An E71T-1 electrode designation is working for which welding process?
Flux core arc welding
Why is rate of change of flux linking primary and secondary coils the same?
The 'rate of change' applies to the flux itself, and has nothing to do with it linking the primary and secondary windings. There is only one flux, so of course the rate of change is 'the same'.
Why is flux required for soldering?
flux acts as a wetting agent in the soldering process, reducing the surface tension of the molten solder and causing it to better wet out the parts to be joined.
What type of flux is used for welding copper?
The primary purpose of flux is "to clean". It mixes with the elements in the molten puddle and removes impurities. As it cools it floats to the surface and creates the slag which prevents Oxygen from attacking the Iron.
How do you improve the flux linkage between the primary and secondary windings in a transformer?
by using an iron core
An E71T-1 electrode designation is working for which welding process?
Flux core arc welding
What is the main difference between FCAW and GMAW?
GMAW (solid wire) vs. FCAW (flux-cored wire). The Most important difference between FCAW and GMAW is welding wire,
What is the rock Pyroxenite used for?
The primary use of pyroxenite is as a flux in the steel production process.
Why is the purpose of using core in transformer?
To maximise the magnetic linkage and flux density between the primary and secondary windings.
In transformer core flux depends on voltage whereas leakage flux depends on current?
In a Transformer, Core flux is the difference of primary flux and Secondary flux which are opposite to each other in direction. There difference is equal to the no load flux at all loads. So, some of primary flux passes through the core and remaining becomes leakage flux (Because Secondary flux forces it to get out of the core). Same is the case with Secondary flux. Now, flux is directly proportional to Voltage and Current. When Current increases due to increased load (and voltage remains same): Then both primary and secondary flux increase. Because both of them increase, so there difference remains same. And all remaining flux is forced out. Hence leakage flux increases with current, but Core flux remains constant. When Primary Voltage is increased: Then only primary flux increases. So difference of this new increased primary flux and previous same secondary flux increases. Hence Core flux increases with voltage, But leakage flux does not. That's how In transformer core flux depends on voltage whereas leakage flux depends on current.
What is the purpose of a flux?
The purpose of flux is to clean oxides from metal surfaces to ensure a clean bond in soldering or brassing them together. without a proper flux soldered and brazed joint integrity is unreliable.
What are the two american welding society abbreviations for the arc welding processes that melt a tubular electrode with alloys deoxidizers and slag formers in their cores?
One would be FCAW. Flux Cored Arc Welding.

Why is a flux needed for brazing?
You must use flux while brazing because the flux prevents oxides from forming while the metal is heated. The flux also serves the purpose of cleaning any contamination left on the brazing surfaces.
