13 Checking the Quality of the Weld
13.2 Carrying out Bending Test
You can purchase from HBS a bending device with inserts for various diameters of
the welding elements.
The bending test serves as an easy work sample and as a check for the selected
welding parameters. The welded joint is stressed by bending in a non-defined way.
1 - Welding element
2 - Welded joint
Place the bending device on the
welding ele-
ment (1)
and
bend the
welding element (1)
with the bending
device once by 60° in any direction.
The bending test is passed if a crack or a fracture of
the welded zone does not occur.
Further tests should be conducted if the connection fails in the weld
area.
In this case,
bend
the welding element exactly in the opposite direction
by 60° towards the failing seam.
For a
non-destructive strength test
of the welding elements HBS offers a
torque bending test device
in accordance with DIN EN ISO 14555 (Order No.
92-40-125A).
