Ceramic Ferrules For Stud Welding

Used for multiple purposes in stud welding.

Ceramic ferrules for stud welding.

First the ferrule helps to shield the arc from the operator. Because of this manufacturing method ceramic ferrule tolerances can be greater than machining or. Ceramic ferrules are essential part of the standard shear connectors shear studs drawn arc stud welding process. Initiating the welding process.

Ferrules are disposable items. By means of a lifting mechanism the stud will be lifted and at first an auxiliary arc pilot arc of a low current will be drawn. Without ceramic ferrules the drawn arc process wouldn t be effective and welds wouldn t be as strong. The use of a ferrule is required for stud welding in order to concentrate the heat and retain the molten metal at the base of the stud until it has cooled.

The stud will be inserted into the chuck of the stud welding gun and positioned onto the workpiece possibly by adding a ceramic ferrule. Our ceramic ferrules can go from ambient temperature to weld temperature in a split second and resist cracking or exploding. Ferrules are cast in a mold out of a low grade moldable ceramic. Third the ferrule forms the molten metal into the fillet.

Why are ceramic ferrules essential for stud welding. They are taken out of the mold and are dried. After cooling the ferrule is broken off to reveal the weld. As disposable items they are mass manufactured quickly and inexpensively.

Ceramic ferrules for arc stud welding are disposable items. In the process the shear connector will insert into the center hole of the ceramic ferrule the ceramic ferrule will be pressed on the welding surface by ceramic ferrule holder by the force of spring device inside the welding gun. Firstly the drawn arc machine is set up for the appropriate stud diameter.
