It is the heat affected zone. It differs in every weld. but a good rule of thumb is .25" on either side of the weld
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.
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.
To unite by a butt weld.
two to three mm
no some of the heat is radiated away in forms of light and heat waves
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.
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
tell me full penetration joint process
Usually it's not considered to be strong enough.
27.5 degrees
heating then controlled cooling of a weld to reduce stress
