Ceramic Ferrules For Stud Welding

Without ceramic ferrules the drawn arc process wouldn t be effective and welds wouldn t be as strong.

Ceramic ferrules for stud welding.

Ferrules are disposable items. Used for multiple purposes in stud welding. Third the ferrule forms the molten metal into the fillet. Finally the fillet vents allow weld gases to escape.

The stud will be inserted into the chuck of the stud welding gun and positioned onto the workpiece possibly by adding a ceramic ferrule. Second it minimizes the atmosphere that the flux must purge. 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. Our ceramic ferrules can go from ambient temperature to weld temperature in a split second and resist cracking or exploding.

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. 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. As disposable items they are mass manufactured quickly and inexpensively. Because of this manufacturing method ceramic ferrule tolerances can be greater than machining or.

Firstly the drawn arc machine is set up for the appropriate stud diameter. Why are ceramic ferrules essential for stud welding. Initiating the welding process. First the ferrule helps to shield the arc from the operator.

To understand why it s important to know how drawn arc stud welding works. Ceramic ferrules are essential part of the standard shear connectors shear studs drawn arc stud welding process. Ferrules are cast in a mold out of a low grade moldable ceramic.
