Welding: A heat process which fuses three similar metal pieces together utilizing the same type of medium. The two to be joined and a filler to close the joint. Highly suitable for structural stresses (i.e. bridge building, etc.).
Soldering: A heat process which bonds dissimilar metals together using a Lead/Tin alloy. Soldering is not suitable for structural stresses. However, is a strong bond when joining similar metals (i.e. lead used in stained glass windows frames, or copper in roofing systems).
Braising: A heat process which bonds dissimilar metals together using silver/bronze or brass alloys. Suitable for light structural stresses.

Welding and soldering are very similar in principle. Welding is usually for connecting two pieces of, let's say, iron. Think of decorative iron for a door. The welding in this case is a very fine form of connection via high heat and with what's known as a bead. The bead is laid down in a corner, or where the two pieces meet, and the welding torch is applied to the bead in a sweeping motion back and forth. There is an art to welding and you can tell a good job from a bad one by looking at the bead. If there are ripples, uneven bumps and other types of errors, there is a good chance that the welding will not hold properly. If it is smooth and easy to touch (when cooled, of course), that weld was made by an experienced person, probably using a steady hand, welding helmet, gloves and a welding gas tank made specifically for the purpose.
Soldering on the other hand, is a different sort of connection between metals, because there is more to it than just solder and the connection point. Look at an intricate piece of gold jewelry. Look at the joining points. First, the jeweler must rough up the base piece a little bit in the area to be soldered, then clean it extensively. Then, a liquid is put on that will help the solder receive well, meaning it will help the solder to maintain its hold. At this point, a solder is put on. I have used silver solder in strips that I just cut off what I need and then space it along the piece. All the time that I've been doing the above, my soldering iron has been heating up (its a plug-in). I put the tip of the iron on the base piece to heat it and as the solder melts in the joint between, it gets sucked up into the corner on its own. I do not push the solder with the iron in any way. All I do is heat the metal in spots along the piece and the solder naturally does its work. Now, take another look at that piece of jewelry. If the metal is smooth, has no sharp edges or if the prongs are well soldered into the base piece, the jewelry will be quite strong and will last a lifetime. If not, well....

In both cases you join two pieces of metal by adding molten metal between them. In Welding the heat is such that the parts to be joined partially melt as well, forming a very strong bond (they become one piece of metal). In soldering, the parts to be joined do not melt, as the temperature is much lower. The soldering material is a low-melting metal like tin, lead, silver, copper or mostly a mixture of these. The soldering metal creates a bond with the joined parts.

Welding also melts the 2 metals being joined.
Soldering simply melts the solder to join a metal wire to a terminal, for example. Much less heat involved in that.

welding is far stronger than soldering....
soldering is used for light purposes like soldering capacitors,resistors etc onto a circuit board etc etc...you can solder your car,cycle etc...it just wont be strong...
there are different types of welding....but to make the answer simple, the commonly used welding melts the two joining surface and when the molten metal cools down it forms a fixed bond..
also welding is done at a higher temperature

In welding the material is actually melted and fused together. In soldering you are just adding melted lead which basically sticks the material together. With soldering a little heat will break it apart while with a weld you have to grind the material apart.

The difference between welding and soldering is the temperature .
Welding is a much higher temperature than soldering . That is why
oxygen is used with acetylene .

In soldering, metals are joined with the help of a filler metal with a low melting point, < 450°C, and below the melting point of the metals to be joined. Soldering is used for copper and its alloys, zinc, steel and aluminum and its alloys
Braze welding is the process of joining metals whereby the melting temperature of the filler metal is above 450°C but below the melting point of the metals to be joined.

Welding literally melts the iron/steel at the point of contact with high electrial current. Soldering melts an alloy (such as a tin/lead alloy) which 'flows' into accepting metals such as copper when heated (to approx 700ºF +/-) locking both sides together when cooled.

Not exactly. when soldering your putting lead solder in with another metal IE: Copper as in wire from a cord, to bond with another bond-IE: Another cord that's been already leaded for bonding. Then the two are bonded as in gluing.
With welding your actually welding the two metals together, bonding them together.
