Drawn arc stud welding technology with shielding gas
For drawn arc stud welding with shielding gas, a gas mixture is used as an aid.
The following shielding gas mixtures are recommended:
82% argon and 18% CO
2
(preferred)
90% argon and 10% CO
2
85% argon and 15% CO
2
This shielding gas shields the weld point from the atmosphere and takes over the weld
pool backing at the same time. Moreover, it ensures a concave fillet weld bead formation
with a blank metallic surface, which reduces the risk of corrosion and achieves better
dynamic characteristics of the weld joint.
When welding with shielding gas without any further aids, the formation of an exact bead
in an accurately calibrated and reproducible version is not possible. Stud welding with
shielding gas can be carried out at considerably shorter distances as there is no need
to install and remove the ceramic rings for each welding process.
