.045

Question 8

14. What are the three things a MIG weld required?

Answer 8

Electricity to produce heat
An electrode to fill the joint
Shielding gas to protect the weld from the air

Question 9

22. What is the most common used welding carbon steel?

Answer 9

ER 70S-6

Question 10

6. In oxygen acetylene cutting, what is the bigger tank?

Answer 10

Oxygen

Question 11

10. What is the last two digits on rod stand for?

Answer 11

It refers to, the flux or shielding on the rod. The higher the number the more shielding, flux, and or metal is deposited. A (XX11) has a lot less coating then a (XX24).

6010,6011,6013,7018, and 7024

Question 15

3. How is the strength of the weld indicated on the rod?

Answer 15

By the first two digits in the rod number

Question 16

12. what is MIG Welding?

Answer 16

MIG welding is most commonly used in fabrication shops where production is high, and the possibility of wind blowing away your gas shielding is unlikely. It is also known as Gas Metal Arc (GMA) or GMAW

Question 17

13. What are three common types of metals which are welded with a MIG welder?

Answer 17

Carbon steel.

• Stainless steel.
• Aluminum, with a special feeder because aluminum wire is very soft.

Question 18

16. What gases are used to welding?

Answer 18

Argon, carbon dioxide, and helium

18. What are the disadvantage of using MIG?

Answer 19

i) Wind is a major factor outdoors
ii) Always need a bottle of gas
iii) It needed to be well maintained
iv) Require clean joint
v) Very annoying to trouble shoot

Question 20

17. What are the advantage of using MIG?

Answer 20

i) Clean with very little smoke
ii) Cheap and fast
iii) Excellent for spot and tack weld
iv) Easy to welds
