A welded return line is usually just a welded in bung, and then the line threads into that. You can always just unscrew it for easy disassembly- while at the same time the welded connection goes a long way to stop leaks.
The jury is still out on how well the "weldless" return bung works. I have seen some have trouble, and others none at all. The difference seems to be a mixture between luck and how well it is installed.
