Drawn arc stud welding technology with ceramic ferrules
In drawn arc stud welding with ceramic ferrules, the ceramic ferrule serves as weld pool
protection and fulfils the following functions:

It centres the electric arc.

It protects the welding point from the atmosphere.

It ensures the formation of a welding bead.

It prevents too rapid cooling of the welding pool.

It partially protects against spraying sparks.
To ensure the formation of a welding bead, each stud requires a ceramic ferrule
matching its diameter and shape. After each welding process, the ceramic ferrule must
be knocked off and replaced by a new one. Generally this method allows you to weld in
any position.
Functional principle
The stud touches the
workpiece. The stud is lifted from the
workpiece. The arc is
ignited. The stud immerses in the
welding pool. The material
solidifies and the stud is
solidly welded.
IMPORTANT
Protect ceramic ferrules from moisture and humidity.
