The weld time as per drawn-arc method is approx. 100ms - 1000ms.
For the short-cycle method the weld time is approx. 10ms - 100ms.
1.5 Welding Elements
According to the short-cycle method threaded studs (SC-B; SC-Z), in- ternal inserts
(SC-1) and pin studs (SC-S) of various dimensions and materials can be welded.
In keeping with the drawn-arc method threaded studs, head studs and cylinder pins
and other welding elements (according to EN ISO 13918) can be welded.
The following conditions must be observed:
•
The weld gun has been set to the studs to be welded in the fac- tory
•
The stud type is noted on the type plate of the gun
•
The studs to be welded are specified in chapter 6.3.7
1.6 Ceramic Ferrules
Ceramic ferrules (according to EN ISO 13918) are used when welding in keeping
with the drawn-arc method. They form a combustion chamber around the weld,
which centers the arc and protects the user against welding spatter.
In addition to this, the cooling down rate of the weld is reduced and an even shape of
the bead is achieved.
The following conditions have to be observed:
•
An appropriate ceramic ferrule is required for every stud diameter
•
For differing ceramic ferrules corresponding ceramic ferrule holders are needed
