Notes: 1. The electrode shall be baked at 200 ° C for 1 hour before welding.

2. The oxide on the surface of the workpiece must be brushed clean before welding, after 500-600 ° C preheating and then surfacing welding.

3. After welding, the workpiece should be tempered at 600-700 ° C for 1 hour before slow-cooling, or the workpiece immediately into the dry and hot sand box or ash in slow-cooling.

4.The surfacing layer shall be roughed first. If defects are found, the surfacing layer shall be welded and cooled slowly according to the above steps.

 

Description: D667 is low hydrogen sodium type coating, casting solmayite alloy welding core surfacing electrode. Using DC reverse connection, electrode positive electrode. The surfacing layer under 500 ° C has good wear resistance, corrosion resistance and cavitation resistance. Above this temperature, the hardness of surfacing layer drops sharply.

Usage: used for surfacing welding occasions which require strong wear resistance, corrosion resistance or cavitation resistance. For example, the oil industry in the centrifugal cracking pump bushings, ore crusher parts and diesel engine valve cover.
