CSWIP 3.1 (WELDING INSPECTOR) MULTIPLE CHOICE QUESTIONS
1. When manual metal arc welding is being carried out on an open construction site, which
group of welders are the most likely to require continuous monitoring?
(a) Concrete shuttering welding teams
(b) Pipe welding team
(c) Plater welders
(d) Plant maintenance welders
2. You notice manual metal arc electrodes, stripped of flux, are being used as filler wire for
TIG welding. You would object because:
(a) It is too expensive
(b) The wire would be too thick
(c) The weld metal composition may be wrong
(d) The wire is too short
3. When open site working, serious porosity in metal arc welds is brought to your attention.
What would you investigate:
(a) Electrode type
(b) Power plant type
(c) Electrode storage (d) Day temperature
4. When “H2 control” is specified for a manual metal arc welding project, the electrode would
normally be:
(a) Cellulose
(b) Iron oxide
(c) Acid
(d) Basic
5. You would with certainty recognize a hydrogen controlled flux covered electrode from its:
(a) Colour
(b) Length
(c) Trade Name
(d) AWS / BS639 Code Letter
,6. The steel composition in a structural contract is changed form 0.15% carbon, 0.6%
manganese to 0.2% carbon, 1.2% manganese. Might this influence the incidence of:
(a) Porosity
(b) Cracking in the weld area
(c) Undercut for fillet welds
(d) Lack of root fusion defects
7. One of the following alloys is non-magnetic. Which?
,Page 1 of 45
, (a) 4% Chromium Molybdenum
(b) 12% Chromium
(c) Austenitic Stainless Steel
(d) 9% Nickle Steel
8.
When TIG welding Austenitic Stainless Steel pipe, Argon gas baking is called for. This is to:
(a) Prevent oxidation
(b) Prevent under bead cracking
(c) Prevent porosity
(d) Control the penetration bead shape
9.
Pre-heating a carbon steel manual metal arc welding is carried out to minimize the risk of:
(a) Scattered porosity
(b) Worm hole porosity
(c) Parent metal cracking
(d) Lack of penetration
10. In UK practice, BS499 part 2 specifies that the drawing dimension quoted for a fillet weld is
the:
(a) Leg length
(b) Actual throat thickness
(c) Weld length
11. For open site manual metal arc welding the following equipment is available. Which would
you choose for safe working?
(a) Single operator transformer
(b) Multi operator transformer
(c) AC / DC composite power unit
(d) Diesel engine driven motor generator
12. If Submerged arc welding is to be used to make butt welds, which would you be most critical
of?
(a) The root gap tolerance
(b) The angle of preparation
(c) The root face width
(d) The gas cut finish
