A welding boss is a pipe fitting used to provide a reinforced branch connection on a run pipe, typically for the installation of instruments, gauges, or small-diameter outlets. It is made by forging high-quality metal—usually carbon steel, stainless steel, or alloy steel—under high pressure, resulting in a dense and durable structure capable of withstanding high pressure and temperature conditions. The welding boss is designed to be welded directly onto the pipe surface, providing a strong, leak-proof, and permanent connection. It features a beveled end for easy welding and is often used in industries such as oil and gas, petrochemical, power generation, and process piping where reliable connections for instrumentation or vent/drain lines are required.
