Ceramic Ferrules For Stud Welding

Second it minimizes the atmosphere that the flux must purge.

Ceramic ferrules for stud welding.

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. 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.

Used for multiple purposes in stud welding. As disposable items they are mass manufactured quickly and inexpensively. Our ceramic ferrules can go from ambient temperature to weld temperature in a split second and resist cracking or exploding. Finally the fillet vents allow weld gases to escape.

After cooling the ferrule is broken off to reveal the weld. Ceramic ferrules for arc stud welding are disposable items. Firstly the drawn arc machine is set up for the appropriate stud diameter. To understand why it s important to know how drawn arc stud welding works.

Initiating the welding process. 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. Ferrules are cast in a mold out of a low grade moldable ceramic. First the ferrule helps to shield the arc from the operator.

Why are ceramic ferrules essential for stud welding. Ferrules are disposable items. Third the ferrule forms the molten metal into the fillet.
