1)
to be checked by test weldings
2)
When using alloyed steels, the welding energy (welding current or welding time) must be reduced by about
10 %.
3)
Information and recommendations on this can be found in DIN EN ISO 14555 .
4)
Information and recommendations on this can be found in DVS 0902 .
6)
Shielding gas according to DIN EN ISO 14175-M21, see chapter 9 “Welding Process”
7)
We recommend the “drawn arc stud welding with ceramic ferrule” welding procedure.
