welding of pipes
N. Murugan,V. Gunaraj +1 more
TL;DR: In this paper, mathematical models have been developed for SAW of pipes using five level factorial techniques to predict three critical dimensions of the weld bead geometry and shape relationships, and the models developed have been checked for their adequacy and significance by using the F -test and the t -test, respectively.
