Suggestion: Learn to do welding of vacuum chambers. Think A&N corp, Kurt J. Lesker, etc. The welds have to be done on the inside of the chamber, then cleaned, and I have yet to see a good robot for this. The market is small enough that it may cost more to develop a good robot than it is worth. It also pays higher than standard welding. /used to hire a vacuum welder
