Butt weld is a type of joint for welding.At this type,the connection area is put in front of each other.Another method of connection is "Socket weld"in which two parts are male and female,one goes into the other then welding operation is done.

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.
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.

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.

Socket weld, because it's stronger; butt weld, because it uses less metal. The "best" weld depends on what you're building.
Butt weld and groove weld are two common types of weld joints used in welding processes. A butt weld is a type of weld where two pieces of metal are joined together along their edges in a single plane, creating a smooth, flush surface. On the other hand, a groove weld is a type of weld where a groove or channel is created in one or both of the pieces being joined, and the filler material is deposited into the groove to create the weld. Both types of weld joints are used in various applications depending on the specific requirements of the project.
A fillet weld in any single continuous weldmay underrun the nominal fillet weld size specified by2 mm [1/16 in] without correction, provided that theundersize portion of the weld does not exceed 10% of thelength of the weld. On the web-to-flange welds on girders,underrun shall be prohibited at the ends for a lengthequal to twice the width of the flange.
