When welding high-manganese steels, which one of the following must
be avoided?
Inhalation of welding fumes.
The mechanical test used to determine the ability of a material to resist
failure by brittle fracture
requires the use of:
C) An impact test specimen
2 multiple choice options
When the ultrasonic transducer or probe is in direct contact with the
material under test the ultrasonic method is:
Can be any of these methods, the shear wave method, the longitudinal
wave method, the transverse wave method or the angle beam technique
,State one reason for measuring dimensions from a single reference line
or datum
To avoid cumulative errors
According to CSA W59 what is the minimum distance from the weld at
which to measure the preheat in plates 44mm thick?
a) 75mm
2 multiple choice options
A 'pipe' is a solidification cavity in steel. Where would you most likely
find such a defect when inspecting a rolled plate?
b) in the middle of an end section
2 multiple choice options
For two 38mm thick plates to be groove welded without a backing bar
what is the maximum misalignment permitted by CSA W59?
3mm
,Is the size of a fillet weld always the same as the measured leg length?
No, The size is smaller than the measured leg length for a concave fillet
What dimension is measured to determine the size of a concave fillet
weld?
The Throat
When using a string as a reference line when measuring distortion in a
flat plate the measurement should be made horizontally on to a vertical
plate.
a) Because it avoids error due to sag in the string
2 multiple choice options
Which is not a recommended method for surface cleaning of a part for
liquid penetrant examination?
, b) Blasting with shot or dull sand.
2 multiple choice options
Which of the following weld defects is most likely to be missed by
radiography in a weld:
C) Cracking.
2 multiple choice options
In the choices given below, metallographic tests would be the least
informative with regard to the:
c) Ability of the material to withstand repeated fluctuating loads.
2 multiple choice options
In producing a drawing for a scale of 1:50, what would be the distance
represented by a distance on
the drawing of 6 cm?
300 cm
