1. faying surface: the mating surface of a member that is in contact with or in close
proximity to another member to which it is to be joined.
2. joint: the junction of the workpieces that are to be joined
3. supplementary welding symbols: are used to provide complemen-
tary information to the basic elements of a basic welding symbol
4. weld symbol: a symbol that designates each type of weld, it is drawn in contact
with the reference line and graphically represents the the type of weld to be made
5. left side: the vertical line of a weld symbol must always be on the in
the weld symbol
6. arrow side: a weld symbol placed below the reference line of a welding symbol
is the be made on the
7. plate to be bevelled: for bevel and groove welds, if an arrow has a break then
the arrow is pointing toward the
8. closest: in a welding symbol with multiple reference line the sequence of opera-
tions start with the line to the the arrow
9. to be removed: if an R printed in the rectangle of a backing bar designation for
a welding symbol, the backing bar is after welding
10. consumable insert: a is a piece of filler metal placed at the root of
a weld that is completely fused into the root of the joint
11. square: the symbol for a consumable insert in a welding symbol is a placed
on the opposite side of the reference line from the weld
12. Gouge to sound metal: GTSM in the tail of awelding symbol means
13. dotted lines: the designation of joint to be prepared after assembly of two
members is showed using to draw the weld symbol
14. seal weld: welds intended to provide a water tight seal are have printed
in the tail of the welding symbol
15. right: a fillet welds length is shown to the of the weld symbol
16. left: the size of a fillet weld is shown to the of the weld symbol
17. pitch: is the space between sections of weld on centers of an intermittent
weld
18. Staggered Intermittent Weld: offset weld symbols on both sides of the refer-
ence line designates a
19. 1.5 to 6.0 mm: CSA and AWS standards allow GTAW filler metals in what
diameters?
20. : Electrode packaging must have what information
21. GTAW: porosity, electrode contamination, solidification cracks down the center-
line of the weld bead (especially in craters) and tungsten includes are common
discontinuities of what welding process
22. Manual metal arc welding: MMAW stands for

, cwb welding inspector Questions And Answers
23. constant current: what kind of power source has a drooping volt-ampere curve
24. AC SMAW: benifits of using are :
-arc blow is rarely a problem
-suitable for welding thick sections with large diameter electrodes
25. risk of electrocution, limited choice of electrodes: the cons of us AC SMAW
are
26. 120: low hydrogen rods should be stored in ovens at degrees celcius
27. once: low hydrogen electrodes can only be rebaked how many times?
28. 230-260 2 hours: low hydrogen electrodes exposed to ambient temperatures
and humidity should be rebaked at degrees Celsius for _
29. calcium carbonate: is an important ingredient in low hydrogen flux
because it produces a fast freezing slag
30. largest: when welding with SMAW the practicable electrode should be
selected
31. repair: SMAW is typically used for and maintence, among other things
32. constant voltage: GMAW uses what kind of power source
33. DCEP: GMAW almost exclusively uses the polarity
34. v shaped: When welding with solid steel or stainless steel wires in GMAW you
should use drive rolls
35. knurled: When welding with metal cored or flux cored wires in GMAW you
should use drive rolls
36. u shaped: When welding with aluminum wires in GMAW you should use
drive rolls
37. Ionization potential: the amount of voltage required to produce a plasma col-
umn in a gas is called the
38. more voltage: gases with a higher ionization potential require to initiate
an arc
39. 0.6 to 1.6mm: GMAW electrodes are usually in diameter
40. incomplete fusion, undercut, porosity: common discontinuities for GMAW are
41. GMAW: higher duty cycle, higher depostion rate, no slag or flux and less need
for stop and starts is an advantage of what process
42. -40: shielding gases generally have a dew point of degrees celsius
43. FCAW: porosity, worm tracks, lack of fusion/penetration and hydrogen induced
cracking are common discontinuities of what process
44. CSA W48: what canadian standard gives the requirements for FCAW electrodes
45. DCEP: most applications of singe wire SAW use what polarity
46. reduced penetration, risk of incomplete fusion: DCEN can be used in single
wire SAW to achieve higher deposition rate but results in :
