- Welding sequence is as with drawn arc stud welding (ARC) with the
exception of higher current and shorter welding time (≤ 100 msec).
- This variant is suitable for stud diameters of up to 12 mm to thin plates.
- As the process up to 8 mm is often used without weld pool protection, studs with upset flange are used. In this way, a higher tensile strength of the weld zone is achieved in the welded area than in the stud shaft in spite of the existence of pores.
- From 8 mm stud diameter upwards, a shielding gas should be used to avoid pore formation.
