ABSTRACT:
The present invention is directed to a welding tip for welding polymeric materials such as containers. The welding tip includes a cylindrical body. The cylindrical body defines a central bore and includes a perimeter around the bore. The perimeter includes one or more knurls. The knurls provide the welding tip with varying temperatures and pressure points to create a more desirable weld.
