Re: [MW:8803] Difference between E-7016 & E-7018

Dear Sil,

Both are Basic type, low hydrogen rods and having similar strength, but E7016 is without the iron powder in flux.

E7016 :Low hydrogen potassium Electrode ( not BASIC SODIUM LOW HYDROGEN; E7015 is Low hydrogen sodium electrode)

E7016's have less slag than E7018's so are better for root-run, positional welding (better controlled positionally) than E7018, easy deslagging and baking/redry not required

 

E7018 :Low hydrogen potassium, iron powder Electrode

E7018 has iron powder added to the flux, which goes into the weld-pool when the rod is burned, so more metal is deposited. Baking/redry required.

 

Both electrodes having F no. 4. You can use E7018 instead of E7016, here essential variable (F no.) not changed, but re-write your WPS accordingly.

M.Shankar

Dear sir,

What is the quality wise difference between E-7018 ( BASIC LOW HYDROGEN) & E-7016 ( BASIC SODIUM LOW HYDROGEN).Can i use E-7018 insted of E-7016.

Where is the specific area of these two electrode

regards

sil
