Drawn Arc Stud Welding Ceramic Ferrule

Drawn arc stud welding joins a stud and another piece of metal together by heating both parts with an arc.

Drawn arc stud welding ceramic ferrule.

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

Our welding technology explained in detail. 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. Weld studs are a permanent solution to fastening metal to metal. Used for multiple purposes in stud welding.

Welding aluminium for example would usually require direct current electrode positive dcep. This ceramic ferrule contains the tip of the welding stud and more effectively distributes heat and shielding gas around the weld point. Why are ceramic ferrules essential for stud welding. Finally the fillet vents allow weld gases to escape.

Ceramic ferrules are an essential part of the standard drawn arc stud welding process. Firstly the drawn arc machine is set up for the appropriate stud diameter. Second it minimizes the atmosphere that the flux must purge. 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 with 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. First the ferrule helps to shield the arc from the operator. Another key difference in aluminum welding is the stud design for drawn arc stud welding processes.

Bolte gmbh home. Third the ferrule forms the molten metal into the fillet. The stud will be inserted into the chuck of the stud welding gun and positioned onto the workpiece possibly by adding a ceramic ferrule. In general the positive pole of the power source is connected to the workpiece.

Drawn arc stud welding. They come in all shapes and sizes and are adaptable to an infinite number of applications. Initiating the welding process.
