Re: [MW:25410] Re: Using of ER70S-6 in place of ER70S-2

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?
