Advice on welding hydraulic cylinder
Well I goofed up my wood splitter, was bringing back the wedge with a big piece of oak stuck to it (really stuck to it) and managed to booger the felmale side of the threads on the cylinder. Went a little too far lol. I was thinking of just welding a 1/2 nipple to it. Good idea or bad idea? I don't want to get any more metal in the cylinder trying to tap/helicoil etc but I don't want to trash anything with the heat either.

First, make sure you're using a steel nipple, not a cast iron one. Then wrap the end of the cylinder and the rod in wet towels. Have a few extra wet towels around so when you finish welding, you can re-wrap the end again. OR, use a hose to soak it down after you weld. Don't wet the nipple and cool it down too fast. What you're trying to protect is the gland in the end of the cylinder where the rod comes out. Make sure the rod is retracted all the way when you weld so the rod end/packing doesn't get too hot.

I was going to tell you to make sure it came out right, to use some beer but it looks like you already knew it.

Nah, I'll keep you posted when I'm throwing another log on the fire and the splitter is winterized in the garage, all my splitting is done for this winter. Its the return port anyways.

You must be an engineer. You can read the manual, but you can't read a picture. He welded to the nipple that was already stuck to the cylinder with an ordinary looking mig weld.

yes, I am. and I've engineered on pressure vessels for most of my career.
and yes, he welded to the nipple in the cylinder.
and do we know what the material is on the nipple welded to the cylinder?

Here's the thing.....
If it's a low-alloy steel, the nipple that's already been welded into the cylinder body, would face the same issues.
I don't see a splitter coming out of a factory with a safety issue like that built into it. I don't see their supplier sending out a cylinder with that issue, either.
What I would have an issue with, if it were my splitter, is the way the valve is hanging off that cylinder port. It's asking to be broke off again.
