Merge and matching tables in Oracle - oracle

Question

Does anyone know how to merge two tables with a common column name and data into a single table? The shared column is a date column. This is part of a project at work, no one here quite knows how it works. Any help would be appreciated.
table A
Sub Temp Weight Silicon Cast_Date
108 2675 2731 0.7002 18-jun-11 18:45
101 2691 3268 0.6194 18-jun-11 20:30
107 2701 6749 0.6976 18-jun-11 20:30
113 2713 2112 0.6616 18-jun-11 20:30
116 2733 3142 0.7382 19-jun-11 05:46
121 2745 2611 0.6949 19-jun-11 00:19
125 2726 1995 0.644 19-jun-11 00:19
table B
Si Temperature Sched_Cast_Date Treadwell
0.6622 2542 01-APR-11 02:57 114
0.6622 2542 01-APR-11 03:07 116
0.7516 2526 19-jun-11 05:46 116
0.7516 2526 01-APR-11 03:40 107
0.6741 2372 01-APR-11 04:03 107
0.6206 2369 01-APR-11 09:43 114
0.6741 2372 19-jun-11 00:19 125
the results would look like:
Subcar Temp Weight Silicon Cast_Date SI Temperature Sched_Cast_Date Treadwell
116 2733 3142 0.7382 19-jun-11 05:46 0.7516 2526 19-jun-11 05:46 116
125 2726 1995 0.644 19-jun-11 00:19 0.6741 2372 19-jun-11 00:19 125
I would like to run a query that returns a results data only where Sched_Cast_Date and Cast_Date are the same. A table with the same qualities would work just as well.
I hope that this makes more sense.

Are you asking how to join two tables on a common column? i.e.
select a.Sub, a.Temp, a.Weight a.Silicon a.Cast_Date, b.SI,
b.Temperature, b.Sched_Cast_Date, b.Treadwell
from a
join b on b.sched_cast_date = a.cast_date
