The dimensions of the test piece must be sufficient to carry out all tests. The thickness of the test
piece must be the same as used in later production. Use the same welding positions and edge
distances as on the component to be welded later. If it is possible and sensible from an economical
point of view, use parts that are identical to those used in later production.
Comply with the minimum sheet thickness as per DIN EN ISO 14 555.
