Most important is what kind of classification / certification is required for the wire and are the by manufacturer specified properties for the wire meeting your project requirements. If during WPQR qualification the requirements also comply with the requirements there is no need to investigate the chemical composition any further as long as the wire is an ER70S-6 wire on the certificate!

Hello,--I need help regarding the ER70S-6 mig welding wire. I am currently comparing mill certs from different vendors and not sure which one is the best in terms of quality. Is there anything in particular I should be looking for?Any help would be greatly appreciated!On Tuesday, September 20, 2016 at 6:50:21 AM UTC-5, Diganta Sarma wrote: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!
Sent from my iPhonein 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?

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 forTIG process.

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