EN 15614-1 Charpy Impact Test for Multiple Process

[cnkn]

In EN 15614-1, the last paragraph of the item 7.4.5 says "Where multiple welding processes are qualified in a single test piece,impact test specimens shall be taken from the weld metal and HAZ that include each process"

Lets take a test piece with a thickness of 20mm welded with GTAW(3mm)+GMAW(17mm).Do I have to use sub-size specimen (2,5x10x55) for GTAW and standard test specimen (10x10x55) for GMAW? I mean, should only one process be present on each specimen?

No, you can draw single sample which includes each process.you can include sketch of drawn sample in report to show each process weld/HAZ is included.
