Ceramic Ferrule for stud welding is normally with shear connector,it has many usage.
Protect the weld pool by create  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.

In this way, ceramic ferrule 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.Our ceramic ferrules with high precision size and low water absorption rate, can significant improve the weld result.
