OVERCORD

APPLICATIONS/ PROPERTIES:

Rutile- cellulosic type electrode for the welding of

a large variety of components. It is particularly

suitable for the welding of root runs in pipe, for

tight joint preparations and for the welding of

storage vessels and oil tanks. Overcord has

excellent all- position weldability including verticalup

and down and is ideal for fillet welding in the

vertical- down position It has a deposition

efficiency of 60% .
