OVERVIEW

Heavy-Duty Hardfacing with Josef JB620

The Josef JB620 4.00mm Stick Electrode is a premium hardfacing consumable designed to extend the lifespan of industrial equipment subjected to severe abrasion and moderate impact. Engineered by Josef Gas, this electrode is formulated to deposit a wear-resistant overlay on carbon and manganese steels, making it an essential tool for maintenance and repair operations in mining, construction, agriculture, and quarrying industries.

Packaged in a convenient 5 kg tube, the JB620 ensures you have ample material for substantial build-up jobs. The 4.00mm (5/32 inch) diameter allows for higher deposition rates, making it efficient for covering larger surface areas on bucket teeth, crusher jaws, screw conveyors, and bulldozer blades. The electrode produces a weld deposit with a hardness typically in the range of 55-60 HRC, providing a robust shield against grinding wear from earth, sand, and gravel.

Welders will appreciate the smooth running characteristics of the JB620. It offers a stable arc on both AC and DC+ polarity, ensuring consistent bead appearance and penetration. Slag removal is quick and easy, reducing cleanup time between passes. Whether you are reinforcing new parts or restoring worn components to their original dimensions, the Josef JB620 delivers the reliability and performance required for demanding industrial environments.

Key Applications

  • Earth Moving Equipment: Bucket lips, teeth, and sides.
  • Mining & Quarrying: Crusher hammers, mantles, and screens.
  • Agriculture: Plowshares, cultivator sweeps, and augers.
  • General Industry: Conveyor chutes and mixer blades.

FAQ

For a 4.0mm (5/32") hardfacing electrode, a current range of approximately 140 to 190 Amps is typically recommended, depending on the base material thickness and position.

No, the weld deposit is extremely hard (approx. 55-60 HRC) and is generally considered non-machinable. It can only be finished by grinding.

Pre-heating is often recommended, especially when welding on high-carbon steels or thick sections, to prevent cracking in the base metal or the hardfacing layer.

It is generally recommended to apply no more than 2 to 3 layers of hardfacing to avoid cracking and spalling. If more buildup is needed, use a buffer layer electrode first.

The Josef JB620 operates well on both DC+ (Direct Current Electrode Positive) and AC (Alternating Current).

The JB620 is designed for hardfacing, which means applying a hard, wear-resistant surface to metal parts to protect them from abrasion and impact.

Store in a cool, dry place. If the package is opened, it is best to keep them in a rod oven or a sealed container to prevent moisture pickup.
