Re: [MW:25430] Re: Using of ER70S-6 in place of ER70S-2

what Sridhar said is as per code recommendation. Triple deoxidiser is used to deoxidise any thing in the parent metal ,not in the fully arc stream. If we use ER70S6 as TIG rod, we have to be carefull in adjusting Mn and Si content in the wire, otherwise hardness of weldmetal will increase.

What are you saying doesn't make sense at all

Why you need deoxidizing agents in a process with inert shielding?

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?

Sanjeev

Dear Expert,

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