Microwave Cavity Welding: 6-Axis Robot + Modular Grippers, 4 Models on One Line, 99.5% Yield

From hand-welding microwave cavities at 92% yield with 4 separate lines, to a 6-axis robot welding line where stamping, punching, bending and welding chain end-to-end on one robot, 4 models share 1 line, changeover drops from 2 hours to 2 minutes, and yield locks above 99.5%.

Microwave cavity welding involves multiple processes — stamping, punching, bending, welding. Traditional manual flow runs four separate lines, with five workers each, two-hour changeovers, and yield wandering with worker feel. This video breaks down a fully automatic welding line where a 6-axis robot picks per vision-identified model, modular grippers swap like nozzles in two minutes, and welding parameters (current / voltage / speed) are locked per model so weld depth and strength stay consistent. The same modular-gripper-plus-flexible-robot pattern applies to oven inner liners, dishwasher liners, and sterilizer cavities.
