OK Tubrod 15.13

The following items have been added to your list


A multi-purpose, all-positional wire for use with Ar/CO2 gas or CO2 producing spatter-free welds with a self-releasing slag over a wide application base, but it is ideally suited for shipbuilding thanks to its ease of use and excellent feedability. Vertical-up welds, with or without the use of a backing material for root runs, are the hallmark of this wire, where deposition rates of 4-5 kg/h can be achieved.
