The first weld made when joining two pipes with beveled edges is called the "root pass." This initial weld establishes a foundational joint at the root of the bevel, ensuring proper penetration and alignment of the joint before subsequent layers or passes are added. It is crucial for the strength and integrity of the overall weld.

What is the first weld called when welding pipes with beveled edges?

The first weld made when welding pipes with beveled edges is called the "root pass." This initial weld is crucial as it establishes the foundation for the joint, ensuring proper penetration and fusion between the two pipe edges. The root pass is typically performed with a smaller electrode and lower heat settings to control the weld pool and prevent burn-through. Subsequent passes, known as fill and cap passes, are added to complete the joint.

When would you use a butt weld?

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.
