Understanding Welded Joints: What Are They Called?

Explaining Welded Joints and Their Terminology

Welded joints are essential components in various industries, allowing for the creation of strong and durable connections between metal pieces. These joints can be classified into different types, each serving a specific purpose based on the design and application requirements.

Butt welds are a commonly used type of welded joint where two pieces of metal are joined along a single plane by welding their ends or edges. This type of weld is favored in piping systems, structural connections, and other applications where a seamless joint is required.

Socket welds involve inserting one piece of pipe into a recess on another piece and then welding around the top. These welds are typically used for smaller pipe diameters and provide a strong connection for various applications.

Flange welds are used to attach flanges to pipes, valves, or other equipment, allowing for easy assembly and disassembly when maintenance or repairs are needed. This type of welded joint enables a secure connection between components.

Threaded welds is not a standard term in welding practices, as threads are usually not welded due to the risk of damaging the threads during the welding process. Instead, threaded connections are typically achieved through other means, such as threading or mechanical fastening.

In conclusion, welded joints can also be commonly referred to as butt welds when describing the type of joint created by welding two flat surfaces together edge-to-edge. Understanding the terminology and characteristics of different welded joints is crucial for ensuring the integrity and strength of metal structures in various applications.
