A field-customizable inflatable purge dam apparatus for welding includes first and/or second inflatable purge bladders. A bridge conduit extends between the purge bladders. First and second quick-disconnect couplers are provided for detachably connecting the bridge conduit to the first and second purge bladders, respectively. The quick-disconnect couplers allow the bridge conduit to be selectively attached to, and detached from, one or both of the first and second purge bladders. The purge dam apparatus can be field-customized by combining the bridge conduit with one or more different purge bladders. Alternatively, the purge bladders may be selectively combined with one or more different bridge conduits. In another aspect, one end of the bridge conduit may be detachably connected to a single inflatable purge bladder, and the other end of the bridge conduit may be adapted to connect to a purge gas source. Various purge dam apparatus sub-assemblies may also be provided. |
