Use wireshark's "mergecap" utility, or in Wireshark's GUI go to File -> Merge, load the second file into the first, and save it as a new combined file. In both cases you have options, but the default (suggested in this case) is a chronological merge on packet timestamps.

Edit: If you're doing this each hour, I definitely suggest a "mergecap" command line statement scripted to run when the hourly capture files are finished.

Uhm, better yet, why don't you capture into a single file on both cards at the same time? Wireshark/dumpcap support capturing from multiple NICs since version 1.8., so there's no need to merge afterwards.
