40 Electrode

Properties

Resistance to Abrasion: Remarkable
Resistance to Impact: Good

Formulation: A high chrome super metal with the addition of rare earth compounds for refinement and the addition of special metals to provide an unprecedented shock absorbing quality. Few other electrodes in existence can provide the outstanding service on crushing equipment.

Weldability

Excellent for both AC and DC. Has a highly efficient arc with no spatter and is slag free. The coating actually goes into the deposit and therefore substantially increases the amount of weld metal deposited. Has extremely high deposition rate.

Economy

40 Crusher Rod is the most economical electrode ever designed for crushers. Most hard surface electrodes give about 18 kg of deposit from 45 kg of electrodes because of stub loss, slag loss, spatter loss and smoking and fuming. Our 40 rod is a most efficient hard surgace electrode. it has no slag loss, no spatter loss and 45 kg of electrodes give nearly 44 kg of deposit. Most operators melt even the stubs into the deposit.

End Uses

While designed for Crushers, our 40 Electrode will give excellent service wherever the job is similarly demanding. Some of the most important uses are:

• Disintegration bars from combination roll crushers
• Scarifier teeth
• Skip hoists
• Power shovel teeth
• Agitator blades in machines
• End bits
• Screens
• Conveyor buckets
• Sheepsfoot tamps
• Impact breaker rotors and bars
• Grader blades

Application Procedure

Can be applied to Carbon or Alloy Steels and Manganese Steel using either AC or DC welding machines (set to reverse polarity). Either a long or short arc may be used.

Apply by making non-connecting deposits over entire area to be coated. Then weld additional passes to fill in between these original deposits. Up to two layers of the electrode may be made.

*Welds cannot be machined or heat treated
