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
First, Butt-weld is short for a butt groove. Welding in a butt-groove starts at the throat of the butt-groove. The first weld point could be a tack-weld: holding the two materials to be welded together. The throat is measured and filler metal and electrode are determined to create the root pass.
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.
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
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.
tell me full penetration joint process
heating then controlled cooling of a weld to reduce stress
Usually it's not considered to be strong enough.
