Question 18

List four advantages of GMAW compared to SMAW.

Answer 18

1. A continuous electrode is used, allowing longer welds without changing electrodes. 2. Faster welding speeds than SMAW. 3. No slag is produced. 4. Finish weld requires less cleaning. 5. Less skill and training are required to weld GMAW than SMAW.

Question 19

List two disadvantages of GMAW compared to SMAW.

Answer 19

1. Equipment cost is higher with GMAW than SMAW. 2. Some welds are harder to reach the gun. 3. Depending on the electrode/wire, GMAW is not as strong as SMAW.

Question 20

When vertical welding, which way should you travel to ensure proper coverage?

Answer 20

Uphill.

Question 21

List five pieces of proper PPE while welding on a job site.

Answer 21

1. Safety glasses 2. Welding gloves 3. Welding helmet 4. Steel toed boots 5. Flame retardant clothing 6. Flash blinders 7. Ear plugs 8. Face shield 9. Hard hat.

Question 22

List three welding positions that were used in our class.

Answer 22

Flat, wall, and overhead.

Question 23

What causes welding voids in SMAW welding?

Answer 23

An arc that is too long causes not enough penetration into the base metal, and breaking of the arc too many times without proper repositioning.
