7. CONCLUSION
In this study, a automatic robotic arc welding system has been deigned to study the effect of welding speed on
the depth of penetration and the deepest depth of penetration obtained is 4.4 mm at the speed of 110.43 mm/min.
Hence it can be concluded that increasing the speed of travel and maintaining constant arc voltage and current will
increase penetration but at an optimum speed, penetration will be maximum. The welding torch speed has to be
fixed at this speed to attain maximum penetration otherwise results decrease in penetration. Finally it is
concluded that robotic arc welding system is capable to maintain the arc length and welding speed to get the
weld quality.
