ANSWERS (100% VERIFIED ANSWERS) |ALREADY GRADED A+|
||PROFESSOR VERIFIED|| ||BRANDNEW!!!||
Welding codes normally require a waiting period between welding
and inspection because - ANSWER-hydrogen induced cracks
(HICC) may occur several hours after the weld has solidified
What is the main reason for pre-heating - ANSWER-to reduce the
hydrogen content of the weld by diffusion
The tekkan test is suitable to study crack susceptibility in a -
ANSWER-Groove weld
Lamellar tearing is most likely to occur in which of the following -
ANSWER-thick T-groove welds
During welding, the proportion of heat energy that enters the plate
is referred to as its efficiency. What is the efficiency dependent on
- ANSWER-The welding process
,2|Page
When the alloy content of a structural steel us sufficiently high
that HAZ hardness cannot be controlled - ANSWER-The only
remaining factor which can be controlled is hydrogen content
In arc welding, the area of the base metal adjacent to the fusion
line which is not melted is called - ANSWER-The Heat Affected
Zone
Process that are not hydrogen controlled may require - ANSWER-
Higher preheat temperatures for thicker plates
What joints provide the most dilution - ANSWER-The square
groove weld with zero root opening
what electrode type is often required if stress relieving operation
are planned on the fabricated structure to maintain the same yield
strength and tensile strength - ANSWER-Molybdenum-bearing
electrodes
,3|Page
The type of microstructure and susceptibility to cracking of a heat
affected zone depends on - ANSWER-Hardenability of the steel
and the weld cooling rate
The level of preheat required is typically derived from the -
ANSWER-plate thickness and the carbon content of the steel
Submerged arc welding has a process efficiency of - ANSWER-
90% to 99%
Covered electrodes that use basic coatings - ANSWER-Reduce
electrodes that use basic coatings
The extent to which grain growth in HAZ occurs depends on -
ANSWER-The energy input
For given set of welding parameters, an increase in travel speed
will - ANSWER-Decrease the heat input
, 4|Page
Why is it possible for some multipass welds to have higher
toughness than a single pass weld - ANSWER-The passes in the
multipass weld refine the underlying grain structure
The amount of dilution of weld metal by the parent metal -
ANSWER-is mostly dependent on the joint design and welding
process
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
