Important Notes
- 1. Strictly follow the requirements of the oxy-acetylene flame or plasma spray welding process.
- 2. When using small and medium-sized spray welding guns, it is appropriate to choose a powder of 150 purpose, and when using large spray welding guns, choose a powder of 150/+320 purpose.
- 3. If the alloy powder has moisture absorption phenomenon, or the storage period is more than 3 months, it should be dry (120℃, 22 hours) before use.
Frequently Asked Questions
Q:
What are the primary applications for DG.Ni60A alloy powder?
It is suitable for oxy-acetylene flame or plasma spray welding processes, and is commonly used for wear and corrosion resistance. It is ideal for the preventive protection and repair of sliding wear parts, such as wire drawing drums, CAMs, plungers, and rolling machine conveyor rolls.
Q:
What is the melting temperature and hardness of the spray welding layer?
The powder melting temperature ranges from 960℃ to 1040℃, and the resulting spray welding layer achieves a hardness of HRC58-62.
Q:
How should the alloy powder be pre-treated if it absorbs moisture or is stored for a long time?
If the alloy powder experiences moisture absorption, or if the storage period exceeds 3 months, it must be dried at 120℃ for 22 hours prior to application.
Q:
Which powder mesh size should be selected based on the spray welding gun size?
For small and medium-sized spray welding guns, it is recommended to choose 150 mesh powder. For large spray welding guns, a powder size of 150/+320 mesh is appropriate.
