The procedure of surfacing the sealing surface of ZFVALVES seat is as follows:            

1. The wire number is Stellite 6.            

2. Welding wire shall be filament (diameter 3.2 mm or 4.0 mm)            

3. Argon Arc Welding (TIG)            

4. Surfacing thickness not less than 4.5 mm            

5. Preheating temperature 150-200 degrees Celsius            

6. The interlayer temperature is about 500 degrees Celsius, the number of surfacing layers is 2, the post-weld heat treatment temperature is 700 degrees Celsius, and the heat preservation time is 3 hours.            

7. Surfacing width according to design drawings            

8. No porous impurities or cracks are allowed in the surfacing layer.           

9. Hardness of weld layer HRC38-42            

*Attention: Surface roughness of valve seat before surfacing is above Ra12.5 micron. Surface contamination such as rust, grease and water should be strictly cleared. No cracks, spalling and other defects should be allowed.
