tell me full penetration joint process
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.
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.
Usually it's not considered to be strong enough.
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.
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

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.
Threading joint, weld joint, Flanges joint
A partial penetration joint is a type of weld joint where the weld does not fully penetrate through the thickness of the materials being joined. This results in the weld metal being only partially through the joint rather than completely through. It is often used when full penetration is not required for the application.
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.
TKY weld joints are tubular joints used for welding. They are expressly used for when fabrication of a structure is necessary.
Usually it's not considered to be strong enough.
Socket weld, because it's stronger; butt weld, because it uses less metal. The "best" weld depends on what you're building.
why is it important only to strike the arc in the weld joint
You always weld the side with the preperation first, then if you get incomplete penetration you can grind the back out
