Application
Arc Welding
Robotic arc welding uses a torch-mounted arm to run MIG, TIG, or flux-core welds with consistent speed and angle. It is the highest-volume robotic welding application in general fabrication and automotive.
Arc welding robots move a torch along a programmed or sensor-corrected seam while a wire feeder and power supply control the weld puddle. Consistent travel speed and torch angle produce uniform bead geometry that is hard to match with manual welding over long runs.
Most cells pair the robot with a positioner that rotates or tilts the part so welds stay in the flat position, and with through-arc or laser seam tracking to correct for part-to-part fit-up variation.
Duty cycle matters as much as payload. The torch, cables, and wire feed system need to survive continuous arc-on time without overheating, and the arm needs hollow-wrist cable routing to avoid snagging in tight fixtures.
