Die Kondensatoren werden an einer voreingestellten Spannung gelanden, dem zu verschweißenden Durchmesser entsprechend. Der Bolzenzapfen wird mit dem Blech in Kontakt gebracht. |
The capacitors are charged to a pre-set voltage to suit the diameter to be welded. The stud pip is placed into contact with the sheet. | I condensatori sono caricati ad una tensione pre -impostata in funzione del diametro da saldare . Il codolo del perno viene posto a contatto con la lamiera. | |
|
Nach dem Auslösen wird die gespeicherte Energie als Hochstromimpuls entlassen, womit der Zapfen geschmolzen wird und sich ein Bogen bildet. |
Upon triggering, the stored energy is discharged as a high current pulse, melting the pip and producing an arc. | Dopo l''in nesco , l''energia accumulata viene scaricata come un elevato impulso di corrente , sciogliendo il codolo e producendo un arco . | |
|
Die auf dem Bolzen ausgeübte Kraft verursacht teilweise die Schmiedung des Bundes mit der geschmolzenen Oberfläche des Bleches, womit sich eine komplette Fusion ergibt. |
Return spring pressure forges the stud into the molten surface area on the sheet to give complete fusion across the flange. | La pressione esercitata sul perno causa la fusione parziale della flangia con la superficie fusa della lamiera e ne completa l''unione. | |

Der Strom und die Schweißzeit sind dem zu verschweißenden Durchmesser entsprechend voreingestellt. Der Bolzen wird dann auf die Platte gesetzt. |
Current and weld time is pre-set to suit the diameter to be welded. The stud is then placed on the plate | La corrente ed il tempo di saldatura sono pre- impostati in funzione del diametro da saldare . Il perno viene poi collocata sulla piastra | |
|
Durch die Auslösung wird ein Pilotbogen verursacht und der Bolzen erhebt sich zur festegesetzten Höhe. |
Upon triggering, a pilot arc occurs as the stud lifts to a pre-set height. | Dopo l''innesco, si verifica un arco pilota ed il perno si solleva ad un''altezza prefissata . | |
|
Der Hauptbogen schmilzt die Schweißspitze des Bolzens und verursacht ein Schmelzbad in der Platte.
|
The main arc then melts the weld end of the stud and creates a molten pool in the plate |

principale
scioglie
la punta a saldare del perno

|
Die auf dem Bolzen ausgeübte Federkraft verursacht das Schmelzen der Spitze in das Schmelzbad. Die Hülse enthält das geschmolzene Metall und formt daraus das Gewinde. |
Return spring pressure forges the stud into the molten pool. The ferrule contains the molten metal and shapes the fillet | La pressione a molla esercitata sul perno crea la fusione della punta nel bagno di fusione . La ferrula contiene il metallo fuso e ne modella il filetto. | |
