LoTherme-690

AWS: SFA

EN ISO CODE:

LoTherme-690 is a hard surfacing electrode, operates well in all positions. The deposited weld metal has exceptional abrasion wear resistance in combination with resistance to impact & mild corrosion. Evenly rippled, deposits permit heavy build-up without danger of cracking. In most cases, it can be used direct on the job without the necessity of depositing buffer layers.

Applications:
Typical applications include surfacing Sugar Mill cane cutting knives, shredder & fibrizer hammers, anvil, chipper knives, conveyor bucket lips, shear blades, shovels dredger and elevator bucket lips rock crushers, rock drills, tractor grousers and paddlers, Impellers, Spindles, Crane Hooks, Crane Shoes, Mill Hammers, TRPF Roller (Toothed Roller Pressure Feeder), Muller Tyres, Clinker Mill, In crushing applications etc.

Approvals

Weld Metal Hardness:

55-62 RC

Welding Techniques:

Ensure that the electrodes are perfectly dry before use. In case of moisture pick- up, re-dry the electrodes at 200°C for 01 hour before use. Clean the weld area free from any surface contamination. Hold a short arc length and weld it with stringer beads.

Electrical Characteristics: DC (±)/AC
