Question

Chapter 29 Welding Processes-Fundamentals of Modern Manufacturing 6th

29.2 (SI units) In the previous problem, a proposal
has been made to install an industrial robot to
replace the welder. The cell would consist of
the robot, two welding 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 loads at the other. At
the end of each work cycle, they switch places.
The robot would use gas metal arc welding
instead of shielded-metal or flux-cored arc
welding, but the welding speed would remain
the same 300 mm/min. The electrode wire
spool must be changed every five work parts,
which takes 4.0 minutes and is accomplished
by the fitter.

Determine (a) arc time and
(b) production rate for this work cell.
