A butt weld is where the diameter of the pipes welded together are the same, a socket weld is where a larger diameter pipe is fitted into a smaller one. In making a butt weld, the pipes (or pipe and fitting) usually have an angle machined or ground into the outside corner, so when they are placed together face-face, there is a circumferential V shaped gap serving as the weld prep. In a socket weld, the pipe is inserted into the socket, backed off slightly to make a gap between the end of the pipe and the bottom of the socket, and the weld is made around the outside diameter of the socket to the outside diameter of the pipe. The gap at the bottom of the pipe prevents thermal expansion from stressing the joint during or after welding.
A butt weld is a weld made between two straight cut profiles , a socket , or plug weld is made between a surface and a hole.
A socket weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a valve or fitting, and then fillet welded between its outside diameter and the fitting end. Generally used for piping whose nominal diameter is 2 inches (50 mm) or smaller.

Socket weld, because it's stronger; butt weld, because it uses less metal. The "best" weld depends on what you're building.

Socket weld joints are an easy and fast method of weld joints. Socket welding is preferred mainly on low pressure joints and small bore joints.
two to three mm
I would say how ever much gap you have from the face of the flange, to the end of the pipe inside the flange. Put a tape measure in it. It should be like 1/4 inch.

No. Additionally, welded socket joints do not receive internal purging with an inert gas (i.e. argon).
