PF-Ceramic Ferrules
Place of Origin: China (Mainland)
· Type: Ceramic Ferrules for PD type welding studs

· Brand Name: Solid ceramic ferrules
Ceramic Ferrule is necessary part for drawn arc 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.
Solid ceramic ferrules with high precision size and low water absorption rate, can significant improve the weld result.
