Subject field(s)
  • Joints and Connections (Construction)
  • Plastics Manufacturing
OBS

Extrusion (or fusion) welding is used exclusively on HDPE [high density polyethylene]. It is a direct parallel of metallurgical welding in that a ribbon of molten polymer (instead of metal) is extruded between the two surfaces to be joined. The electrode causes some of the sheet material to be liquefied and the entire mass then fuses together.
