DESCRIPTION
EXAMEN CWITRANSCRIPT
A welding procedure is being qualified for the welding of A709 grade 36 plates for cyclically loaded structures. Assuming this structure was for the construction of high way bridge. The welding process is SMAW, and the welding configuration is a single V-groove weld with a steel backing. The thickness of the test plate is 15.9 inches. The plate is welded in the vertical position.
What is the required electrode classification for this qualification?
E70XX
ER70S-X
E6XT-X
a and b
What is the required preheat and interpass temperature for this Procedure?
225 F minimum to 107C maximum
300 F minimum to 150C maximum
150 F minimum to 107C maximum
225 F minimum to 107C minimum
None of the above
For what thickness will this Procedure be qualified if the required tests are successfully passed?
Unlimited

Both a and b
Both b and c
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?
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
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
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
The visual inspection shall be performed not less than 48 hours after completion of the weld, in order to provide time for the quality personnel to leave the area for X-ray personnel
None of the above
