Super force welding device?

Is it possible for somebody to make a welding gun that can force weld items together stronger than 5000? Has this already been done? It would be neat for creating buildings and stuff, since 5000 doesn’t seem like enough.

Use 0 as the value of the weld. It’s the same as infinite.

I want to make something that will fall apart, but not so easily. Not something indestructible, but something that you could shake a rocket launcher at. You know what I mean?

write in a custom value?
