The answer is entirely dependent on the material/s you are welding. Consult ASME for your specific application.
It is the only type of weld you can make to seal this type of joint. There are flange ends that can be welded onto pipe with a butt weld, but sockets and slip-ons must be fillet welded.
To be fully welded out plus a fillet of @ 6mm to reduce the stress concentration factor at the bottom toe.
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 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.
One would weld a flange tight by firstly establishing which type of joint they were welding. One of the most common is welding a neck flange. For this you would need to ensure that both pieces of material to be welded are melted on the first bead of the weld. You would continue around the pipe until you reach the beginning. Once back at the start you need to ensure that the final bead is higher than the joint being welded. The weld should be approximately 1/16th of and in to 1/8th of and inch from the pipe to the flange.

A weldolet is a fitting you weld on a (run) pipe, and then butt weld a branch pipe to it. A tredolet is a fitting you weld on a (run) pipe, and then screw a threaded branch pipe to it. Some people call this a threadolet A sockolet is a fitting you weld on a (run) pipe, and then socket weld a branch pipe to it. A nipolet is the same as a weldolet or thredolet but has an elongated branch connection. You have to specify if it's a welded or threaded nipolet.
Furnace butt welded pipe refers to the manner in which a pipe is to be welded. The skelp itself is heated to a specific temperature in a furnace. You would then weld the longitudinal seam forge. This is a method that works on fence posts or pipes required for low pressure services.
The meaning of dia inch is the number of weld joints multiplied by the dia of a given pipe size, since the weld joints is on the 6" pipe, the calculations should be 1 weld x 6" = 6 dia inch.
A GI pipe is welded to a GI pipe by using solder and flux. The pipe is heated up, flux applied, and then solder allowed to flow into the joints to create a secure bond.
Weldolet has a Bevelled end to butt weld the pipe whereas in sockolet the pipe/tube goes inside it and there it is fillet welded.
To be fully welded out plus a fillet of @ 6mm to reduce the stress concentration factor at the bottom toe.
The past tense of weld is welded.
there are 3 types of welded joint 1-butt weld butt weld is the type which need usually 4 mm clearance between the 2 edge of pipe or plate you want to weld it. 2-socket weld 3-seal weld

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