DESCRIPTION

EXAMEN CWI

TRANSCRIPT

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

1/8 to 2T inches

1/8 to 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

If the welder who performs this procedure qualification test is also qualified, in what position that individual qualified for production welding?

F,OH groove in plate

F,H,OH fillet in plate

F fillet in pipe

None of the above

All of the above

What test specimens are required for this qualification test?

2 reduced section tensiles, 2root bends, 2 face bends

2 reduced section tensiles, 4 side bends

2 reduced section tensiles, 2root bends, 2 face bends, 2 macro etch specimens

2 reduced section tensiles, 2root bends, 2 face bends, 4 side bends

1 and 4

4 only

1 only

In the welding procedure qualification above, what is the required and acceptable NDT method to be used to verify the soundness of the weld?

VT

UT only

RT only

RT or UT

None of the above

If this same welding procedure is qualified on 16 inches schedule 160 pipe, for what range of diameters and wall thicknesses is this procedure considered qualified?

Diameter 16 and over; wall thickness from 3/8 to unlimited

Diameter 16 and over; wall thickness over 3/8

Diameter 16 and over; wall thickness unlimited

Diameter 16 and over; wall thickness from 1/8 to 1/2

None of the above

The Senior Welding Engineer of PEAM integrated welding academy limited has specified a welding procedure specification for her new structural project. The procedure is being qualified for the welding of ASTM A36 steel plate. This procedure was used to qualified individual welder, using SMAW process. The welding engineer also specified B-U2 single V-groove weld configuration with a steel backing, 1/8 root opening, 1/8 root face, 60 degree groove angle. Assuming each individual welder was tested on 25.4mm thickness test plate at 3G position.
