are metals that are not similar, alike and the same
when two metals are being welded together each is taken to the melting point and if there is no bonding between the metals the weld breaks easily. the purpose of welding is to take metal to a melting point and reformulate their bonding at our own requirements so that it makes a good strong joint. if there is no such a joint the purpose of welding becomes unnecessary.so dissimilar metal cannot be welded.
You can't, they are dissimilar metals! Shame as I have been attaching ferrous and non ferrous metals for over 40 years
When two dissimilar metals make electrical contact in the presence of an electrolyte, galvanic corrosion can occur. This phenomenon arises due to the difference in electrochemical potentials between the two metals, leading to the more reactive metal (anode) corroding faster than the less reactive one (cathode). The electrolyte facilitates the flow of ions, exacerbating the corrosion process. To mitigate this, methods such as coatings, sacrificial anodes, or using similar metals can be employed.
No, halogen metals and alkali metals are not the same. They are both groups of elements on the periodic table with distinct chemical properties. Halogen metals are found in Group 17 and are highly reactive nonmetals, while alkali metals are found in Group 1 and are highly reactive metals.
An alloy is a type of metal (specifically, it's a solid solution of dissimilar metals). All alloys are metal, but not all metals are alloys ... pure metals (pure gold or pure copper, for example) are not alloys.
you use a miltimeter and dissimilar metals
Do not have dissimilar metals touching the pipes.

Friction stir is becoming very popular for this
It doesn't. But it can act as the electrolyte if you stick two dissimilar metals into one.
Placing two dissimilar metals in a fruit creates a chemical reaction that generates a flow of electrons, resulting in an electric current. This process is known as a fruit battery, where the acidity of the fruit acts as an electrolyte to facilitate electron transfer between the metals.
When two dissimilar metals are placed in a fruit, a chemical reaction occurs between the metal and the acids in the fruit. This creates a potential difference between the two metals, leading to the flow of electrons and the generation of an electric current. This phenomenon is known as a fruit battery.
Dissimilar metals, output is in millivolts.
When 'dissimilar' metals touch, they can create one of the prerequisites for galvanic corrosion.

Welding should only be done between similar metals. Installing welded flanges to connect two dissimilar metals would be the preferred method of connection.
