2016 Book of Specifications (41 questions)

This is training with a total of 427 sample questions included.

 
How would I get the answer to the following:
A welder has been qualified for groove welding using a 12 in. schedule 80 pipe test coupon in the 2G position.
Is the welder qualified for the welding of 4 in. schedule 80 pipe?
Part B  Book of Specifications  - APPENDIX XI Page 13 – Table 2 (test on pipe & tubing):

Answer is yes but not in the 5G or 6G position

You have to select the most correct answer

This table diameter limits 4” and smaller  and 4” and larger.

Since 12” is larger than 4” (even if it is not listed on the chart) welder will be qualified for 4” and larger – 12” is included in the 4” and larger group.  The welder was tested in the 2G position (horizontal weld test – qualifies the welder for F (Flat) and H (Horizontal) Part B  Book of Specifications  -  APPENDIX XI (continued) Page 14, Welder Qualification – Type and Position Limitations Answer is yes but not in the 5G or 6G position

I doubt you have a question concerning this, however K = Kelvin:
1 degree Fahrenheit  =   255.9278  degrees Kelvin
1 degree Kelvin =   -457.866  degrees Fahrenheit  
1 degree Celsius  =   274.15 degrees Kelvin
1 degree Kelvin =   -272.15 degrees Celsius

GMAW / FCAW

Joint Designation B-U2-GF  (Note - this question is referring to the image above)

The specified range of  root  face ( f  = minimum of 0 to a maximum of 1/8 ) for the initial groove preparation is 0 to 1/8 in., what is the range of root face permitted As Detailed (+ 1/6,  - 0 ) for this joint?

 

a.  0  to 3/16 in.

b.  1/16 in. to 3/16 in.

c.  1/16 in. to 1/8 in.

d.  1/8 in. to 3/16 in.

You would add the specified ( f = minimum 0 to maximum 1/8 ) to the As Detailed tolerance (+ 1/6,  - 0 ).

Minimum   0 – 0  = 0

Maximum  1/8 +  1/16 = 3/16

This will give you  ( a. )  as the correct answer = 0 to 3/16

-------------------------------------------------------------------------------------------------------------------------------------------------


GMAW / FCAW

Joint Designation B-U2a-GF  (Note* this question is referring to the image above)

The specified Groove Angle ( a ) for Root Opening ( R ) 3/16 for the initial groove preparation is,   a  = 30 degrees, what is the range of Groove Angle permitted As Fit Up (+ 10 degrees,  - 5 degrees ) for this joint?

 

a.  25  to 40 degrees

b.  1/16 in. to 3/16 in.

c.  1/16 in. to 1/8 in.

d.  1/8 in. to 3/16 in.

You would add the specified ( a = 30 degrees ) to the As Fit Up tolerance (+ 10,  - 5 ).

Minimum   30 degrees  – 5 degrees  = 25 degrees

Maximum  30 degrees +  10 degrees  = 40 degrees

This will give you  ( a. )  as the correct answer = 25 to 40 degrees

 

GMAW / FCAW

Joint Designation B-U2a-GF  (Note* this question is referring to the image above)

What is the specified Root Opening for Prequalified joint B-U2a-GF using the gas shielded FCAW process.

 

a.  1/4 in.

b.  3/8 in.

c.  3/16 in.

d.  not specified

 

The only gas shielded FCAW listed has a root opening specified as 3/16.  You would not add the specified ( 3/16 ) to the As Detailed or  the As Fit Up since the question only ask what the specified Root opening is.

This will give you  ( c. )  as the correct answer =  3/16 in.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------


(Note*  the information below is referring to the image above)
 Are confusing the Tolerances with a Range.  The tolerances are not showing a Range.  Tolerances show what can be added to the root opening, and what can be  subtracted from the Root Opening
 
 To help you understand, let’s start off with understanding in the Tolerances the  – 0   is equal to subtracting nothing or no change to the Root Opening.  
 
Now let’s look at just the Root Opening dimension.  Note – it is a Range  0  to 1/8 =  (Root Opening Closed up which is reflected by 0 to a gap of 1/8)
 
On the other hand the Tolerance - As Detailed -  is not a range – it is simply adding 1/16  
Add this to the original root opening and now you have a Root Opening Closed up to a gap of now 3/16
 
Root Opening = 0  to 1/8   if we were add the Tolerances As Fitup (+ 1/16, - 1/8) you could add 1/16 to the Root Opening.

This would make the Root Opening 0 to 3/16,  then you could take away 1/8  (-1/8) from the Root Opening which would make the Root Opening 0.

So the As Fitup would be 0 to 3/16
