reference to our WPS we used (Ador electrodes) e 8010 for root and
8018 for hot fill pass.
We took NDT and its okay. But after 1 month 4 weld joints crack. We
checked the macro hardness for existing and cracked joint . There was
a high hardness eg 351, 329 on root and in weld metal cap side 280
above. Which is very high.
Can you please tell me for this material what type of electrodes to be
used? And why this occoured ?? And what may be possible reason for
this occourance?
