remain at ambient temperature for up to a maximum of - CORRECT ANSWER✔✔4 hours




Question: Shielded Metal ARC Welding (SMAW) process - CORRECT ANSWER✔✔establishes an
arc between the end of a covered electrode and the work piece.




Question: The spray mode of metal transfer is achieved with - CORRECT ANSWER✔✔high
amperage, high voltage and argon-rich shielding gas

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




Question: SAW Fluxes that significantly influence the composition of the weld metal through
slag/metal reactions are called - CORRECT ANSWER✔✔active




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
