Welding rods.
Welding of compacted surfaces of parts of energy, oil and other fittings, operating at a temperature of up to 600 °C and a specific pressure of up to 800 kgf/cm 2 . These can be valves and seats of internal combustion engines, knives of guide screws, worm presses. Also welding saw teeth to wood or other cutting tools.
Another application of rods is welding of the sliding supports of the trunnions of the chisel legs. Strengthening and restoration of parts operating under conditions of abrasive wear with moderate impacts at temperatures up to 500 °C.
Field of application:
- parts of centrifugal pumps;
- shut-off fittings;
- oil and gas pipelines;
- backfill devices of blast furnaces;
- agricultural machinery.
