The flux is there to remove any oxidation from the surfaces of the metals to be welded.

What is the difference betweenTig wire stick welder?
a stick welder needs to replace his electrode regularly and the flux coating is on the outside while a tig machine constantly feeds the wire and the flux is produced by a filler gas
Why electrodes are coated?
it insulates the electrode preventing formation of the arc except at the tipsit melts and acts as a protective flux over the joint, preventing oxidation
Difference between leakage flux and mutual flux?
when a current flow through the coil then flux produced around the coil . if the flux linked same produced coil only then the flux is said to be leakage flux. flux produced by one coil ,but linked with another coil then the flu is said to be mutual flux.
What is the meaning of ER70S-6 of welding electrodes?
E, eletric welding. R, rod or filler. 70, tensile strength. S, solid wire. 6, chemical composition.
What are the differences between the natures of dc flux and ac flux?
dc flux is caused by dc current (flux and current are proportional), it is a constant value. Put an inductor (or transformer winding) across a battery and you will get dc flux. ac flux is caused by ac current (flux and current are proportional), it is a moving value, the flux moves with the current, typically cyclical but the waveform is arbitrary as long as we're moving.
What two methods are used when adding flux to the brazing rod?
one of the method is manually dipping the filler rod in a canister of loose flux as the weld proceeds
How is the cast iron welding rod made?
Cast iron welding rod is designed for the SMAW process which is built by flux and a filler metal that suits the base metal's chemical & mechanical properties.
What is the outer coating on a welding rod?
The flux is the outer coating on a welding rod. The flux is a very important part of the welding rod.
Can weld without flux is possible?
You can arc weld & then the flux will be in the rod.
What is welder slag?
Welder slag is a byproduct resulting from the welding process, often forming a layer on top of the welded joint. It consists of the residue from the flux used in the welding rod or wire, which helps protect the weld pool from impurities and contaminants while it cools. Slag is typically removed after welding to inspect the quality of the weld and ensure proper fusion.
How do you welding?
in order to make a weld you need a welder The above post is a little simplistic but you basically weld using gas or electricity to melt the base metal allowing you to add metal via a flux coated or bare rod. If using gas to melt you would use a bare rod to add - if using electricity to melt you would add a bare rod (with a covering gas) or flux coated rod (which forms its own gas). There are so many welding processes that techniques and equipment vary widely.
What does weld rod mean?
They are mild and low alloy metals . the rods are iron coated for a better distribution of the flux metal. They are normally used for general fabrication, heavy sheet metal work and shelving.
Can filler rod type 308L be used for pipe 304?
YES
Shielded metal arc welding is sometimes called welding?
It is sometimes called "stick welding", because of the filler metal. The filler metal is in the form of heavy wire coated with flux.
What are F No. in Gtaw filler metals QW-404?
There are 5 variables for PQR which reflect the filler metal: QW-404.5 - F-No. All solid and and flux cored wire are assigned to F-No. 6. QW-404.6 - A -No. For the same base metal the common used wire (solid or flux cored) have the same A-No.
What is the difference betweenTig wire stick welder?
a stick welder needs to replace his electrode regularly and the flux coating is on the outside while a tig machine constantly feeds the wire and the flux is produced by a filler gas
What is welding?
When you heat a piece of metal so that part of it melts, that melted part can stick to another piece of metal and when it cools and hardens, the two pieces of metal will be connected by a very solid bond, effectively making them a single piece. That is welding.
