Is it possible to "unweld" ultrasonic welds on plastics?
I do LED brake light conversions on car tail lights as a sort of hobby, and usually will just use a dremel to cut off the rear part of the tail light to do the conversion, and use epoxy resin to seal afterwards.
I know that some people just use a knife tip on a soldering iron and basicaly cut the rear off.
I heard from a friend today that it's actually possible to unweld the ultrasonic welds that bond the tail light cover to the rear housing, so that you get a clean disassembly. He mentioned something about putting some kind of liquid on the weld and that the housing would separate after a certain amount of time.
Has anyone heard of anything like this?
