Objective:

The goal of this effort was to quantify the reported productivity and mechanical property improvements from the use of TipMate™ Nozzles for shipyard applications. The Nozzle is a ceramic electrode extension that will enable higher deposition rates and reduced distortion without the loss of electrode support and arc stability typically experienced when an extended electrode is used in submerged arc welding (SAW). The simple addition of this low-cost (<$100) component added to an existing SAW head can easily provide a 25-40% increase in productivity. The productivity benefits are often equivalent to those seen with more elaborate tandem arc, AC square wave or twin-arc systems, but at a fraction of the cost and without the need for procedure re-qualification under many codes.
