Our welding technology explained in detail.
Drawn arc stud welding ceramic ferrule.
First the ferrule helps to shield the arc from the operator.
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.
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.
Ceramic ferrules are an essential part of the standard drawn arc stud welding process.
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.
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.
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.
Ceramic ferrules are essential part of the standard shear connectors shear studs drawn arc stud welding process.
Without ceramic ferrules the drawn arc process wouldn t be effective and welds wouldn t be as strong.
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.
Initiating the welding process.
Drawn arc stud welding with ceramic ferrule.
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.
They come in all shapes and sizes and are adaptable to an infinite number of applications.
Second it minimizes the atmosphere that the flux must purge.
The best aluminum studs have a built in ignition tip that burns away before the weld is performed.
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.
Used for multiple purposes in stud welding.
In general the positive pole of the power source is connected to the workpiece.
Weld studs are a permanent solution to fastening metal to metal.
Ferrules are disposable items.
Drawn arc stud welding joins a stud and another piece of metal together by heating both parts with an arc.
