Description
Copper coated GTAW rod for welding in boiler, pressure vessel, pipeline, and crane construction
as well as in structural steel engineering. Very tough deposit of high crack resistant, nonageing.
Recommended for the temperature range from -30 °C to +500 °C. Good copper bonding
with low total copper content. Very good welding and flow characteristics.
