Weldable plastic materials for fabricated tanks, benches, and cabinets

Welding is an economical method for joining compatible plastic sheets in fabricated assemblies. Common weldable plastics include HDPE, PVC, polypropylene (PP), and PVDF, which are often used where like materials need to be joined into tanks, cabinets, wet benches, and other fabricated plastic structures.

Plastic sheet welding methods include hot gas welding, extrusion welding, and butt welding. If welding rod is used, it should be compatible with the polymer being joined. Some plastics may also need to be welded in a nitrogen atmosphere to help prevent oxidation. Welded plastic assemblies are common in chemical handling, industrial equipment, and semiconductor and electronics manufacturing applications.
