Freestyle Dry pipe repair?

Ok so the I the day I thought I blew a coupler. But... When I pulled the chamber off today to change the coupler I found that the part of the chamber that has the orings on it was broke off in the manifold. I can weld aluminum but don't know if you could ever get it clean enough to burn in good. Any one seed this? What are my options? This is a riva freeride pipe by the way.
