Do I need to clone a webform?
Use Webform Share(https://www.drupal.org/project/webform_share) module to export &amp; import 

Example usage 1: Prepopulated webforms


Create a webform with the required components.
Export the webform
Edit the webform content type and paste in the content from the export (under Publishing options)
Use the standard node add content links and each new content item created should be prepopulated with the exported webform.
