3.1 Sample Question . 1. In considering the shielding gases argon , helium and carbon dioxide for the Gmaw process , which of the following not true ? a) *They can all produce spray transfer b) *They all produce heave spatter in DC+ c) *All the answer options given d) *They are always suitable for all position welding. 2. Which of the following statements is true ? a) *Ultrasoic testing cannot reveal planar defects perpendicular to the beam direction b) *Magnetic particle testing only works on austentic stainless steel c) *Penetrant testing cannot continually be successfully repeated on the same component d) *Radiography cannot reveal volumetric defects 3. Globular transfer is used in which process ? a) *MMA/SMAW b) *TIG c) *GMAW/MAG d) *SAW 4. According to AWS 2.4 , where does the symbol go for welding on the arrow side ? a) *Above solid line b) *Depends on the joint c) *Always weld where the arrow is pointing d) *Below solid line 5. In MIG/MAG welding what would be affected if the Contact Tip to Workpiece Distance (CTWD) was extended ? a) *Inductance b) *Voltage c) *Amperage d) *Travel speed 6. Overlap at the toe in a fillet weld made by MAG welding , may be caused by : a) *Torch angle being incorrect b) *Using DC +ve polarity c) *Shielding gas flow rate being too low d) *Root gap being too small 7. Which test from below measures the material property knows as ' fracture toughness ' ? a) *Nick break test b) *Fillet weld fracture test c) *Impact test d) *CTOD test 8. According to AWS 2.4 , a weld symbol 'below the references line' refers to : a) *A weld on ' the arrow side ' b) *A weld at ' the root of the joint ' c) *A weld on ' the other side ' d) *None of the answers given - it should be on the dashed line

9. One of the advantages of ultrasonic inspection in relation to radiographic testing is : a) *Access in only required from one side of the component being tested b) *Thin materials can be easily examined c) *The designated work area must be closed off by bariers , therefore safety is increased d) *A permanent image of the defect can be obtained 10. In narrow gap SAW , which of the following is not TRUE ? a) *Is used for thicker plates b) *Operates only with two wires c) *It require special fluxes d) *It used a special welding ahead 11. Which of the following processes is most prone to solidification cracks ? a) *MMA with basic coated electrodes b) *TIG c) *MMA with rutile coated electrodes d) *SAW 12. Clustered porosity found internally in the body of an MMA weld is usually associated with : a) *Damp electrode coating b) *Poor stop start technique c) *The open circuit current being too high d) *Low open circuit voltage 13. Some code require the excess weld metal ( weld cap ) on cross weld joint tensile specimens to be flush , this is because : a) *It is easier to calculate the cross sectional area of the joint when flushed b) *Flushed caps will always break in the weld metal area c) *This is to remove any porosity in the excess weld metal ( weld cap ) d) *Flushed cap have fewer stress raisers and therefore give a more accurate result 14. Which of the following NDE prosesses will BEST detect internal lack of side wall fusion on a MAG (GMAW) weld a) *Radiography b) *Visual c) *Dye penetrant d) *Ultrasonics 15. Due to high heating effect in the electrode when TIG welding (141) with AC it is important that a tungsten electrode used for AC welding is : a) *used straight from the packet without any grinding b) *lightly ground to a slight chamfer (corners only removed) c) *used without grinding and baked at 300'c for an hour before use d) *ground to a fine vertex angle of
