Produces uniform welds with low porosity and high repeatability.
Gravity welding, also known as gravity-assisted welding or gravity-driven welding, is a welding technique that utilizes the force of gravity to help join two metal pieces together. This method is often used for welding pipes, tubes, and other cylindrical components. gravity welding
In a shipyard, you have miles of horizontal T-joints (stiffeners welded to plates). Gravity welding rigs are light, cheap, and require no electricity beyond the welding machine itself. A single welder can monitor two or three gravity rigs simultaneously, tripling their output. For repair work in remote locations—a pipeline in a trench or a bridge girder—a gravity clamp is a robust, low-tech solution that a robot cannot match.

At its core, gravity welding is a variation of manual metal arc (MMA) or shielded metal arc welding (SMAW). But instead of the welder manually pushing the electrode downward as it melts, a simple pivoting device holds the electrode. In a shipyard, you have miles of horizontal
The result is a process that requires virtually no operator skill once the rig is set up. You simply start the arc and let physics take over.
