RE: [MW:19745] DIFFERENCE BETWEEN ER70S-2 &ER70S-6

Dear Sir,

Both of them are using in GTAW and GMAW

The mechanical properties of 6 is better than 2 and also you can use active gas and depend on using gas 100% CO2 till 75%Ar+25 %CO2 you can see reducing the porosity and spatter.

For more information about that you can check in ASME SEC II

we have used both 90%Ar + 10% Co2 and 95%+5%, we found that spatter level has come down very considerably( Sticking to job is almost nil )

Dear Sir,

Thanks for your reply but when I check Radiography films and Observed lots of cluster porosity and side L/F

Dear Maulik Thakkar

IF WE USE IN ER70S-6 ARGON+CO2 (85%+15%). THEN WHAT HAPPEN..........

ER70S-2 is compatible GTAW wire to be use with Ar gas only. Where as -6 is compatible GMAW wire generally use with CO2 GAS. Si n Mn has to add as deoxifizers to eliminate effect of O2 from weld pool.

Dear Members,

I would like to know difference between ER70S2 &ER70S6?

What does "2" and "6" mean in them and which welding process we use them?

Thankyou!
