Re: [MW:25436] Re: Using of ER70S-6 in place of ER70S-2

Ti and Al are added to act as additional deoxidizers to cleanse the weld of impurities. In the case of MAG welding, additional Ti and Al into the standard ER70S-6 isn't mandated. In case you need them in the weld pool, consider changing the transfer mode to spray or rotating arc or pulsed mode. Some of these will require change of gas to a Argon based mixture

Many thanks!

in ER70S6 we have added Ti- 0.011% and Al - 0.012%. We are facing spattering issue in MAG-CO2 .

Is Ti and Al reason for spattering?

You have not mentioned the welding process in use at your end

If it is TIG, flat no. as 70 S2 contains triple deoxidisers Al, ZN & Ti and used with argon gas.

ER 70S06 does not have them and will not give x-ray quality welds.

If it is MAG/CO2 process or with argon gas, you can go ahead. 

Ti addition alone with 70 S6 do not help. S6 also contains excessive Mn & Si and not used for 

TIG process.

Please guide- If we add Ti in ER70S-6 in range of 0.011%, what will be the effect during CO2 welding?

Dear Expert,

Please guide whether ER70S-6 can be used in place of ER70S-2. Please give code reference.
