FusoFlex

Ultimate-16Ni:

Ease of operation in all positions except vertical top to bottom.Slag detachability with ease.Finely ripped beads with regular profile. Presence of 0.50-1.0% nickel to enhance impact property at temperatures down to minus 50 degrees. Radiorgraphic soundness of a high order.

Identification:Name Printed

Application:Designed with particular attention to welding of fine-grained steels having tensile strength 500-600Mpa combined with high degree of notch toughness at subzero temperatures down to minus 50 degrees. Suitable for welding aluminium - killed steels for low temperature used in LPG tankers,storage tanks and offshore constructions.

Notes on usage:

Ensure that electrodes are dry. It is a safe practice to redry electrodes for one hour at 300°C & then to keep them in a holding oven maintained at 80°C-100°C, prior to use.
Use short arc & minimise weaving to the extent possible to obtain sound welds with high toughness.
Control heat input with appropriate currents & interpass temperature.
Clean the weld area of any surface contamination.
