0153348001 - ESAB SAW Flux Delivery Nozzle for A2/A6 Systems

Precision Flux Delivery for Submerged Arc Systems

The ESAB 0153348001 Flux Nozzle is an engineered component designed to facilitate the precise deposition of granular flux in Submerged Arc Welding (SAW) applications. In the SAW process, the integrity of the weld bead is entirely dependent on the consistent coverage of the arc by a layer of flux. This nozzle acts as the final interface between the flux delivery system—typically a gravity-fed hopper or a pressurized recovery unit—and the weld joint. By channeling the flux directly around the electrode wire, it ensures that the arc remains fully submerged, thereby preventing atmospheric contamination and stabilizing the electrical characteristics of the weld.

Manufactured to ESAB's exacting standards, this nozzle is specifically compatible with the A2 and A6 series of automatic welding heads and tractors. These systems are workhorses in heavy fabrication, shipbuilding, and pipe mills, where downtime must be minimized. The nozzle is constructed from materials selected for their resistance to the abrasive nature of welding fluxes, which often contain hard minerals like silica, manganese oxide, and calcium fluoride. Over time, the constant friction of flowing granules can wear down inferior nozzles, leading to erratic flow patterns or blockages. The ESAB 0153348001 maintains its internal geometry to ensure a smooth, laminar flow of flux, which is critical for high-speed automated welding.

Proper maintenance of the flux delivery system is often overlooked but is vital for quality assurance. A damaged or clogged nozzle can lead to "flash-through," where the arc becomes visible, or insufficient slag coverage, resulting in porosity and poor bead aesthetics. This OEM replacement part restores the original functionality of the welding head, ensuring that the flux burden is sufficient to support the molten pool and shape the bead correctly. It is an essential spare part for maintenance teams managing ESAB SAW equipment fleets.

Integration is seamless, designed to fit standard ESAB mounting points on the flux hopper outlet or the torch assembly. Whether utilized in single-wire, twin-wire, or tandem SAW configurations, this nozzle plays a pivotal role in the material handling aspect of the process. By directing the flux exactly where it is needed, it also helps in minimizing flux waste and improving the efficiency of vacuum recovery systems.
