CSWIP 3.1 model Questions and answers. Paper 1.

3 The principal purpose of a welder qualification test is to: a Test the skill of the welder. b Assess the weldability of the materials. c Decide which NDT methods 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. 14 A burn-through may occur if the: a Current is too low. b Root face is too large. c Root gap is too large. d Arc voltage is too high. 15 A Code of Practice is a: a Standard of workmanship quality only. b Set of rules for manufacturing a specific product. c Specification for the finished product. d Code for the qualification of welding procedures and welders qualifications. 16 A solid inclusion in a weld may be: a Entrapped slag. b Entrapped gas. c Lack of inter-run fusion. d None of the above. 17 Which of the following is a planar imperfection? a Lack of sidewall fusion. b Slag inclusion. c Linear porosity. d Root concavity. 18 For fillet welds it is normal practice in the UK and USA to measure: a Throat thickness. b Leg lengths. c Penetration depths. d Both a and c. 19 In a bend test, when the face of the specimen is in tension and root is in compression, the test is called a a Root bend. b Side bend. c Face bend. d Longitudinal bend. 20 Heavy porosity on the surface of some MMA welds made on a construction site is most likely to be caused by: a Use of the wrong class of electrodes. b Use of excessive current. c Moisture pick-up in the electrode covering. d A bad batch of electrodes. 21 Slag inclusions may be present in: a Manual metal arc welds. b Metal inert gas welds. c Metal active gas welds. d All welds. 22 The main cause of undercut is: a Excessive amps. b Excessive OCV. c Excessive travel speed. d Current too low. 23 Which group of welders is most likely to require continuous monitoring by a welding inspector? a Concrete shuttering welders. b Overland pipeline welders. c Tack welders. d Maintenance welders. 24 Which of the following fillet welds is the strongest assuming they are all made using the same material and welded using the same WPS? a 8mm throat of a mitre fillet. b 7mm leg + 2mm excess weld metal. c Mitre fillet with 10mm leg. d Concave fillet with 11mm leg. 25 A typical included angle for MMA welding a full penetration pipe butt joint is: a 35° b 70° c 90° d Dependent on the pipe diameter. 26 A fillet weld has an actual throat thickness of 8mm and a leg length of 7mm, what is the excess weld metal? a 2.1mm b 1.8mm c 3.1mm d 1.4mm thanks for watching support and subscribe
