Application
Spot Welding
Robotic spot welding drives a servo weld gun through a sequence of resistance welds on sheet metal assemblies. It remains the backbone of automotive body-in-white production.
A spot welding robot carries a weld gun, either pedestal-mounted or servo-driven on the arm, and cycles through dozens of weld points per body panel with millimeter-level repeatability.
Payload requirements are higher than most applications because the robot has to move the gun's own mass, often 100 kg or more, in addition to any transformer weight on the arm.
Weld timer and gun controller integration is tight. The robot signals squeeze, weld, and hold phases, and cell throughput depends on how well robot motion and gun electrode timing are synchronized.
