4) Assuming ASTM A514 and A517 was qualified replacing A709 grade 36 steel. What shall be the required visual inspection criteria to be performed on the completed weld?

a. The visual inspection shall be performed not less than 48 hours after completion of the weld, in order to check for the susceptibility of these steels to underbead (delayed) cracking

b. The visual inspection shall be performed not less than 48 hours after completion of the weld, in order to permit any weld porosity present at the time of welding to clear up

c. The visual inspection shall be performed in less than 48 hours after completion of the weld, because during these period the weld is said to be solidified
