Question: A consumable electrode is: - CORRECT ANSWER✔✔AN electrode which melts and
provides metal to fill the joint




Question: The weld heat affected zone is: - CORRECT ANSWER✔✔the portion of the base metal
adjacent to the weld metal whose properties have been changed due to the heat of welding




Question: When an arc is formed between two electrodes - CORRECT ANSWER✔✔electricity
flows from negative cathode to positive anode




Question: The magnetic pinch force helps in the process of the detaching the molten metal
drops from the electrode tip. The magnetic force - CORRECT ANSWER✔✔increases as the
square of the current causing smaller and smaller droplets to be detached




Question: The electric current for welding must be transformed from - CORRECT
ANSWER✔✔High voltage, low amperage to low voltage, high amperage

preset wire feed speed




Question: wire designated by CSA standard W48 as an E491T-9MJ-H8 - CORRECT
ANSWER✔✔Results in weld deposit with a maximum of 8 ml diffusible hydrogen per 100 g of
weld metal




Question: Self shield flux cored wires are - CORRECT ANSWER✔✔better able to tolerate air
currents




Question: The AWS classes metal cored wire along with - CORRECT ANSWER✔✔solid wires

Question: Resistance welding of aluminum - CORRECT ANSWER✔✔Can be done but with
greater difficulty due to its low resistivity




Question: The plasma arc welding process is similar to what other welding process in principles
of operation - CORRECT ANSWER✔✔GTAW




Question: For a flat weld profile and good penetration profile using the MCAW process -
CORRECT ANSWER✔✔15 degree travel angle using push technique should be used




Question: What is the effect of tip to work distance (electrical sickout on deposition rate of
submerged are welding - CORRECT ANSWER✔✔decreasing tip to work distance without
adjusting any other variable will cause a increase in deposition rate




Question: Electrode stick out is measured - CORRECT ANSWER✔✔From tip of nozzle to end of
electrode




Question: Contact tip-to-work is the sum (CTTW) - CORRECT ANSWER✔✔of the electrode
extension and arc length




Question: Increasing electrical sickout - CORRECT ANSWER✔✔decreases voltage, decreases
current and increases resistance
