Welding is done at a high electric current to melt and meld steel together. Soldering is a process that requires an electric soldering gun that melts a steel wire to "stick" the wire to the adherent surfaces. Soldering is done at low temperatures, usually below 450 C. Its used mainly on small circuit boards, were welding may be used on a vast array of steel projects, to connect any thickness of steel.

In laymans terms, welding is the process of heating the edges of two pieces of the same metal and basically melting them together. Soldering is the process of creating a bond between two surfaces using a metal that melts at a lower point than the two metals being connected.

The basics of welding is generally joining two similar metal by molten similar metal between them at very high temp which is higher to its melting point. On the other side soldering done by the alloy metal whose melting temp is relatively much lower and it helps to joins metal to metal relatively less tightly.
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld puddle) that cools to become a strong joint, but sometimes pressure is used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces.
Soldering is a method of joining metal parts using an alloy of low melting point (solder) below 450 °C (800 °F). Heat is applied to the metal parts, and the alloy metal is pressed against the joint, melts, and is drawn into the joint by capillary action and around the materials to be joined by 'wetting action'. After the metal cools, the resulting joints are not as strong as the base metal, but have adequate strength, electrical conductivity, and water-tightness for many uses

I think in welding the main metal melts and makes an alloy with the welding metal that fills the gap. In soldering just the soldering metal melts and fills the gap.

Don't know a lot about it but welding is usually joining pieces of metal with a arc welder and soldering uses a soldering iron and is usually for electric components. Don't know if that is much help.

Welding needs high temperature and metal to be joined is melted at its melting point. However in soldering you need not have to melt the metals to be joined rather you have to melt an another metal of low melting point and the use it as joining material (like paste).

Solder looks more like silver. A weld will look like rolled steel

Welding is joining parts for structural stability soldering is joining them for conductivity

Soldering is for electrical joints and made of Lead and tin.
Welding is for joining metals.
