Welding is probably bit multi-modal. Traditional stuff isn't likely going away, but already there is already advanced robots for the job. Though it's unlikely they will be entirely AI controlled.
No doubt a lot of "assembly line" welding operations have already become highly automated. This is, however, already the area requiring lesser skilled and more easily replaced workpeople. I was thinking more about on-site and craft-associated welding which I imagine will continue to be highly valued until extremely portable and versatile high-DOF robotic manipulators become commonplace.
