Soldering 2" copper with propane

[Kenny8906]

Hello, I'am curious if a LP torch is sufficient enough to solder my 2" copper column, or do I need to get a MAPP torch. I've solder 1/2 & 3/4 copper serval times but wasn't sure if the LP would put out enough heat for the 2". BTW I am new to the forum, although been lurking around for a couple months soaking in all the reading. I thank everyone for their input.
