Goerges, who has never been so far into a Grand Slam, showed no sign of nerves at all, despite a break-point in her first service game.
For the second time in three years, Williams will face Angelique Kerber for the title.
Also, the chance to demonstrate that she is still the very best in the business. Williams paused, realizing she, too, was getting ahead of herself.
Williams, seems to have taken the lead from her 10-month daughter in her approach to her comeback that has taken her to a 10th Wimbledon final.
Williams, who is in a major final just 13 matches into a stirring comeback, said, "This is insane, I don't know how to feel".
"A lot of people were saying, 'Oh, she should be in the final, '" the 36-year-old Williams said.
After hitting five aces with a serve that reached 119 miles per hour, delivering 16 winners to only seven unforced errors, and covering the court so well with speed and effort against Goerges, Williams will face another German, 11th-seeded Angelique Kerber, on Saturday.
"Whatever happens, honestly, it's an incredible effort from me and just good motivation to keep going for the rest of our career", Williams said.
In the final, Williams will play Angelique Kerber after the German's 6-3, 6-3 win over Jelena Ostapenko.
A second break allowed her to serve for the win at 5-1 and she had a match point, only for Ostapenko to find her range and stay alive.
Kerber is a former No. 1 and a two-time major champion, both coming in 2016 at the Australian Open and U.S. Open.More news: Game of Thrones racks up 22 Emmy nominations
If she beats Kerber on Saturday, Williams, who first won Wimbledon in 2002, will become the first mother to lift the Venus Rosewater Dish since Goolagong 38 years ago.
"I am a member, so that kind of counts".
Gorges was solid to start the second set as she held her first two service games again, but just as in the first, Williams broke through in the sixth. She's been excellent this Wimbledon, although it wasn't easy late against the stubborn Ostapenko.
"This is not inevitable for me". I had multiple surgeries and almost didn't make it when I gave birth. "I remember I couldn't even walk to my mail box, so it's definitely not normal for me to be in a Wimbledon final".
Williams took a 19-match Wimbledon winning streak into the day.
That title pushed her past Steffi Graf's record of 22 majors in the half-century professional era; Court won some of her Slams during the amateur era.
Leading 4-2, Williams powered into a one-set lead, breaking Goerges to love to move ahead. She won here I don't know how many times.
The American nearly bagged an early break despite Gorges racing to a 40-0 lead in her first service game. "I know that she is always pushing you to the limits to play your best tennis".
It took Kerber two tries to serve out the victory, getting broken to 5-2.
"I don't know if it's been the toughest, because I have Olympia. So do I", Williams said.
