12.2 Notes on checking the quality of the weld

If the SOYER® stud welding equipment is handled correctly and the correct materials
are selected, the strength of the welding joint (welding zone) is always higher than the
strength of the stud or the base material.
In practice, the following production control tests have proved successful:

12.2.1 Visual inspection

The visual inspection serves as a rough check for major defects. The uniformity of the
weld is assessed. The following table serves as an aid for the assessment of the
welding result:

Press the gun onto the workpiece at an angle of 90°.
When using a contact gun, press it firmly against the spring force.
Press the release button of the gun.
Welding is carried out.
During the welding process, hold the gun steadily and only remove
it vertically from the welded stud after the welding process is
finished. By doing so, widening or damaging the stud chuck is
avoided.
