0818971880 - ESAB A6S Submerged Arc Tandem Welding Head 156:1 Ratio

High-Performance Automation for Heavy Industry

The ESAB A6S 156:1 SAW Tandem Head is a cornerstone component for high-productivity automated welding systems. Designed as part of the renowned A6 modular system, this head assembly is engineered to meet the rigorous demands of heavy fabrication, shipbuilding, and pressure vessel manufacturing. The "Tandem" designation indicates its capability to support multi-wire welding processes, a technique essential for achieving high deposition rates and optimizing travel speeds in thick-plate applications. By utilizing multiple wires in the same weld pool, the A6S Tandem Head significantly reduces production time while maintaining superior weld quality.

At the core of this unit is the 156:1 gear ratio. This specific gearing is meticulously calculated to provide the ideal balance between wire feed speed and torque, ensuring consistent feeding for standard submerged arc wire diameters. In automated welding, the stability of the wire feed is critical; even minor fluctuations can lead to arc instability or defects. The A6S drive mechanism minimizes these risks, delivering a smooth and continuous feed that results in uniform bead profiles and deep penetration. The robust gearbox is sealed and lubricated for long service life, reducing maintenance intervals and downtime in 24/7 production environments.

Integration is seamless with the A6S system. Whether mounted on a traveling tractor, a beam carriage, or a stationary column and boom, this head adapts to various configurations. Its modular nature allows for easy customization and parts interchangeability, simplifying inventory management for large facilities. The head works in perfect synchronization with ESAB's advanced process controllers, such as the PEK, allowing operators to fine-tune parameters like voltage, current, and travel speed with precision. For industrial operations seeking to maximize throughput without compromising on mechanical properties, the ESAB A6S Tandem Head represents a strategic investment in efficiency and quality.
