How do i weld multiple Parts?

As Void_Frost said, this site is not a request site. Do not come here expecting us to write you code or do things for you without you trying or at least making an attempt to learn.

Though, I do believe that we here at Scripting Helpers have an obligation to answer most questions (some exceptions), in a way that positively educates and motivates the Asker to further learn.

Here are Wiki resources that will fully aid and guide you to reach your goal:

Instance

Function

Loops

:GetChildren()

Tables

Weld

Using the above articles, if actually thoroughly read, will help you easily accomplish your goal.

Hope this helps! In the future, please at least attempt to research resources yourself before posting a question.

look at this and change it accordingly

if have questions like that, go to roblox wiki.
