|
| 1) |
This is applied more various among the two welding processes. |
| Heat needed for welding is generated by DC-Arc between Stud and material, Welding current is gained by Main Transformer, And weding time and combination of welded stud and material is controlled for application. |
| |
| 2) |
Principle of Operations |
|
① Power supplies to Solenold Coils inside Welding Gun
② Stud gets off material and arc cause
③ Stud base and material become welding by the arc
④ When ending controlled Welding time, welding current is cut off, as well as
power supply into solenold Colls.
⑤ Stud joins with welded portion of material by Main spring of Welding Gun. |

| 3) |
Drawn Arc Process(DA Type) |
|
Once positioning for welding work with inserting stud into Chuck of Welding Gun, required Ferrule, is used for this method, which is adopted stud specification. |
 |
|
|
| 4) |
Short Cycle Process(SC Type) |
|
This method is simllar to DA Type but it is applied for Car Body Panel of Motcrcycle industry as its welding time is used very shortly(1~100ms) |
 |
| |
|
|
 |
|
| 1) |
CD Type of stud welding is a welding process that saves electrical energy in a condenser and generates arc geat, at the same time joins with welded portion by spring pressure of Welding Gun. |
| 2) |
Arc heat is generated by Vaporization of Stud Base Tip caused by a very short-resistant heat |
| 3) |
In CD Type, contact Mode and Gap Mode are used. Welding time in contact Mode is required within 3~6ms, the one in Gap Mode is required within 6~15ms. |
| 4) |
Charge capacity, Charge voltage Spring pressure, etc are inevitable for CD Type of Stud Wedling. |
