1. When should you choose rotation welding?

1.1 Prerequisites for choosing rotation welding

You will need :

• parts capable of rotating about an axis of revolution for at least one of the parts;

• a clean parting line (raw material) ;

• compatibility between materials;

• mechanically resistant parts to withstand :

  • the pressure required for weld adhesion,

  • torsion during rotation (previous phases) ;

• choose the parting line design :

  • two relatively flat surfaces,

  • a special profile...
