Ceramic Ferrules For Stud Welding

To understand why it s important to know how drawn arc stud welding works.

Ceramic ferrules for stud welding.

Why are ceramic ferrules essential for stud welding. 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. Because of this manufacturing method ceramic ferrule tolerances can be greater than machining or. 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.

Used for multiple purposes in stud welding. Initiating the welding process. Ceramic ferrules for arc stud welding are disposable items. Firstly the drawn arc machine is set up for the appropriate stud diameter.

Our ceramic ferrules can go from ambient temperature to weld temperature in a split second and resist cracking or exploding. After cooling the ferrule is broken off to reveal the weld. 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. The stud will be inserted into the chuck of the stud welding gun and positioned onto the workpiece possibly by adding a ceramic ferrule.

Ferrules are disposable items. First the ferrule helps to shield the arc from the operator. Ceramic ferrules are essential part of the standard shear connectors shear studs drawn arc stud welding process. Without ceramic ferrules the drawn arc process wouldn t be effective and welds wouldn t be as strong.

Ferrules are cast in a mold out of a low grade moldable ceramic. Finally the fillet vents allow weld gases to escape. They are taken out of the mold and are dried.
