It looks like you'll want something like this:
INSERT INTO Table3
(part_num, prt_name, desc1, desc2,
cat_num, cat_name, sdesc1, sdesc2)
SELECT COALESCE(T1.part_num, T2.part_num),
T1.prt_name, T1.desc1, T1.desc2,
T2.cat_num, T2.cat_name, T2.sdesc1, T2.sdesc2
FROM Table1 AS T1
FULL JOIN Table2 AS T2
ON T1.part_num = T2.part_num ;
It still seems at least questionable whether Table3 or even Table2
represent "good" designs but as I only have your column names to go on
there isn't much point in me speculating about that.

Whenever possible please post enough code to reproduce your problem.
Including CREATE TABLE and INSERT statements usually helps.
State what version of SQL Server you are using and specify the content
of any error messages.
