|
|
| |
| Preformed Tungsten Carbides for High Pressure
Abrasion |
| Cobalarc 4 is the ultimate in welding technology. |
| |
| It has autogenous fume shielding over preformed
carbides in a tubular form, which gives the user genuine
low heat input and infinite shelf life by dint of its nonhygroscopic
coating. |
| |
| The electrode deposits fine tungsten carbide embedded
in a hard and tough martensitic-austenitic matrix, which
is suitable for extreme abrasion with low to moderate
impact. It resists all forms of abrasion and wear.
Deposition efficiency is very high when compared with
coated electrode. |

| ALLOY BASE |
| Fe, W, C, Co |
| |
| SPECIAL FEATURES |
- Exceptional resistance to severe abrasion and
moderate to heavy impact at low to medium
temperatures
- Low spatter level
- Unmatched deposition rates - high integrity
deposits.
- Compared to solid cored electrodes, the current
requirement is low so the dilution by parent metal is
contained to a minimum
- Non-hygroscopic coating needs no storage
precaution – infinite shelf life
|
| APPLICATIONS |
| Rock drill bits, oil well drills, churn drills, sand gravel
chutes, coal cutter bits and picks, bulldozer end plates,
grader end bits, feed screens, scraper for sand and
refractory materials, fan and pump impellers, pug mill
augers and knives, choppers, post hole auger teeth,
feed screws, mixer blades / paddles etc. |
