What rod do you use for hardfacing?
We recommend the best welding rod D938 for hardfacing
D938 is a graphite coated high carbon and high chromium cast iron hard facing electrode.
Welding rod coating has excellent performance, good conductivity, and stable arc without splashing.
There is very little mineral slag forming agent in the coating, and during the welding process .
There is no need for slag cleaning, and the efficiency of deposited metal is as high as 85%.
The deposited metal has high hardness and excellent wear resistance, gas corrosion resistance.
What are hardfacing electrodes used for ?
Used for surfacing wear-resistant surfaces that withstands certain impact loads and requires high resistance to abrasive wear, such as
wear resistant plate and wear resistant ring (commonly known as eye plate) for concrete delivery pump S pipe valve, hammer head of hammer type coal mill .Overlay welding of material trays, sintering crusher toothed rollers, etc.
Why people like to choose the welding rods for hardfacing?
1. Strong wear resistance: Hardfacing welding rods can provide high hardness, so they can be used in environments with severe wear and avoid damage to machinery and equipment;
2. Good corrosion resistance: Hardfacing welding rods can reduce the damage of machinery and equipment in corrosive environments and extend the service life of the equipment;
3. Strong anti twisting ability: The deposited metal of the hardness overlay welding rod can withstand high stress, reducing the twisting deformation of the equipment in high stress environments;
4. Good hot working: the hardfacing electrode can be further processed under the heating state, and can also be processed after welding to improve the controllability of the equipment manufacturing process;
5. Easy to process: The hardness overlay welding rod can be processed and plastic deformed using ordinary processing tools, making it convenient for processing and manufacturing;
6. Stable production process: The production process of hardness surfacing welding rods is highly automated, with stable production efficiency and product quality.
