Mastering Orbital Welding: A Complete Guide

Introduction to Orbital Welding

Definition and Overview

Orbital welding systems utilize advanced welding equipment and tools to achieve high quality and precise welds in various applications. Orbital welding is an advanced automatic welding process where the welding arc is mechanically rotated 360 degrees around a stationary workpiece, such as a pipe or tube, with consistent current and shielding gas flow. This approach enables the production of consistently high-quality welds with minimal human intervention, offering a high level of precision in the welding process. The required precision is enhanced by controlling the welding power supply and electrode use. Orbital welding equipment includes orbital welders and specialized machines designed specifically for tube and pipe orbital welding applications, often referred to as orbital tube welding.
