RE: Weld neck flange
There are no hard and fast rules, so just about anything you want to weld to it, provided you observe the basic dimensions shown in API6A. You can transition up or down in size, if you comply with the requirements shown for Welding Neck Flanges.
Materials are another matter. Materials requirements tend to vary from application to application. What pressure/temperature class will you be working with? Which piping material is specified? What does your weld procedure require?

RE: Weld neck flange
So A105 might be ok. Depends on your design code and design pressure. It doesn't have to be 10000 psi,
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
