Working principle : At a certain current, voltage parameters, welding studs are held by welding torch, do lifting movement with excitation arc.Arcing intension and time are coordinated by welding power. Then welding pool is formed, solidified and completed.Drawn arc stud welding with ceramic ferrule is recommended for studs with diameter of more than 12 mm. If it is required to protect the weld pool from atmosphere, shielding gas should be used. This process variant is also used with automated applications.

Operation steps

1. Welding process with ceramic ferrule: Joining of stud-type welding elements with a diameter 2 to 25 mm (M24) onto a thick metal sheet, mild steel or stainless steel.
2. The welding stud is lifted and a secondary arc (pilot arc) of low current is ignited between stud tip and work piece.
3. Then (he ignition of the main arc is carried out. Stud and work piece are melted, The stud is moved to the work piece, the two molten zones join.
4. The molten areas solidify. The short and dean welding process does not require any machining.
5. As a result, an even joint is achieved with a strength which is above the strength of stud and base material.
