Hello, I’m new on this devforum, I have these problems for 1 year now.
So I really want someone to help with this.
It’s really annoying for me.

When I place down the brick or part, It going to adding weld itself.
I dont think it is possible. This is like an automatic feature for roblox. Im annoyed by it myself. My car wont move sometimes because the wheels are welded.
In the Home tab click the Join Surfaces button.
I think I know the fix for this! In your Studio, check out the “Model” tab. Then, find “Join Surfaces.” Disable that and everything should work OK.
Hope this helps!
I never knew that it “Join Surfaces” 
But Thanks! this thing is solving my problem.
in the home tab like where is that you mean when you load up Roblox studio or like this doesn’t help at all, I don’t understand
Yeah, it keeps adding many welds when editing or duplicating a part
