Drawn arc stud welding ceramic ferrule.
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.
Why are ceramic ferrules essential for stud welding.
Welding aluminium for example would usually require direct current electrode positive dcep.
Without ceramic ferrules the drawn arc process wouldn t be effective and welds wouldn t be as strong.
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.
In general the positive pole of the power source is connected to the workpiece.
First the ferrule helps to shield the arc from the operator.
Our welding technology explained in detail.
Drawn arc stud welding with ceramic ferrule.
Drawn arc stud welding joins a stud and another piece of metal together by heating both parts with an arc.
Second it minimizes the atmosphere that the flux must purge.
Used for multiple purposes in stud welding.
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.
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.
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.
This ceramic ferrule contains the tip of the welding stud and more effectively distributes heat and shielding gas around the weld point.
They come in all shapes and sizes and are adaptable to an infinite number of applications.
Another key difference in aluminum welding is the stud design for drawn arc stud welding processes.
Finally the fillet vents allow weld gases to escape.
Third the ferrule forms the molten metal into the fillet.
Ferrules are disposable items.
Drawn arc 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.
The best aluminum studs have a built in ignition tip that burns away before the weld is performed.
Weld studs are a permanent solution to fastening metal to metal.
