AMT 116 WELDING

Question 1

is the electrode that actively participates in the electrochemical cell’s chemical reaction; whereas the inert electrode is the electrode that does not actively participate in the electrochemical cell’s chemical reaction.

Answer 1

Active Electrode

Question 2

Types of Electrodes

Answer 2

Active Electrodes, Inert Electrodes

Question 3

Primarily used in large volume production work

Answer 3

GMAW

Question 4

also called a welding electrode, is a tool used to join metals together. It creates the heat needed to melt and fuse metals during welding. There are different kinds of electrodes, depending on the materials and the job you’re doing.

Answer 4

Electric rod

Question 5

Types of Rods

Answer 5

Alternating Current (AC) Arc Welding Electrodes, Light Coated Electrodes, Bare Electrodes, Pure Tungsten Electrodes, Flux-Cored Electrodes, Low-Hydrogen Welding Electrodes, SMAW Welding Electrode, Bronze/Alloy Brazing Rods, Carbon Electrodes, Consumable Electrodes, Copper Electrodes

Question 6

It melts both electrode or filler wire and the work metal

Answer 6

GMAW

Question 7

Uses inert gas( such as argon and helium) enveloping the electrode and filler rod to protect it from oxidation

Answer 7

GTAW

Question 8

Types of Electric Arc Weld

Answer 8

SMAW, GMAW, GTAW

Question 9

These have a special coating that helps protect the weld and make the welding process smoother. They’re used with an AC power source.

Answer 9

Alternating Current (AC) Arc Welding Electrodes:

Question 10

Formerly called as Metal Inert Gas (MIG) welding

Answer 10

GMAW

Question 11

is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld. It’s one of the most widely used welding methods due to its versatility and simplicity.

Answer 11

Shielded Metal Arc Welding (SMAW)

Question 12

also known as TIG welding, is a type of electric arc welding that uses a non consumable tungsten as an electrode. Filler rod is needed manually (almost in the same manner as the oxyacetylene torch) .

Answer 12

Gas Tungsten Arc Welding

Question 13

Also known as Stick Welding

Answer 13

SMAW

Question 14

It gives us a high quality welds with good appearance and there are no slags

Answer 14

GMAW

Question 15

Simplest form of welding

Answer 15

SMAW

Question 16

best suitable in aircraft maintenance and repair

Answer 16

GTAW

Question 17

These rods are designed to reduce the amount of hydrogen in the weld, which helps prevent cracking. They are commonly used for stronger metals.

Answer 17

Low-Hydrogen Welding Electrodes

Question 18

These rods are made of carbon and are used in welding where strong, non-reactive bonds are needed.

Answer 18

Carbon Electrodes

Question 19

Also known as Stick welding electrodes, these are popular in arc welding. They have a coating that burns off during welding to protect the weld from air.

Answer 19

SMAW Welding Electrode

Question 20

helps keep the metal in contact with the welding rod, preventing sparks from flying and therefore helping to ensure a smooth, consistent weld.

Answer 20

Flux

Question 21

These are used for brazing, a process similar to welding but done at lower temperatures. They’re great for joining different types of metals.

Answer 21

Bronze/Alloy Brazing Rods

Question 22

These have no coating at all. They’re mostly used for welding non-critical metals where extra protection isn’t needed.

Answer 22

Bare Electrode

Question 23

These rods have a hollow core filled with flux. The flux helps protect the weld from contamination, making it easier to weld outdoors or in dirty environments.

Answer 23

Flux-Cored Electrode

Question 24

These have a thin coating that helps control the weld’s quality and stability but doesn’t provide as much protection as other electrodes.

Answer 24

Light Coated Electrode

Question 25

These are often used in TIG (Tungsten Inert Gas) welding. They have high heat resistance and are great for precise work.

Answer 25

Pure tungsten Electrode

Question 28

These are electrodes that melt and become part of the weld. Most welding rods fall under this category.

Answer 28

Consumable Electrodes

Question 30

Copper rods are used for welding electrical components since copper is a good conductor of electricity and heat.

Answer 30

Copper Electrodes
