1. General welding information

1.1 Weld seam preparation

General
The surfaces in the vicinity of the weld seam
must be suitable to obtain fault-free weld
seams. Moisture and contamination such
as dirt, rust, scaling, scum, paint, oils and
greases have a negative effect on the result.
If there are weld seam faults that can be
traced back to the aforementioned surface
contamination, the components in the vicinity
of the weld seam must be prepared accor-
dingly (clean, dry, etc.). If welding multiple
layers, before welding the next layer, the
surface must be prepared again to ensure
that the next layer can be welded without
problems.
Weld edge shape
The weld edge shape on metal sheets and
profiles must be established as shown in
EN ISO 9692-1.

Processing procedure
Weld edges should preferably be processed
mechanically. If cutting edges are produced
using autogenous flame cutting, the material
to be cut must correspond to
EN ISO 9013-442. The fusion faces must be
free of oxidation products.
