4. The carbon steel electrodes of choice generally used in GMAW are?





ANSWER= (B) ER70S-3 and ER70S-6

 

5. Using GMAW and short-circuit transfer mode, the most common shielding gas for carbon steel electrodes are





ANSWER= (C) 75%-Ar and 25% CO2

 

6. In GMAW, the more useful welding transfer technique for joining thin materials in any position is:





ANSWER= (A) Short-arc welding

 

7. The shielding gas, recommended position, and electrode size, when welding aluminum using the spray-arc process at minimum 95A could be:





ANSWER= (C)Argon, flat position, 0.030 in.

 

8. Flux-cored electrode is:





ANSWER= (B) A continuous, GMAW tubular electrode wire specifically designed to weld mild steels using either CO2 gas or Argon-CO2

 

9. What could be the shielding gas flow requirements for small weld pools using short-circuiting and pulsed-spray and globular transfer?





ANSWER= (B) For short-circuiting and pulsed-spray about 10 l/min (0.35 ft³/min) is generally suitable, whereas for globular transfer, around 15 l/min (0.53 ft³/min) is preferred.

 

10. Using GMAW, how argon can be used for welding ferrous materials?





ANSWER= (D) Argon is an inert gas always mixed with other gases such as oxygen, helium, hydrogen, carbon dioxide, and/or nitrogen, for welding ferrous materials.

 

11. Which of the following is not an essential element of an FCAW system?





ANSWER= (D) Wire feeder

 

12. Which of the following is not an essential element of a Flux-cored arc welding system?





ANSWER= (D) Wire feeder.

 

13. When welding aluminum with the GTAW process, what type of welding current is most commonly used?





ANSWER= (A) AC

 

14. The welding processes SAW and ESW are similar in that:





ANSWER= (C)Both use a granular flux, which becomes molten;

 

15.What welding process produces welds in a single pass, with the progression vertically upward along the joint?





ANSWER= (B) ESW
