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 de-
vice once by 30° 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
30° towards the failing seam.
