Webform Localization does not work I have downloaded the Webform Localization module from Drupal.org, but it is not working to translate form, and I want to keep a single webform across all nodes. 

How can I do that?
If you create webform first and then install webform localization module , the module will see only new components in webform , so try to open each component and save it then go to Regional and language > translate interface > strings , check "webform localization" and "fields" then "Refresh strings" , then back to translate interface > translate , search for your components labels and translate them
