AMT 116 WELDING Flashcards
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.
Active Electrode
Types of Electrodes
Active Electrodes, Inert Electrodes
Primarily used in large volume production work
GMAW
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.
Electric rod
Types of Rods
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
It melts both electrode or filler wire and the work metal
GMAW
Uses inert gas( such as argon and helium) enveloping the electrode and filler rod to protect it from oxidation
GTAW
Types of Electric Arc Weld
SMAW, GMAW, GTAW
These have a special coating that helps protect the weld and make the welding process smoother. They’re used with an AC power source.
Alternating Current (AC) Arc Welding Electrodes:
Formerly called as Metal Inert Gas (MIG) welding
GMAW
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.
Shielded Metal Arc Welding (SMAW)
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) .
Gas Tungsten Arc Welding
Also known as Stick Welding
SMAW
It gives us a high quality welds with good appearance and there are no slags
GMAW
Simplest form of welding
SMAW
best suitable in aircraft maintenance and repair
GTAW
These rods are designed to reduce the amount of hydrogen in the weld, which helps prevent cracking. They are commonly used for stronger metals.
Low-Hydrogen Welding Electrodes
These rods are made of carbon and are used in welding where strong, non-reactive bonds are needed.
Carbon Electrodes
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.
SMAW Welding Electrode
helps keep the metal in contact with the welding rod, preventing sparks from flying and therefore helping to ensure a smooth, consistent weld.
Flux
These are used for brazing, a process similar to welding but done at lower temperatures. They’re great for joining different types of metals.
Bronze/Alloy Brazing Rods
These have no coating at all. They’re mostly used for welding non-critical metals where extra protection isn’t needed.
Bare Electrode
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.
Flux-Cored Electrode
These have a thin coating that helps control the weld’s quality and stability but doesn’t provide as much protection as other electrodes.
Light Coated Electrode
These are often used in TIG (Tungsten Inert Gas) welding. They have high heat resistance and are great for precise work.
Pure tungsten Electrode
These are electrodes that melt and become part of the weld. Most welding rods fall under this category.
Consumable Electrodes
Copper rods are used for welding electrical components since copper is a good conductor of electricity and heat.
