Ceramic Ferrule

Ceramic Ferrule

Ceramic Ferrules for shear connectors Stud welding. Standard: BS EN ISO 13918 Type UF for weld shear connector to steel remembers directly. If you need for weld shear connector through metal deck.

Ceramic Ferrule is necessary part for shear connector Stud welding process it designed by the following functions:

  • Protection of the weld pool by creation of metal vapour in the burning chamber at sufficient current intensity.
  • Concentration and stabilization of the arc thus reducing arc blow.
  • Moulding of the displaced weld pool to a weld collar and supporting of the weld pool.

Furthermore it shields the operator from both arc and spatter. The ceramic ferrule is used for one weld only and is removed once the molten metal has solidified.

Stalwart Technosource India Pvt Ltd. ceramic ferrules with high precision size and low water absorption rate can significant improve the weld result.
