Re: [MW:33970] Weldability of A283 Gr C with A573 Gr70

There are certain factors to be considered while selecting the welding consumable.

1. The Tensile strength of the welding consumable shall be higher than the minimum specified Tensile strength of the Base material.

2. If two different grades are welded the welding consumable tensile strength shall be higher than the lowest grade.

3. If it is a structural weld and welding to the pressure boundary then low H2 electrode is preferred such as E7018 / E7108-1.

4. If it is between a non pressure part to non-pressure part then  you can prefer E6013 for your requirement and thickness.

5. If the Thickness(>25mm) & Carbon equivalent is higher it is preferred to weld with a low H2 electrode such as E7018

Thanks & Regards

But sir we use these two nuances for construction of storage tanks. Is it applicable ? with different thickness 

sir please could you give me more arguments about the weldability of these two nuances ? 

thank you a lot for your helps sir

Dear friend 

could anyone answer my question, the question is : could we weld A573 GR70 with A283GR C

In my opinion we can't  weld them because the minimum specified  tensile are 

for A283 GR C = 380 MPA

for A573 Gr70 = 485 MPA

Please friend help me i need this information emergency

if the answer is yes which type of filler metal we should use for SMAW
