Ultimate-60:

A versatile basic coated electrode designed for joining as well as for repairs which provides ease of operations in all positions with a smooth and stable arc which is easy to strike and restrike, combined with low splatter and with due molten pool. Slag detachabiltiy with little effort. Finely ripped bead with regular profile. Welds of consistent X-ray quality. Weld metal which posseses excellent mechanical properties and displays resistance to cracking caused by heavy stresses and hydrogen. High basicity of slag which helps withstand adverse effect of impurities in base material. Hence its ability to tackle many problems in repair of grey cast iron and to act as buffer layer on hard or work-hardened steel components.

Identification:Name Printed

Applications:Machinery for earth moving and road building. Rotary kiln shells. Blast furnace shells. Structural steel in heavy sections and restrained joints.

Notes on usage:

Ensure that the electrodes are dry. It is a safe practice to redry electrodes for one hour at +300°C and then to keep them in a holding oven maintained at 80°C-100°C,prior to use.
Keep the arc as short as possible and minimise weaving
Clean the weld area of any surface contamination
While preheating may not be required in many cases, it is a good practice to heat the join faces to about 100°C to remove mositure, oil or grease, so as to obtain sound joints.
