ELECTRODES FOR TIN-BRONZES AND SURFACING.
Gemet 702 DC, ECuSn-C
AWS SFA 5.6: E Cu Sn C
A special basic coated electrode for welding and surfacing of copper, brass and bronze. Deposited weld metal is free from porosity. The weld bead is smooth uniform and slag is easy to remove. Weld metal has higher hardness and higher tensile strength & yield strength compared to ECuSnA electrodes.
