I'm building a simple muzzle loading pistol, and I was just curious about this. I am threading a breech plug, but is there any particular reason I can't screw it in and then weld it too?
Welded breech plug?

Black Powder cannon's bore is .472" firing a .452" ball.
If the weld is not in the pressure area, it will work for sure. Took a galvanized pipe and cut a 1" long rod to fit tighly into the pipe. Then had a welder braze the back end. The powder charge is 1" away from the weld.

You can.
But, I'm not sure there is any need too.
I made a .36 cal pistol in High School shop in 1962, and just threaded the breach plug, in case I ever needed to take it out again.
It withstood three double charges of FFFFG powder and double ball Proof Loads with no problem.
And it's still together 50+ years later.
I can't remember the thread I used, but probably 3/8"x 24TPI.
We worked on tractors more then guns so tooling was limited!

If the job is done properly there is absolutely no reason to weld it. Also, if it is welded you will have a heck of a time removing it should the need occur in the future, something I do regularly when inletting the barrel on the stock.

If all you're going for is to ensure that it wont back out, it'd be easier and less permanent to peen it at one or two points.

There is even no need for that.
A properly fitted threaded breech plug simply cannot back out while held in place from turning by the stock.

If you weld the breach plug in, sometime in the future you will want to take it out.

Are you "chasing" the threads on the breachplug using a lathe?
If so, cut the threads a little on the tight side so that a wrench will be required to tighten/ loosen.
I don't think a weld is necessary!
