A consumable electrode is: AN electrode which melts and provides metal to fill the joint
The weld heat affected zone the portion of the base metal adjacent to the weld metal
is: whose properties have been changed due to the heat of
welding
When an arc is formed electricity flows from negative cathode to positive anode
between two electrodes
The magnetic pinch force increases as the square of the current causing smaller and
helps in the process of the smaller droplets to be detached
detaching the molten metal
drops from the electrode tip.
The magnetic force
The electric current for High voltage, low amperage to low voltage, high amperage
welding must be
transformed from
The major advantage of full penetration welds on thick material in one pass
electron beam welding
process is
The progress of welding Vertical up
with Electroslag welding
process is
, is solid state process in which coalescence is produced
Explosion welding through high speed impacting of two or more materials by
controlled detonation
A typical application for joining of rails
thermite welding is
Welding without filler metal autogenous welding
with GTAW process
is referred to as
A typical weld flaw porosity
associated with GTAW
process is
SMAW power sources drooping
typically have a voltampere
curve that is
Once a box of E49XX low 4 hours
hydrogen electrodes has
been opened the electrodes
may remain at ambient
temperature for up to a
maximum of
Shielded Metal ARC establishes an arc between the end of a covered electrode and
Welding (SMAW) process the work piece.
The spray mode of metal high amperage, high voltage and argon-rich shielding gas
transfer is achieved with
digital wire feeders have feedback systems to maintain the preset wire feed
speed
wire designated by CSA Results in weld deposit with a maximum of 8 ml diffusible
standard W48 as an E491T- hydrogen per 100 g of weld metal
9MJ-H8
Self shield flux cored wires better able to tolerate air currents
are
,The AWS classes metal cored solid wires
wire along with
SAW Fluxes that active
significantly influence the
composition of the weld
metal through slag/metal
reactions are called
Resistance welding of Can be done but with greater difficulty due to its low resistivity
aluminum
The plasma arc welding GTAW
process is similar to what
other welding process in
principles of operation
For a flat weld profile and 15 degree travel angle using push technique should be used
good penetration profile
using the MCAW process
What is the effect of tip to decreasing tip to work distance without adjusting any other
work distance (electrical variable will cause a increase in deposition rate
sickout on deposition rate of
submerged are welding
Electrode stick out is From tip of nozzle to end of electrode
measured
Contact tip-to-work is the of the electrode extension and arc length
sum (CTTW)
Increasing electrical sickout decreases voltage, decreases current and increases resistance
Which welding process for Spray transfer
GMAW has large weld pool
and is rather large and
difficult to control out of
position
, Globular transfer
Which welding process for
GMAW has excessive spatter
Which welding process for Short Circuit
GMAW usually has lack of
fusion
what electrodes never go in cellulosic
holding or baking oven
Submerged Arc Welding Requires inter-pass and post weld slag removal
disadvantage

can be done outside
Earth's atmosphere
With tungsten arc, most of electrons
the current across the arc is
carried by
Electrode beam welding has a very narrow weld and heat affected zone

Which welding process is GTAW
non-consumable electrode
process
Which shielding gas does 95% Argon and 5% CO2
GMAW use for spray
transfer
