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
