Questions And Answers Practice Questions with
Solutions Newest 2026-2027 | Already Graded A+
SAW Fluxes that significantly influence the composition of the
weld metal through slag/metal reactions are called - ANSWER-
are classified in conjunction with welding wire forming a flux
designation
A welding arc consists of a - ANSWER-high current and low
voltage
The heat of the welding arc is used to - ANSWER-locally melt
the base material and filler material to create fusion upon
solidification
Welding using GTAW process with current set to DCEN -
ANSWER-30% arc heat at the electrode and 70% arc heat at the
work
,2|Page
The function of the ingredients in the electrode coating of
SMAW electrodes is to - ANSWER-provide a gas shield, slag
covering, scavengers, arc stabilization and additional alloying
elements
The temperature for holding low hydrogen electrodes -
ANSWER-120 C
The GMAW process uses (Blank) to shield the molten weld
from the atmosphere - ANSWER-external shielding gas
The flux cored arc welding is an arc welding process usually in
the semi-automatic mode, consisting of: - ANSWER-A constant
current power supply, a continuous speed wire feeder, a welding
gun, and a continuous filler metal electrode with a hallow core
containing flux and other ingredients
Welding is process a joining process that by definition requires
application of - ANSWER-Either heat or pressure
Name the two main methods of arc shielding - ANSWER-flux
shielding and gas shielding
,3|Page
Which direction do the electrons flow in an electrical are -
ANSWER-Cathode to anode
In are welding, the electric are is intensely hot with temperature
exceeding - ANSWER-30,000 C
How does the arc voltage and arc stiffness change when the arc
length is increased - ANSWER-Arc voltage increases and arc
stiffness decreases
What type of penetration and weld width can be expected when
using DC positive (GTAW) - ANSWER-Shallow penetration
and a wide weld
Which polarity is chosen most often for direct current GTAW
welding of steels and why - ANSWER-Direct current electrode
negative. More heat is produced at the work piece leading to
deeper weld penetration
Why must shielding gas for GTAW be completely inert -
ANSWER-Presence of active gases like oxygen and carbon
dioxide the tungsten electrode and the limit its life.
, 4|Page
Two advantages of GTAW process - ANSWER-It gives high
quality deposits, and the process can be used to weld virtually all
metals and alloys
Why is SMAW a very commonly used welding process -
ANSWER-It provides great flexibility in terms of the broad
range of materials and their thicknesses that can be joined in all
welding positions
SMAW uses constant current or constant voltage - ANSWER-
constant current
Why is care necessary in the proper storage and handling of
electrodes for welding steels - ANSWER-Improperly stored
electrodes can pick up moisture leading to increased weld metal
hydrogen content and therefore increased risk of cold cracking
in the weld zone
GMAW uses Constant Voltage or Constant Current - ANSWER-
Constant Voltage
Which metal transfer would be applied to Cast Iron - ANSWER-
GMAW: Short Circuiting
