Dear Experts,

Greetings!!

Anyone knows the reason for very low impact test values on the weld centerline.

Thanks in advance.

- try to use mixed gas ( argon , CO2 ) instead of pure co2

- reduce as much the layers thickness 

what was the max. hardness value for in the root pass  and in the cap ?
