This process, called the butt-weld process is the basis for our current pipe-making procedures. In his method, thin sheets of iron were heated and drawn through a cone-shaped opening. As the metal went through the opening, its edges curled up and created a pipe shape. The two ends were welded together to finish the pipe. The first manufacturing plant to use this process in the United States was opened in 1832 in Philadelphia. So the method is the two sides are welded as they butt together without overlapping. The same method is used to weld two pipes together as they are butted together and welded around the seams.
According to most codes and standards there are two basic weld joint configurations the fillet joint (laps and tees) and butt joints ( square and bevel grooves). A butt joint is where the edges of the material come into contact on a lateral line versus a fillet joint which makes contact on a perpendicular or transverse line (imagine a capitol "T or Y" for Fillet and a "__ __" for Butt. Typical butt joints have a square, single piece beveled, or both pieces beveled. The terms used are "Square Butt" (two square pieces), "Single Bevel Groove" (one piece beveled), "Double Bevel Groove" (one piece beveled on both sides, "Single Vee Groove" (both pieces beveled forming a V) and "Double Bevel Groove" ( both pieces beveled to form a V on both sides or top and bottom). Depending on the welding process, material type and thickness, groove welds generally produce better joint penetration and post weld stress reduction.

When your britches are always falling ----- You have way too much spare time. If you can't supply a knowledgeable answer DON"T. Some individuals rely on this forum to get answers they can't get anywhere else.
It's where you lay two pieces of metal flat on the bench, shove 'em together and weld the seam between them.
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 support the molten metal while it is cooling
To unite by a butt weld.
Whenever 2 pcs. of metal come together at an angle to each other. Butt welds are 2 pcs of metal that meet edge to edge.
two to three mm
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 heat affected zone. It differs in every weld. but a good rule of thumb is .25" on either side of the weld
tell me full penetration joint process
Usually it's not considered to be strong enough.
