How do you design and program a robotic welding cell for automotive production?

Robotic welding cell design involves: Process requirements analysis (weld types, cycle time, quality targets), Robot selection (payload for torch and wire feeder, reach, axes configuration), Welding equipment integration (power source communication, wire feed system, torch maintenance), Positioner design (2-axis, headstock-tailstock for optimal weld positions), Fixture design (locating accuracy, clamping, anti-spatter), Safety system design (light curtains, interlocks per ISO 10218), Offline programming and simulation (robot path, collision avoidance, cycle time), Weld parameter database (WPS for different joints/materials), Seam tracking implementation (through-arc or vision-based for variation), Quality monitoring integration (arc data, vision inspection), and Cell controller/HMI development. Target OEE >85%, weld quality Cpk >1.33. Include error recovery procedures and operator training.
