Machine tending is, by far, the most popular application for collaborative robots. It’s a perfect fit for a cobot’s unique ability to work alongside or together with people without safety fencing.
That’s not to say, however, that process tasks, such as welding, cannot be done with cobots. They can. Granted, equipping a cobot with an arc-welding torch will require engineers to re-evaluate the notion of “inherently safe” operation. But, there are other advantages to using cobots for welding.
