Questions Paper 1 - MSR-WI-1a
Name: ……………………………….…………………………. Date: ……………………
1 Which mechanical test can be used to measure the toughness of weld metal, HAZ and
parent material?
a Macro.
b Nick break.
c Hardness.
d Charpy impact.
2 Which is the best destructive test for showing lack of sidewall fusion in a 25mm
thickness butt weld?
a Nick break.
b Side bend.
c Charpy impact.
d Face bend test.
3 The principal purpose of a welder qualification test is to: a
b Assess the weldability of the materials.
c Test
Decidethewhich
skill of
NDTthemethods
welder. to use.
d Give the welder practice before doing production welding.
4 A fabrication procedure calls for the toes of all welds to be blended in by grinding. The
reason for doing this is to:
a Make the welds suitable for liquid (dye) penetrant inspection.
b Improve the fatigue life.
c Reduce residual stresses.
d Improve the general appearance of the welds.
5 For full penetration single-sided butt joints, root bead penetration and profile are
mainly influenced by:
a Root face.
b Bevel angle.
c Root gap.
d Included angle.
6 Which of the following would be cause for rejection by most fabrication standards
when inspecting fillet welds with undercut, a small amount of?
a Depth.
b Length.
c Width.
d Sharpness.
, 7 When visually inspecting the root bead of a single V-butt weld it should be checked for:
a Lack of root penetration.
b HAZ hardness.
c Tungsten inclusions.
d Slag.
8 The strength of a fillet weld is determined by:
a Leg length.
b Weld profile.
c Weld width.
d Throat thickness.
9 The European Standard for NDE of fusion welds by visual examination is:
a EN 15614.
b EN 2560.
c EN 287.
d EN 17637.
10 Visual inspection of a fabricated item for a high integrity application should cover
inspection activities:
a Before, during and after welding.
b Before welding only.
c After welding only.
d During and after welding only.
11 Incomplete root penetration in a single V butt joint may be caused by:
a Excessive root face.
b Excessive root gap.
c The current setting being too low. d
Both a and c.
12 Incomplete root fusion in a single V butt weld may be caused by:
a Linear misalignment.
b Root gap being too large.
c Root faces being too small.
d Welding current too high.
13 When visually inspecting the face of a finished weld which of the following flaws
would be considered the most serious:
a Excess weld metal height.
b Start porosity.
c Spatter.
d Arc strikes.
