Welding parameters for welding operation

IMPORTANT
The set welding parameters influence the reproducibility and quality of the welding
results to a large extent. The parameters depend on the size of the studs and the
material properties. The values indicated in the tables are standard values which are
exclusively valid for studs supplied by SOYER. They may vary depending on the type
of workpiece, the workpiece thickness, the surface condition of the workpiece and on
environmental conditions (e.g. low outdoor temperatures). The settings of the welding
gun or welding head influence the welding parameters as well.
Random samples should be taken during any production process to ensure constantly
good welding results (see DIN EN ISO 14 555, "Arc welding of metallic materials")
The welding parameters were determined with the BMK-12 W stud welder and the
PH-3N stud welding gun having a lift setting of about 2.5 mm.
A steel plate with a thickness of 5 mm was used as base material for welding SOYER
welding studs as per DIN EN ISO 13 918.

When using stud diameters exceeding 6 mm, we recommend the application of
shielding gas or ceramic ferrules in order to prevent pore formation and to optimise
bulging.

Minimum sheet thickness when welding with drawn arc operation

Observance of the minimum sheet thickness prevents the plate from being burnt
through during the welding process.
