No no. Not specimen. The problem with the word "Träger" is, that it denotes
an I-beam ("Doppel-T Träger") or some carrier ("Flugzeugträger"). So it can
be something from simple to a complex structure, as long as it has to carry
some load.
[For confusion:
Under the microscope, the specimen is put onto a "Träger"]
I'm assuming that it either refers to a groove made as a weld
preparation (as opposed to no preparation),
Yes.
Could it refer to a three-point
testing machine, in which a simply-supported beam is loaded in the
middle? Or doesn't that make any sense?
No. Because "Nut" is something smallish. Certainly not big enough to bend an
I-beam into. :-)
It's a text by Otto Graf, published in 1943, about the strength and
testing of welded structures.
Ah! That explains why I couldn't google the word. A lost procedure. And I
have no old books about welding.
