ANSWERS (100% VERIFIED ANSWERS) |ALREADY GRADED A+|
||PROFESSOR VERIFIED|| ||BRANDNEW!!!||
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)
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
The metallurgical changes that occur in the HAZ will be
dependent on the peak - ANSWER-The peak temperature
reached
, 4|Page
Regions that are close to the fusion boundary can experience
temperatures sufficiently high enough that growth of the (Blank)
occurs - ANSWER-Austenitic Grain
one feature of hydrogen cracking is that it only occurs when the
weld and heat affected zone are at high temperatures - ANSWER-
FALSE
Welding over a gap in backing bar of a complete penetration
groove weld may result in a transverse crack in the weld metal -
ANSWER-TRUE
in the heat affected zone of a weld in carbon steel, fast cooling
rates will form a hard - ANSWER-Martensite Structure
Which of the following types of steel is least susceptible to
hydrogen cracking in normal circumstances - ANSWER-Low
strength, low hardness steels
