1.4 Material combinations
The material combinations listed in the table below have already been tested. The
weld angle for the material combinations is defined as follows:
a = suitable for any application, such as force transfer,
b = suitable with limitations for force transfer,
c = suitable with limitations only for heat transfer,
– = cannot be welded.
Explanation of superscript numbers:
1)
