Content	same trend for T.V. This graph shows T.V is maximum (64.2 mm3) when F is at its maximum value with S at its minimum limit. T.V is minimum (42.5 mm3) when F is at its lower value with S at its upper limit. Conclusions The following conclusions were drawn from the above investigation: 1) The five-level factorial technique can be employed easily for developing mathematical models for predicting weld bead geometry within the workable re- gion of process parameters for SAW of pipes. 2) The models developed can be em- ployed easily in the form of a program for automatic and robotic welding for ob- taining the desired high-quality welds. 3) The welding process variable wire feed rate has a positive effect, but weld- ing speed has a negative effect on all the bead parameters. 4) Penetration reduces as welding voltage increases, but bead width and di- lution increase considerably with the in- crease in voltage. 5) Reinforcement is least when all the process variables are at their upper limit (+2) and F is at its lower limit. 6) Nozzle-to-plate distance has a neg- ative effect on all the bead parameters ex- cept bead width and total volume of the weld bead. 7) Most of the direct and interaction effects of the process variables on the bead parameters show generally con- vincing trends between cause and effect.
