a proposal has been made to install an industrial robot toreplace the welder. The cell would consist of the robot, twowelding fixtures, and the fitter who loads and unloads the parts.With two fixtures, the fitter and robot would work simultaneously,the robot welding at one fixture while the fitter unloads and loadsat the other. At the end of each work cycle, they switch places.The robot would use gas metal arc welding instead of shielded-metalor flux-cored arc welding, but the welding speed would remain thesame 300 mm/min. The electrode wire spool must be changed every 10work parts, which takes 5.0 minutes and is accomplished by thefitter. Determine (a) arc-on time and (b) production rate for thiswork cell.
