WELDFAST LH 18 - (NACE) Characteristics

A basic coated extra-low hydrogen all position welding electrode with deposition efficiency of approx. 110%. The weld metal has excellent toughness even at -50°C and satisfies X-ray, ultrasonic and radiographic requirements. Electrode gives smooth and stable arc, with easy slag removal even from first pass in a vee groove. The weld metal which contain about 1.2% Mn, is extremely resistant to cold and hot cracking and tri-axial stressing.

Re-drying temperature is 300°C for 1 hr
