LOW HEAT INPUT WELDING ALLOYS
RASI WE -25

A SPECIAL ELECTRODE PRODUCING OUTSTANDING QUALITY WELDS ON CAST IRON. DEPOSITS ARE FULLY MACHINABLE.

CHARACTERISTICS
RASI WE 25 contains specially formulated flux coating that enables the electrode to produce very smooth arc, at very low temperature which is essential for cast iron welding to avoid dilution with the base metal and minimise the heat input. The electrode produces crack free machinable weld deposits on all weldable cast iron.

APPLICATIONS
RASI WE 25 is specially reommended for sound and crack free weld deposits on gray cast iron, spheriodal iron, malleable cast iron to themselves or to each other or to steel. this electrode can effectively be used in joining the above castings to monel or copper alloys. Repair welding of valve bodies, engine blocks, sprockets, gears, pump casings and filling the cavities of new defective castings are some of the many other similar applications.
