It isn't.

It's called soldering when you join two pieces of metals together using a 3rd metal with a very low melting point. Welding, then both the "parent" metals and the added metals are melted. Usually at a lot higher temperature.

What alloy would you use to join metal parts explain?

There are several different alloys used for this purpose, depending on the requirements:solder, used in a process called soldering where low temperatures are required to avoid damage and the alloy does not need to provide strength to the joint (solder is traditionally an alloy of tin & lead but many modern solders have been reformulated to replace the lead with nontoxic metals)brass, used in a process called brazing where it is undesirable to melt the parts being joined but the alloy must provide strength to the joint (brass is an alloy of copper and zinc)alloys similar to that used in the parts themselves, used in a process called welding where both the alloy and the parts are melted and commingled to provide a joint as strong as the original metal parts themselves

What alloy is used in railwaytrack?

No Alloy is used. Mild Steel is the most common metal used for railway tracks due to its' relatively low cost and compatibility for generqal welding, workability and strength, compared to all other metals.
