flows from negative cathode to positive anode
The magnetic pinch force helps in the process of the detaching the molten
metal drops from the electrode tip. The magnetic force - correct answers

electrodes may remain at ambient temperature for up to a maximum of -
correct answers 4 hours
Shielded Metal ARC Welding (SMAW) process - correct answers establishes
an arc between the end of a covered electrode and the work piece.
The spray mode of metal transfer is achieved with - correct answers high
amperage, high voltage and argon-rich shielding gas
digital wire feeders - correct answers have feedback systems to maintain the
preset wire feed speed
wire designated by CSA standard W48 as an E491T-9MJ-H8 - correct
answers Results in weld deposit with a maximum of 8 ml diffusible hydrogen
per 100 g of weld metal
,Self shield flux cored wires are - correct answers better able to tolerate air
currents
The AWS classes metal cored wire along with - correct answers solid wires
SAW Fluxes that significantly influence the composition of the weld metal
through slag/metal reactions are called - correct answers active
Resistance welding of aluminum - correct answers Can be done but with
greater difficulty due to its low resistivity
The plasma arc welding process is similar to what other welding process in
principles of operation - correct answers GTAW
For a flat weld profile and good penetration profile using the MCAW process -
correct answers 15 degree travel angle using push technique should be used
What is the effect of tip to work distance (electrical sickout on deposition rate
of submerged are welding - correct answers decreasing tip to work distance
without adjusting any other variable will cause a increase in deposition rate
Electrode stick out is measured - correct answers From tip of nozzle to end of
electrode
Contact tip-to-work is the sum (CTTW) - correct answers of the electrode
extension and arc length
Increasing electrical sickout - correct answers decreases voltage, decreases
current and increases resistance
