Merge two text files (oh no, not again!)

Hello,

I'm new to this forum. I have always made good use of all the wise hints shown here. But this time I'm struggling with an issue that is driving me crazy.

I have two text files, I have to merge them based on the first column, resulting file must contain all record from the first file AND all records from the second one.

Code:
RB-4.762/G10Q M1         04763-010M01R3-01       ;         ;         ;         ;  2744000;
