SOC Welding Flashcards
- How opened do you want the oxygen tank to be?
All the way to back seat
- What is Welding position?
1G = FLAT 2G = HORIZONTAL 3G = VERTICAL 4G = OVER HEAD
- What types of electricity operate on welding rod?
A/C and D/C
- What are the three component of Arc Welding machine?
Ground clamp, Electrode Clamp, and Welding Rods (Electrodes)
- What are the four types of Welding?
SMAW/ shielded metal arc welding (stick welding)
MIG / Metal inert gas welding
FCAW / Flux core arc welding
TIG / Tungsten arc wedling
- What is MIG Electrode types?
It is manufactures standard code to identify types of electrode
ER- An electrode or filler rod that is used in either a wire feed or TIG welding.
70- A minimum of 70,000 pounds of tensile strength per square inch of weld.
S -Solid wire.
6- The amount of deoxidizing agent and cleansing agent on the electrode.
- What is MIG welding wire range?
.023
.030
.035
.045
- What are the three things a MIG weld required?
Electricity to produce heat
An electrode to fill the joint
Shielding gas to protect the weld from the air
- What is the most common used welding carbon steel?
ER 70S-6
- In oxygen acetylene cutting, what is the bigger tank?
Oxygen
- What is the last two digits on rod stand for?
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).
- What types of voltage and polarity type used in MIG?
D/C electrode positive
- What color is the acetylene pipe and oxygen pipe?
Acetylene pipe = Red
Oxygen pipe = Green
- what is the most common welding rods?
6010,6011,6013,7018, and 7024
- How is the strength of the weld indicated on the rod?
By the first two digits in the rod number
- what is MIG Welding?
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
- What are three common types of metals which are welded with a MIG welder?
Carbon steel.
- Stainless steel.
- Aluminum, with a special feeder because aluminum wire is very soft.
- What gases are used to welding?
Argon, carbon dioxide, and helium
- What are the disadvantage of using MIG?
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
- What are the advantage of using MIG?
i) Clean with very little smoke
ii) Cheap and fast
iii) Excellent for spot and tack weld
iv) Easy to welds
- What is the name of the tool used to light the torch?
Torch striker
- what is the first two digits on rod stand for?
Tensile strength per square inch of weld. (ex 60XX stand for a minimum of 60,000 pounds tensile strength PSI)
- What are the three welding techniques?
Whipping, Circle, and Weaving
