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.
‹ 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.
92-40-135A).
