5.7 Welding
parameters
NOTE
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 also influence the welding parameters (e.g. if the lift is increased, usually the
charging voltage must be increased too).
Random samples should be taken during any production process to ensure consistently good welding
results (see DVS guideline, Part 1, "Quality assurance of stud welding joints").
The welding parameters were determined with the BMS-10P stud welder and the PS-3 stud welding
gun using a lift adjustment of about 2.5 mm. A steel plate with a thickness of 2 mm served as base
metal for welding copper-plated CD studs (4.8) as per DIN EN ISO 13918.
Charging voltage table (in volt) BMS-10P
The charging voltage is preset according to the table. It can be adapted via the function keys
depending on the respective welding task.
NOTE
Depending on the charging capacity of the battery (Battery 1 = 33,000 µF | Battery 2 =
99,000 µF), different values for the charging voltage are specified.
