Gouging Nozzle ｜ Precise Control of Molten Metal Flow for Gouging Operations

• The Gouging Nozzle is specifically designed for gouging applications (metal removal / grooving)

• Precisely controls groove width and depth, reducing unnecessary metal removal

• Compatible with both Acetylene and LPG, depending on the model

• Available in models compatible with Gouging Torch Z and A-Type Cutting Torch Z

In repair work, removal of existing weld beads, and surface preparation before subsequent processes, using a torch alone is not sufficient. The Gouging Nozzle is a critical component that defines the direction of oxygen injection and the flow behavior of molten metal. It enables controlled metal removal, minimizes impact on the base material, and improves precision in industrial applications.

When removing weld beads or correcting defects, selecting an unsuitable nozzle can result in grooves that are too wide or uneven in depth, leading to additional surface finishing work. Choosing the right Gouging Nozzle allows operators to “remove only what is necessary,” reducing time and improving overall efficiency.

The Gouging Nozzle is designed to inject cutting oxygen in a concentrated, well-directed stream, enabling precise control of molten metal flow while maintaining flame stability during gouging. Groove width and depth can be adjusted according to nozzle size, making it ideal for repair work, weld correction, and surface preparation prior to production processes.

Gouging Nozzles are widely used for removing existing weld beads, correcting casting or welding defects, surface preparation before machining or welding, as well as repair work in steel structures and heavy industries. Selecting a Gouging Nozzle that matches the torch type, fuel gas, and required groove dimensions enables precise control of the gouging process, reduces excessive material removal, minimizes rework, and improves overall repair efficiency.

The Gouging Nozzle is a key component that enables precise and safe metal removal and surface conditioning. Choosing the appropriate model for the application helps reduce working time, lower hidden costs, and enhance long-term repair quality.

Q: How does a Gouging Nozzle differ from a Cutting Nozzle?

A: A Gouging Nozzle is designed for removing and grooving metal, rather than fully cutting through material like a Cutting Nozzle.

Q: How should a Gouging Nozzle be selected?

A: Selection should be based on the torch type, fuel gas, and the required groove width and depth.

Gouging Nozzle: A nozzle that controls oxygen injection and molten metal flow in gouging operations

Gouging: A process of removing or grooving metal using flame and oxygen

Width / Depth: The width and depth of the groove produced during gouging
