The Importance of Internal Collar Plug Welding for Screws

Conveyor screws are designed to handle torque. If plug welds between the center pipe and internal collar fail, the screw will fail causing an interruption to production. KWS provides four plug welds per bushing, with two plug welds located on each side at 180-degrees apart. Plug welds provided on KWS screws are permanent and guaranteed for life.
