Firstly the drawn arc machine is set up for the appropriate stud diameter.

Drawn arc stud welding ceramic ferrule.

The stud is usually joined to a flat plate by using the stud as one of the electrodes the polarity used in stud welding depends on the type of metal being used. 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. Drawn arc stud welding joins a stud and another piece of metal together by heating both parts with an arc. Used for multiple purposes in stud welding.

Ceramic ferrules are required for drawn arc stud welding because the process is a longer weld time than other welds the welding studs are typically thicker in diameter and the weld will be required to hold greater weights than other welding formats. The stud will be inserted into the chuck of the stud welding gun and positioned onto the workpiece possibly by adding a ceramic ferrule. Ceramic ferrules are essential part of the standard shear connectors shear studs drawn arc stud welding process. Drawn arc stud welding.

Weld studs are a permanent solution to fastening metal to metal. Ferrules are disposable items. Third the ferrule forms the molten metal into the fillet. Ceramic ferrules are an essential part of the standard drawn arc stud welding process.

Our welding technology explained in detail. First the ferrule helps to shield the arc from the operator. This ceramic ferrule contains the tip of the welding stud and more effectively distributes heat and shielding gas around the weld point. Welding aluminium for example would usually require direct current electrode positive dcep.

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. To understand why it s important to know how drawn arc stud welding works. The best aluminum studs have a built in ignition tip that burns away before the weld is performed. Second it minimizes the atmosphere that the flux must purge.

Finally the fillet vents allow weld gases to escape. Why are ceramic ferrules essential for stud welding. Initiating the welding process. The process drawn arc stud welding is used for studs of an approximate diameter of 3 to 25 mm welding current up to 3 000 a and welding times up to 3 000 ms.

Drawn arc stud welding with ceramic ferrule. Bolte gmbh home. Without ceramic ferrules the drawn arc process wouldn t be effective and welds wouldn t be as strong.
