Question Answer
The subcontractor has got only EN 3834-2 certificate. The manufacturer is responsible for the whole product, the subcontractor is responsible for the welding technology.
Is EN 3834-2 enough for manufacturing according to EN 1090-1?
This is not enough.The subcontractor has to be certified acc. to EN 1090-1 by a Notified Body for the suitable execution class.
