So I working to restore my headlights and the tops are severly cracked, broken and missing pieces. Im working to weld the cracks and fill in the material with new brass. I'm learning as I go, any advice would be apperciated.

Sometimes things are too far gone to warrant repair.
That being said cracked brass should be silver soldered. To me it looks like you are attempting to braze the parts in the photo. I won't say that it can't be done but what I see looks like a lesson in frustration.
Try doing a search on this forum on brass restoration. It has been discussed here many times. I remember trying that myself a long time ago

You can't braze what isn't there, I said "weld" instead of braze due to the fact that is is brass on brass instead of brass on steel or cast. Actually it isnt going that badly, cleanup will be a bit of work. I would like to buy new pieces but haven't sourced them yet.

Chadwick: you may try "backing up " the workpiece with a piece of aluminum ...this will allow the brass to puddle against the aluminum and not simply fall thru ...always an optimist ...gene french

Good advice, thanks. So far Ive only had 1 drop fall thru.

If the brass is simply missing, get some sheet stock the same thickness and fit it tighty in the space and silver solder it in. Silver solder melts at a much lower temperature than the brass, and finishing it will be much easier. Cleaning up all that "weld" is going to be quite an undertaking.

While you are making these whole again, keep your eyes on ebay, they do come up every so often.
