T107/Cu107 copper electrode
meets: GB ECu
quite: AWS ECu
Note: Cu107 is based on copper as the core, the coating is a low-hydrogen copper electrode. Good mechanical properties, good corrosion resistance to the atmosphere and seawater, not suitable for welding oxygenated copper and copper. With DC reverse connection, the arc is stable and well formed.
Uses: It is mainly used for welding conductive copper bars, copper heat exchangers, seawater conduits for ships and other copper structural parts. It can also be used for surfacing welding of carbon steel parts corroded by seawater.
