Mac Trode E6502
AWS E8015-B6
Descriptions & Applications:
An E502-15 low hydrogen manual metal arc electrode using a silicon free, low nitrogen C Mn core wire with a moisture resistant, chemically basic flux with a controlled iron powder addition. All positional electrode with good slag control. Easy to strike electrode which produces porosity free weld deposits. Exhibits good crack resistance and excellent resistance to oxidisation at temperatures up to 650°C. For assembly welding of creep resistant steels with 5% Cr, 0.5% Mo and closely related grades. Used for pipe welds in the petrochemical industry.
