What does an assembly line operator do?
An assembly line operator builds a product at one station on a paced line. They fit parts in the set order and torque, follow the work instruction, use poka-yoke jigs, check their own work, and pass a good unit to the next station. They keep pace with the line and flag any bad part before it moves on.
What skills does an assembly line operator need?
An assembly line operator needs manual dexterity, the discipline to follow work instructions exactly, and the ability to keep pace with the line. Using torque tools and poka-yoke jigs correctly, spotting defects and maintaining safety and 5S at the station are all important. Reliability and steady attendance matter because the line rebalances around an empty station.
How do you become an assembly line operator?
Most assembly line operators start with a tenth pass or an ITI and learn the job on the line. Employers train new joiners on the work instruction and check points, then sign them off on the station. With experience and a good quality record, an operator can move up to line leader or quality inspector.
