Weldex Cutting Rod

Characteristics and applications

  • High arc force for deep penetration and cutting action.

  • Ideal for piercing and cutting all metals by the electric arc process and for removing runners and risers in foundry.

  • The electrodes strikes are easily and achieves clean cuts even on thicker materials.

  • The arc force is excellent and operates at high currents without getting over heated.

Instructions : Set up the work piece so that molten metal can run off easily. It is advisable to execute an up and down sawing movement, pushing the molten metal away with the electrode.

Weldex Electrodes - 7018

IS-EB - 5426 H3JX
AWS : E - 7018

  • An extra low hydrogen, radiographic quality, medium heavy coated, iron powder type electrode that is highly resistant to hydrogen - induced embrittlement.

  • Specially recommended for high strength welds on mild steels, medium carbon and low alloy high strength steels.

  • Deposition efficiency 115%.

  • Used on a variety of steels providing unique hydrogen-free deposits with superior impact resistance at normal and sub-zero temperatures.

  • Recommended applications include critical pressure vessels, high-pressure piping, blast furnace steel work, heavy welded fabrication as replacement for castings, pen-stocks, bridges, atomic reactor shell, overhead cranes, steel gears,loco frames, etc.

Weldex-650

Characteristics and applications

  • A medium coated air-hardening type of electrode for hardfacing on mild steel,carbon and allow steel with hardness of 600 BHN approx.

  • Suitable for machine parts subjected to abrasive wear.

  • For surfacing/rebuilding of crusher hammers, cane cutting knives, conveyor buckets, drilling bits, shears and croppers, oil expellers, mine rails, caterpillar treads,mixer blades, dipper teeth, etc.


Instructions : Keep electrode dry. Use short arc and low welding speed. Employ short stringer beads. A buffer layer of EKNOWELD-7018 on carbon steels and EKNOWELD-18/8/6(S) on stainless steel, is necessary for austenitic managanese steel. Deposit can
only be ground finished. Deposit not more than 2 layers.
