Ceramic Ferrules For Stud Welding

Ceramic ferrules for arc stud welding are disposable items.

Ceramic ferrules for stud welding.

The stud will be inserted into the chuck of the stud welding gun and positioned onto the workpiece possibly by adding a ceramic ferrule. As disposable items they are mass manufactured quickly and inexpensively. Why are ceramic ferrules essential for stud welding. 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.

Because of this manufacturing method ceramic ferrule tolerances can be greater than machining or. Ferrules are disposable items. Initiating the welding process. After cooling the ferrule is broken off to reveal the weld.

Ferrules are cast in a mold out of a low grade moldable ceramic. Second it minimizes the atmosphere that the flux must purge. Used for multiple purposes in 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.

Firstly the drawn arc machine is set up for the appropriate stud diameter. Without ceramic ferrules the drawn arc process wouldn t be effective and welds wouldn t be as strong. They are taken out of the mold and are dried. First the ferrule helps to shield the arc from the operator.

Finally the fillet vents allow weld gases to escape. Our ceramic ferrules can go from ambient temperature to weld temperature in a split second and resist cracking or exploding. Third the ferrule forms the molten metal into the fillet.
