Restraint is usually higher in - ANSWER-Groove welds than in
fillet welds
The G-BOP test is suitable to study crack susceptibility relating
to - ANSWER-Hydrogen -cracking in the heat affected zone
What is the heat input efficiency of the SMAW process -
ANSWER-50 - 85
In some steels a very slow cooling rate may procedure a -
ANSWER-soft, coarse grain structure with low toughness
Sometimes an unwanted microstructure can be refined and
altered by reheating - ANSWER-Into normalizing range, where it
will re-crystalize and transform back into small austenite grains
Hydrogen entrapped in the solidified weld metal - ANSWER-Can
not escape into the atmosphere before it causes cracking
,2|Page
According to CSA W59, the SAW process can be used without
preheat if adequate energy input is ensured. This is applicable
when making - ANSWER-Fillet welds in one pass
When welding alloyed structural steels the risk of cracking
depends mainly on - ANSWER-chromium and nickel content
When weldling structural steels the main reason for preheating
is - ANSWER-to allow hydrogen to escape
Crack can form in the parent material beneath the weld. This
form of cracking is called - ANSWER-Lamellar tearing
Good fracture toughness normally requires - ANSWER-A fine
grain structure
The solidification structure that results from a slow welding
speed can be described as - ANSWER-A short weld pool with
solidifying crystals growing from the back of the pool
Beyond a certain thickness the cooling rate is independent of
thickness. At about what thickness does this occur in carbon
manganese steels - ANSWER-38mm (1-1/2")

Steels can be grouped into three zones based on their carbon
content and carbon equivalent. The HAZ hardness of which
group of steels can be controlled by cooling rate - ANSWER-
Zone 2
In general, the higher the heat input - ANSWER-The slower the
weld cooling rate
Steels can be grouped into three zones based on their carbon
content and carbon equivalent. Steels in which Zone are not
prone to hydrogen cracking - ANSWER-Zone 1
Heat input from welding - ANSWER-determines the amount of
component distortion during phase transformations
Hydrogen cracking in carbon manganese steels - ANSWER-Can
occur in many areas of the welds
An Arc of 300 amps and 30 volts will produce - ANSWER-9000
joules per second (300 x 30)
, 4|Page
The peak temperature within the heat affected zone changes
with distance from the fusion line. What peak temperature is
exceeded in partially transformed region - ANSWER-723
According to CSA W59, a damaged container of low alloy SMAW
electrodes must be - ANSWER-re-baked at temperatures
between 230 C and 260 C
During arc welding there is a zone adjacent to the weld metal
that reaches high temperatures but does not melt. What is the
name of this region - ANSWER-Heat affected zone
Not all the heat energy produced during welding will enter the
plate as heat energy. What is this phenomenon known as -
ANSWER-the efficiency
With Manual welding the technique will influence the energy
input. Which technique involves higher energy input - ANSWER-
Weaving techniques
Considering that increasing the heat input will reduce the
cooling rate, is the following statement true or false: - ANSWER-
For thick plates, cooling rate is inversely proportional to the
heat input
